Program Basics7 Q
Are conventional and conforming the same thing in Martin County?
Close cousins. 'Conventional' means not government-insured. 'Conforming' means the loan also fits Fannie Mae/Freddie Mac rules and stays under the county loan limit — $832,750 for one unit in Martin County for 2026. Every conforming loan is conventional; a conventional loan above the limit is a jumbo.
Fannie Mae vs Freddie Mac — does it matter to me in Martin County on a conventional construction loan?
Rarely in a way you'd feel. Both purchase conventional loans under similar guidelines, and both support single-close construction financing. Where their rules differ at the margins — income treatment, certain property types — we simply route your Martin County file to whichever set fits your situation. That routing is our job, not your worry.
What is the conforming loan limit in Martin County on a conventional construction loan?
For 2026, the one-unit conforming limit in Martin County is $832,750, with higher limits for 2–4 unit properties. That's the ceiling for a standard conventional loan — including a construction-to-permanent loan — before jumbo pricing applies. It resets each year, so the number moves.
Can first-time buyers use a conventional construction loan in Martin County?
Absolutely — and there's a bonus: the 97% LTV option (just 3% down) on a fixed-rate loan requires at least one borrower to be a first-time buyer. Pair that with gifted funds or family land and a first home can be a brand-new build near Palm City or Port Salerno. First-time doesn't mean existing-home-only in Martin County.
Should I choose a fixed rate or an ARM for my build in Martin County on a conventional construction loan?
Fixed-rate loans keep the payment identical for the full term — maximum certainty, and required for the 97% LTV option. ARMs start with a fixed period (5, 7, or 10 years) then adjust with the market. On construction loans, fixed is the Martin County default because you're already managing build-phase variables; but the right answer depends on how long you'll keep the home. We model both.
What loan terms are available on conventional loans in Martin County?
Fixed-rate terms of 10, 15, 20, and 30 years, plus 5-, 7-, and 10-year ARMs. The 30-year fixed is the most common on Martin County construction-to-permanent loans, but a 15- or 20-year term saves substantial interest for buyers with room in the budget. We show the amortization side by side and let you pick.
Who is a Conventional loan the strongest fit for in Martin County?
Buyers with a 680+ score and roughly 10% or more to put down — especially anyone building a second home, wanting removable mortgage insurance, or sitting above USDA income limits. If that sounds like you, Conventional deserves a first look. In Martin County — including around Hobe Sound and Indiantown — the same guideline applies.
Eligibility & Credit8 Q
Can self-employed borrowers get conventional construction loans in Martin County?
Yes — self-employment is a documentation path, not a penalty. Generally two years of business history (sometimes one, with the right profile), tax returns, and stable or rising income. Depreciation and other paper write-offs often get added back, so qualifying income can exceed what your bottom line suggests. Martin County contractors and business owners build with conventional loans routinely.
What credit score do I need for a conventional loan in Martin County?
The published floor for manual underwriting is 620, and automated underwriting evaluates the full file rather than a single cutoff. Higher scores improve mortgage-insurance and pricing tiers, so there's a real payoff to each band you climb. If you're close but not there, we'll map the fastest score-building path before your Martin County build, not after.
Can rental or ADU income help me qualify in Martin County on a conventional construction loan?
Yes — on a 2–4 unit build, projected rent from the other units counts as qualifying income per the appraiser's rent schedule. Accessory dwelling unit rent can be considered too under the right program. Build a duplex near Palm City, and the tenant's rent is helping you qualify before a single brick is laid in Martin County.
Is manual underwriting available on the construction program in Martin County on a conventional construction loan?
No — the file must have an automated approval through Fannie Mae's Desktop Underwriter. That makes the pre-qualification run we do upfront genuinely meaningful: the same engine that decides is the one we test. In Martin County — including around Hobe Sound and Indiantown — the same guideline applies.
Does the conventional loan use my middle credit score in Martin County?
The representative score drives the decision — and it matters twice on construction: 680 gets you approved, 700 or higher waives requalification at completion. If you're sitting at 690, a few months of targeted credit work before closing can simplify your entire build. In Martin County — including around Palm City and Port Salerno — the same guideline applies.
