Nine construction loan myths debunked with agency sources: FHA 3.5% down, VA and USDA $0 down, draw schedules, rate float, and owner-builder rules in Colorado Springs.
Construction Loan Requirements: Credit, DTI, Reserves, and Your Builder
A construction loan gets underwritten twice: once for you and once for your builder. On the borrower side, lenders check the same pillars as any mortgage — credit score, debt-to-income (DTI), assets and reserves, and documentation — but they hold you to a tighter standard because they are lending against a house that does not exist yet. On the builder side, they verify licensing, references, a fixed-price contract with real start and end dates, and a draw schedule that matches the plans. Clear both underwrites and you can convert to a permanent mortgage when the certificate of occupancy is issued. This guide walks through exactly what each side has to prove, with the agency rules that set the floor.
If you are still deciding whether to build at all, start with our overview of construction loans in Colorado and the side-by-side comparison of FHA, VA, USDA, and conventional construction loans. This page is the requirements deep-dive that sits underneath both.
The borrower underwrite: credit, DTI, reserves, and documentation
Everything a lender asks of you falls into four buckets. Each program sets a floor, and the individual lender can layer stricter “overlays” on top — construction financing is exactly the kind of higher-risk product where overlays are common.
Credit score: program floors and lender overlays
Each loan program publishes a minimum, but almost every lender sets its own construction-loan overlay above it. Here is where the agency floors currently sit (general — confirm current):
- FHA: Per HUD Handbook 4000.1, a minimum decision credit score of 580 qualifies for maximum financing at 3.5% down. Scores of 500–579 are limited to 90% loan-to-value (a 10% down payment), and borrowers below 500 are not eligible for FHA-insured financing. See our FHA construction loan page for how this maps to a one-time-close build.
- Conventional (Fannie Mae): Loans run through Desktop Underwriter no longer carry a stated minimum representative credit score — DU evaluates the full risk profile. Manually underwritten conventional loans still require 620 for fixed-rate and 640 for ARMs. In practice, most lenders want a mid-600s-plus score for a conventional construction loan.
- VA: The VA sets no minimum credit score; lenders impose their own, frequently in the low-to-mid 600s. Details on our VA construction loan page.
- USDA: No hard agency floor, but a 640 score generally unlocks the streamlined automated underwriting path most lenders use for the USDA construction loan.
Our take: treat the published minimum as the entry ticket, not the target. On a build, lenders are pricing risk on an unfinished asset, so a stronger score does more for your rate and your approval odds here than it would on a standard purchase.
Debt-to-income: the same ratios, less room to stretch
DTI on a construction loan is measured the same way as on any mortgage: your total monthly debt payments divided by your gross monthly income, using the projected PITIA (principal, interest, taxes, insurance, and any association dues) of the finished home. Conventional loans commonly stretch to around 45%, and up to roughly 50% with strong compensating factors; FHA and VA can go higher with automated approval and offsetting strengths. Those are general benchmarks — confirm current — and underwriters have less appetite to push the ceiling on a build than on a completed home.
Because the qualifying payment is based on the finished home’s value and taxes — not the raw land — it is worth pinning down your number before you fall in love with a floor plan. Run it through our home affordability calculator so the contract you sign with a builder lines up with the payment you can actually carry.
Reserves and assets: where construction loans get stricter
Reserves — liquid money left over after your down payment and closing costs, measured in months of PITIA — matter more on a construction loan than on almost any other mortgage. The reasons are structural, not arbitrary:
- Timeline risk. Builds slip. A delayed certificate of occupancy, a weather stoppage on the Front Range, or a subcontractor backlog can extend the schedule, and the lender wants to see you can absorb the carrying cost.
- Cost-overrun risk. Material and labor surprises are common. Reserves (alongside a contingency line in the budget) are the cushion that keeps a $15,000 overage from stalling the project.
- Dual-carry risk. Many borrowers pay rent or an existing mortgage while the new home goes up. Lenders test whether you can carry both.
Expect a construction lender to ask for more months of reserves than a comparable purchase would, and to document every dollar with the same rigor as your down payment. How much cash you bring up front is its own subject — we cover it in depth on the construction loan down payment page. The key point: the borrower generally has to contribute their own down-payment funds and show them seasoned in the bank; the lender does not simply advance 100% of the budget on most programs.
Documentation: proving income, assets, and the deal
The paperwork mirrors a standard mortgage plus a construction layer. On the personal side you will provide recent pay stubs, two years of W-2s or tax returns (more if self-employed), and bank and asset statements covering the down payment and reserves. On the project side you will add the construction contract, budget, plans and specifications, and the builder’s documentation described below. Fannie Mae requires credit documents to be no more than four months old on the note date, so if your build stretches out, expect to refresh paperwork before the loan converts to permanent financing.
The builder underwrite: a second approval most borrowers overlook
This is the part that surprises first-time builders. Your lender underwrites the general contractor almost as carefully as it underwrites you, because a bankrupt or unlicensed builder is the fastest way for a half-built house to become a bad loan. Expect the following to be verified.
Licensing and standing
The builder must hold any state and local licenses their work requires. This did not go away when the VA simplified its process: effective in 2025, VA Circular 26-25-1 rescinded the VA-issued builder identification number for most guaranteed construction loans, but the circular is explicit that builders “must still meet any applicable state and/or local licensing requirements.” Colorado does not license general residential builders at the state level, so in El Paso County and Colorado Springs licensing is handled locally through the applicable building department and permit process — your lender will still want proof the builder is in good standing.