Can a co-signer who won't live in the home help me qualify in Martin County on a conventional construction loan?
Yes — conventional loans allow non-occupant co-borrowers, with the loan capped at 95% LTV on automated approvals when their income is used. A parent's income helping a child build in Martin County is the classic setup. The co-borrower shares full legal responsibility, so it's a family decision worth making with clear eyes.
Are there income limits on conventional loans in Martin County?
Standard conventional loans have no income limits at all — earn whatever you earn. Only the affordable programs (HomeReady/Home Possible) cap income, at 80% of area median, in exchange for their perks. So high earners aren't excluded and moderate earners get a discount lane. Martin County buyers fit somewhere on that spectrum, and we place you deliberately.
I own several properties already — can I still build conventionally in Martin County on a conventional construction loan?
Yes — conventional financing allows up to ten financed properties for investors, with reserve requirements that step up as the portfolio grows. Second-home and investment construction both work. This is where conventional runs laps around government programs, which are owner-occupied-only. Martin County portfolio builders live in conventional territory.
Property, Land & Site6 Q
Can I include an ADU or in-law suite in my conventional build in Martin County?
Yes — an accessory dwelling unit can be part of the plans on a one-unit build, and its rental income may even be considered in qualifying under the right program. Multigenerational living and rental offset are both strong Martin County plays. Zoning is the gatekeeper, so we confirm the parcel allows it before plans are drawn.
Is there an acreage limit for conventional loans in Martin County?
No fixed cap — conventional guidelines care about the property being residential in character, not a working farm, with value supported by comparable sales. Large Martin County parcels finance regularly; the appraiser just needs similar acreage sales to lean on. We assess the comp landscape before you contract on big land.
Can I use construction-to-permanent financing for a condo in Martin County on a conventional construction loan?
No — attached condo units and co-ops are specifically excluded from construction-to-permanent financing under Fannie Mae guidelines. Detached homes, townhome-style attached units in PUDs, and 1–4 unit properties are the lane. If your Martin County plans involve a condo project, different financing structures apply and we'll walk you through them.
Can I build a second home with a conventional construction loan in Martin County?
Yes — second-home construction is fully supported, with as little as 10% down. This is territory government programs can't enter: FHA, VA, and USDA are owner-occupied-primary only. A vacation build near the water in Martin County runs on conventional financing, full stop.
Can I build anywhere in Martin County with a conventional loan?
Yes — conventional financing has no geographic eligibility maps. City lot in Stuart, suburban parcel near Palm City, or acreage past Port Salerno — all fair game, provided zoning allows residential use and the appraiser can find comparable sales. That freedom is a core conventional advantage over USDA's rural-only rules.
Can I finance a tiny home in Martin County on a conventional construction loan?
Tiny homes are treated as manufactured housing and must have at least 600 square feet of living area — which rules out most true tiny builds. If your plan clears 600 square feet on a permanent foundation, let's look at it. In Martin County — including around Hobe Sound and Indiantown — the same guideline applies.
Construction & Builders20 Q
Can I do some of the work myself to save money in Martin County on a conventional construction loan?
Limited sweat equity is sometimes possible — think landscaping or painting after key inspections — but structural, electrical, plumbing, and anything requiring a licensed trade must go through your general contractor. Draw funds only release for verified professional work. Talk to us about which Martin County line items can realistically be owner-performed before you count the savings.
What standards must the finished home meet in Martin County on a conventional construction loan?
Local building code (verified by county inspections and the certificate of occupancy), plus completion per the plans the appraisal was based on. All improvements must be fully complete before the loan converts — the final inspection and completion report confirm it. Martin County code plus Florida's wind requirements set a genuinely high bar for new construction.
What's the difference between modular and manufactured for conventional loans in Martin County?
Modular homes are built in sections, assembled on-site, and meet the same local building codes as stick-built houses — conventional lending treats them exactly like site-built homes. Manufactured homes are built to the federal HUD code on a permanent chassis and follow their own guideline set with a few extra rules. Both can be financed in Martin County; the paperwork path just differs.