Experience and references
Lenders want a track record. USDA is the most prescriptive here: under HB-1-3555 Chapter 12, a builder on a single-close (combination construction-to-permanent) loan must have two or more years of experience building all aspects of single-family dwellings similar to the proposed project, an acceptable credit history free of judgments, collections, or liens related to prior construction, and evidence of commercial general liability insurance with minimum coverage of $500,000. Owner-builders and self-contracting borrowers are not eligible under the USDA single-close program. Even on programs that do not spell those numbers out, underwriters ask for a résumé of completed homes and references you can call.
A fixed-price contract with start and end dates
The construction contract is a core underwriting document. Lenders strongly prefer a fixed-price (or guaranteed-maximum-price) contract over an open-ended cost-plus arrangement, and it must include a defined scope, a total price, and firm start and completion dates. Those dates are not decoration — Fannie Mae limits a single-closing construction-to-permanent loan to no single construction period longer than 12 months and a total period not exceeding 18 months, so the schedule in your contract has to fit inside the program’s window.
A realistic draw schedule
The lender releases money in stages tied to completed work — the draw schedule — rather than in one lump sum. It must map logically to the build (foundation, framing, rough-ins, drywall, finishes, completion), usually with inspections before each release. If you want the mechanics, our guide to how construction loan draws work breaks the process down step by step. A draw schedule that front-loads too much money or does not match the plans is a red flag underwriters routinely reject.
How the requirements differ by loan structure
Requirements also shift depending on whether you choose a one-time-close (single closing) or a two-time-close (two closings) structure. The single-close converts automatically to a permanent mortgage; the two-close treats the permanent phase as a separate loan. Notably, Freddie Mac’s rules — updated for applications received on or after February 4, 2026 — require the permanent financing in a two-time-close transaction to be classified as a refinance (no-cash-out or cash-out), not a purchase. That classification affects seasoning and documentation on the back end. We compare the two paths in detail on the one-time-close vs. two-time-close page.
| Requirement | Borrower side | Builder side |
|---|---|---|
| Credit | Program floor + lender overlay (FHA 580, conventional 620 manual) | Clean credit history; USDA requires no construction-related liens/judgments |
| Capacity | DTI within program limits on finished-home PITIA | 2+ years relevant experience (USDA); track record and references |
| Cash / risk cushion | Own-funds down payment + reserves in months of PITIA | $500,000 general liability insurance (USDA); bonding varies |
| Documentation | Income, assets, statements (credit docs <4 months old at note date) | License, fixed-price contract, plans, draw schedule |
Getting your file construction-ready in Colorado Springs
The borrowers who close smoothly are the ones who prepare both underwrites in parallel. Pull your credit early and address any drag on your score; document your down payment and reserves and let them season; and choose a builder who can hand your lender a clean package — license, insurance, references, a fixed-price contract, and a sane draw schedule — without being chased for it. Around Colorado Springs, Fort Carson, and the wider El Paso County market, we see the same avoidable delays repeat: a builder who cannot produce insurance certificates, or a contract with vague completion dates that will not fit inside the program’s construction window.
As a local broker, we can shop your file across multiple construction-loan investors and match your credit, DTI, and reserves to the program with the friendliest overlays. If you are ready to map your specific numbers to a real program, talk to our team through the Colorado Springs mortgage broker page — bring your rough budget and timeline and we will tell you what each side of the underwrite will need.
Frequently asked questions
What credit score do I need for a construction loan? It depends on the program, and lenders usually add overlays on top. FHA’s floor is 580 for 3.5% down (500–579 requires 10% down) per HUD Handbook 4000.1; manually underwritten conventional loans require 620 fixed-rate or 640 ARM, while Fannie Mae’s Desktop Underwriter no longer states a minimum. VA and USDA set no hard agency minimum, but most lenders want the low-to-mid 600s. These are general figures — confirm current.
Why do construction loans require more reserves than a regular mortgage? Because the lender is financing an asset that does not exist yet. Reserves — measured in months of PITIA — cover the risk of construction delays, cost overruns, and carrying both your current housing payment and the new one during the build. Expect a construction lender to ask for more months of reserves than a comparable purchase.
Does my builder have to be approved too? Yes. The lender underwrites your builder for licensing, experience, references, insurance, a fixed-price contract, and a workable draw schedule. USDA HB-1-3555 Chapter 12, for example, requires two-plus years of relevant experience, a clean construction credit history, and at least $500,000 in commercial general liability insurance, and does not allow owner-builders. The VA rescinded its builder identification number in 2025, but builders must still meet all state and local licensing rules.
Do I still need to make a down payment on a construction loan? Generally yes. The borrower usually has to contribute their own down-payment funds, documented and seasoned, rather than the lender advancing the full budget. VA and USDA offer zero-down permanent financing for eligible borrowers, but program and lender rules still govern how much equity or cash you bring to the construction phase. See our construction loan down payment page for specifics.
How is DTI calculated on a construction loan? The same way as any mortgage — total monthly debt divided by gross monthly income — but the housing payment used is the projected PITIA of the finished home, not the cost of the land. Conventional loans commonly allow around 45% (up to roughly 50% with strong compensating factors); FHA and VA can go higher with automated approval. Confirm current limits with your lender.
What documents does the builder have to provide? Typically a current license, proof of general liability insurance, a résumé of completed projects with references, a fixed-price construction contract with start and completion dates, full plans and specifications, a line-item budget, and a draw schedule tied to construction milestones.