I already own my lot in Martin County — does that help my down payment on a conventional construction loan?
Yes, significantly. The equity in your land counts toward your down payment on a conventional construction loan. And if you've owned the lot for 12 months or more before closing, Fannie Mae lets the loan be based on the as-completed appraised value rather than your cost — which often means little to no cash needed at closing on a Martin County build.
Can I make change orders once construction starts in Martin County on a conventional construction loan?
Yes, but with discipline. Change orders must be documented, priced, and approved — and if they raise the cost, the increase generally comes from contingency or your pocket, since the loan amount was set at closing. Small Martin County changes are routine; a mid-build redesign is not. Decide the big things before you close.
Can a builder use this program for a spec home in Martin County on a conventional construction loan?
No — spec building isn't allowed. The program finances owner-occupied primary residences and second homes for the person who will own them. Builders benefit differently: a committed buyer, verified draws, and no construction-lending risk on their own books. In Martin County — including around Hobe Sound and Indiantown — the same guideline applies.
How do construction draws work in Martin County on a conventional construction loan?
Your builder completes a stage — foundation, framing, dry-in — and requests a draw. An inspector verifies the work is actually done, then funds are released for that stage. It repeats through completion. The draw schedule is agreed before closing, so everyone on your Martin County build knows exactly when money moves.
I've owned my land over a year in Martin County — does that change my conventional loan?
It can, meaningfully. When you've owned the lot 12+ months before closing, Fannie Mae allows the loan to be based on the as-completed appraised value rather than your actual cost. If Martin County land values have risen since you bought — and around Hobe Sound they often have — that appreciation works like extra down payment you never wrote a check for.
Do I have to own land before applying for a conventional construction loan in Martin County?
No — the land purchase can be part of the same loan. If you've found a Martin County lot near Palm City or Port Salerno, the single-close can buy it and fund the build in one transaction. Already own land? Even smoother — your equity goes to work as down payment.
What if my credit score drops during construction in Martin County on a conventional construction loan?
If requalification is triggered, a lower score can affect your permanent terms — which is exactly why we coach you to protect your credit from closing day to completion. Steady credit in, locked terms out. In Martin County — including around Hobe Sound and Indiantown — the same guideline applies.
How is a home that doesn't exist yet appraised in Martin County on a conventional construction loan?
From the plans. The appraiser reviews your blueprints, specifications, and cost breakdown, then values the home 'subject to completion' using comparable finished sales in Martin County. That as-completed value is what the loan is built on. A final inspection after construction confirms the home matches what was appraised.
When does my first full mortgage payment start in Martin County on a conventional construction loan?
After the home is complete and the loan converts to permanent financing. During the build you're typically paying interest only on drawn funds; once your Martin County home gets its certificate of occupancy and the conversion happens, regular principal-and-interest payments begin — usually the first of the month after conversion.
Can I act as my own general contractor on a conventional build in Martin County?
Generally no — conventional construction programs require a licensed, registered general contractor to run the build. Self-builds add risk that most investors won't purchase. If you're a licensed GC yourself building your own home, ask us — limited exceptions exist. Otherwise, hire a registered Martin County builder and stay involved as the owner.
Who is my point of contact during the build in Martin County on a conventional construction loan?
During construction, the loan-administration team is your builder's direct contact for draws and inspections, while our team stays with you on everything else — timeline, credit protection, and the modification at the end. You're never guessing who to call. In Martin County — including around Hobe Sound and Indiantown — the same guideline applies.
What does a turnkey contract actually mean in Martin County on a conventional construction loan?
It means the builder is responsible for everything — the home, all site work, all improvements — delivered complete for one contracted price. You're not left coordinating subs or finishing items yourself. Turn the key, move in. In Martin County — including around Palm City and Port Salerno — the same guideline applies.
Is my financing protected during the months of construction in Martin County on a conventional construction loan?
Yes — that's the core advantage of a One-Time Close. Your permanent loan terms are established at closing, before ground breaks, and they carry through the entire build. Whatever the market does over the following months, your Martin County financing is already settled. Two-close structures can't promise that.
How does a conventional construction loan work from start to finish in Martin County?
Pre-approval sizes your budget. You choose land and a builder, we register the builder, the appraiser values the plans, and you close once — permanent terms set. Construction runs on inspected draws for roughly 6–12 months. At completion: final inspection, certificate of occupancy, automatic conversion, move in. One loan carries the entire Martin County journey.
Who pays for cost overruns during construction in Martin County on a conventional construction loan?
It depends on your contract and the cause. A fixed-price (turnkey) contract puts most overrun risk on the builder; a cost-plus contract leaves it with you. The contingency reserve inside the loan absorbs the first layer either way. This is why we push Martin County clients toward fixed-price contracts with a healthy contingency — the risk is decided before it happens.
Can I build a manufactured home with a conventional construction loan in Martin County?
Yes. A new manufactured home that has never been attached to a foundation can be financed with a conventional construction-to-permanent loan, covering the home purchase, foundation, and site work. Fannie Mae's MH Advantage program even allows up to 97% financing on qualifying homes. Underwriting must run through the automated systems, and we handle that on Martin County placements.
Can well, septic, and driveway costs be financed in the conventional loan in Martin County?
Yes — site preparation is an eligible use of construction funds, and that includes the well, septic system, driveway, utility runs, clearing, and grading. Rural Martin County parcels outside Stuart often need all of it, and it all rides inside the one loan with the rest of your budget.
Fees, Money & Timing8 Q
How does the construction term affect my cash to close in Martin County on a conventional construction loan?
Directly — the term drives the interest and soft-cost figures built into the transaction, so a 12-month selection costs more upfront than a 6-month one. We size the term to your builder's actual schedule, not a guess. In Martin County — including around Palm City and Port Salerno — the same guideline applies.
What closing costs come with a conventional construction loan in Martin County?
The usual suspects — origination, appraisal, title, recording, prepaid taxes and insurance — plus construction-specific items like draw inspection fees and the slightly higher appraisal cost for plan review. The single-close advantage: you pay this once, not twice. Builder contributions can offset a chunk of it on Martin County contracts.
How are builder deposits handled on a conventional build in Martin County?
Deposits you've paid the builder for plans or to reserve a slot are documented and credited to you within the transaction — they're part of your investment in the project, not lost money. Keep every receipt. Large deposits before loan approval carry risk, though: on a Martin County custom build, keep pre-closing deposits modest until financing is locked.
Are escrows collected at closing in Martin County on a conventional construction loan?
Yes — escrows are collected at the initial closing, with homeowner's insurance activated and paid at modification. Taxes that come due during the build are handled by you directly until the escrow account takes over. In Martin County — including around Hobe Sound and Indiantown — the same guideline applies.
How long does approval take for a conventional construction loan in Martin County?
Pre-approval: usually a day or two. Full approval through closing: commonly 30–45 days once your builder's package and plans are complete, since the appraisal reviews the full plan set. The critical path is almost always builder paperwork, not your file — which is why we start the Martin County builder registration on day one.
How do property taxes and insurance work during construction in Martin County on a conventional construction loan?
During the build you'll typically carry a builder's-risk insurance policy (often through the builder) and pay taxes on the land value only. At conversion, standard homeowner's insurance takes over and the escrow account begins collecting for Martin County taxes and premiums with your regular payment. We line up the insurance handoff so there's never a coverage gap.
Can gift funds cover my down payment on a conventional loan in Martin County?
Yes — gifts from family members can cover the entire down payment and closing costs on a primary residence, with a simple gift letter and paper trail. Combine a cash gift with gifted or discounted family land and a Martin County build can launch with remarkably little of your own savings.
Who pays for the appraisal and draw inspections in Martin County on a conventional construction loan?
The borrower, as with any loan — the plan-review appraisal runs somewhat above a standard appraisal, and each draw inspection carries a modest fee, all disclosed up front on your estimate. Some builders absorb inspection costs in the contract. No surprises: every Martin County fee is on paper before you commit.
Process, Docs & Underwriting7 Q
What actually happens at a conventional construction loan closing in Martin County?
You sign the permanent note and mortgage with a construction addendum, the land is purchased or refinanced, initial funds position for the first draw, and title records the lender in first place. From that moment your terms are set and your builder is cleared to pull permits. It's one sitting — Martin County families are usually done within the hour.
Can I switch lenders mid-process and keep my appraisal in Martin County on a conventional construction loan?
No — appraisal transfers aren't accepted on this program; the as-completed appraisal is ordered fresh with the finalized contract and plans. If you're unhappy where you are, the restart is smaller than it feels. We'll show you the real timeline. In Martin County — including around Hobe Sound and Indiantown — the same guideline applies.
What are lien waivers and why do they matter on my build in Martin County on a conventional construction loan?
Every draw, your builder signs a waiver confirming subcontractors and suppliers are paid for that stage — so nobody can later slap a lien on your Martin County home for a bill the builder skipped. Florida's construction lien law makes this protection essential. The draw process collects waivers automatically; it's the paperwork that guards your title.
What is the final inspection and completion certification in Martin County on a conventional construction loan?
After the certificate of occupancy, the appraiser (or an approved inspector) issues a completion report confirming the home was built to the plans the value was based on. That report is the trigger for conversion to permanent financing. It's the last checkpoint of your Martin County build — and the moment the project officially becomes your home loan.
What documents do I need to apply for a conventional construction loan in Martin County?
Your side: pay stubs, W-2s or two years of tax returns if self-employed, bank statements, and ID. The project side: builder contract, plans and specs, cost breakdown, and land documentation (deed or purchase contract). We split the list cleanly between you and your Martin County builder so nobody duplicates effort.
What is the project calculation and why does it come first in Martin County on a conventional construction loan?
It's the structured math of your entire deal — contract price, land, soft costs, interest, and term — run before underwriting so your loan amount and cash-to-close are right the first time. Deals structured correctly upfront don't blow up at the closing table. In Martin County — including around Hobe Sound and Indiantown — the same guideline applies.
Is my conventional construction loan a purchase or a refinance in Martin County?
It hinges on land ownership at closing: if you're acquiring the lot in the transaction, it's processed as a purchase; if you already own the Martin County land, it's structured as a refinance that pays off any lot lien and funds construction. Same single-close experience either way — the classification mainly steers which guideline set and contribution rules apply.
Comparisons5 Q
Conventional vs FHA construction loan in Martin County — which fits me?
FHA takes 3.5% down with flexible credit but carries mortgage insurance that typically lasts the life of the loan. Conventional starts at 3–5% down, allows second homes and investment builds, and its PMI cancels as equity grows. Stronger credit and any land equity usually tip the math conventional in Martin County. We price both side by side and let the numbers decide.
New conventional construction loan vs HomeStyle Renovation in Martin County — which do I need?
Ground-up on vacant land is construction-to-permanent territory. Buying or owning an existing Martin County home that needs transformation — additions, gut remodel, hurricane hardening — is HomeStyle Renovation, one loan covering purchase-plus-rehab on the after-improved value. Tear-down-and-rebuild scenarios can go either way; we structure whichever fits the project.
Conventional vs USDA construction loan in Martin County — how do I choose?
USDA One-Time Close offers $0 down but requires an eligible rural address and household income under the county limit. Conventional works at any Martin County address with no income cap, allows second homes and investments, and its PMI cancels. Rural site plus moderate income? USDA is hard to beat. Otherwise conventional carries the day. Dual-eligible families should see both priced together.
Conventional vs VA construction — what's the difference in Martin County?
VA is exclusively for eligible veterans and service members: $0 down and no monthly mortgage insurance, an unbeatable combination when it applies. Conventional is open to everyone and adds second-home and investment builds VA doesn't cover. Veterans in Martin County should almost always look at VA first — and we'll show conventional beside it so the choice is proven, not assumed.
What happens if my project cost exceeds the conforming limit in Martin County on a conventional construction loan?
Above $832,750 (the 2026 one-unit limit in Martin County), the loan becomes jumbo construction — still very financeable, with larger down payments and full-documentation underwriting. Sometimes trimming the budget under the limit or applying more land equity keeps you conforming. We model both structures so you choose with the full picture.
