Conventional construction loan credit requirements

Conventional financing generally weighs credit more heavily than FHA — your score, history, and debt-to-income shape both approval and pricing. This page covers how credit is generally evaluated for a conventional one-time-close construction loan, including the single-close requalification nuance. Final eligibility is determined by automated underwriting review.

The Big Picture

Automated underwriting reads the whole file

Conventional construction loans generally run through Fannie Mae's automated underwriting, which evaluates your complete financial picture rather than a single number — income stability, assets, equity, reserves, and credit together. A published score floor exists, but what actually qualifies a file is the automated finding on the whole picture. Reviewed by Jim Blackburn, NMLS #1072866.

How It's Evaluated

Score, tiers, and the single-close nuance

A conventional credit review generally weighs several things together:

Score floor and tiers

The published floor for manual underwriting is generally 620. Above it, higher score bands typically improve mortgage-insurance and pricing tiers — so credit affects not just approval but cost. Final eligibility is determined by underwriting.

The single-close requalification nuance

You qualify once, up front. As a general guideline, a representative score of 700 or higher typically waives requalification at completion, while a score in the 680–699 band may prompt a credit refresh. The lender's guidelines govern the final call.

Debt-to-income

An automated approval can allow a higher debt-to-income ratio than a manual file — but the figure that actually qualifies depends on the strength of the overall picture, and you're qualified on the full future construction-to-permanent payment.

Protecting credit during the build

Because a lower score can matter if requalification is triggered, keeping your credit steady from closing to completion helps protect your permanent terms. Steady credit in, locked terms out.

Past Events

Bankruptcy and foreclosure have waiting-period guidelines

A past bankruptcy or foreclosure is generally a waiting period with a defined end date, not a permanent barrier. Under conventional guidelines the general windows are around four years from a Chapter 7 discharge, two years from a Chapter 13 discharge, seven years from a foreclosure, and four years from a deed-in-lieu or short sale — with documented extenuating circumstances sometimes shortening them. The clock has often run longer than people assume, so it's worth confirming your actual dates. Every scenario is reviewed personally by Jim Blackburn, NMLS #1072866, and final eligibility is determined by underwriting.

Common Questions

Credit FAQ

General guidance below reflects typical conventional program parameters. It is educational and not a commitment to lend — your file is evaluated individually by automated underwriting.

What credit score do I need for a conventional loan?
The published floor for manual underwriting is 620, and automated underwriting evaluates the full file rather than a single cutoff. Higher score tiers generally 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 can map a score-building path before your build, not after.
Does the conventional loan use my middle credit score?
The representative score drives the decision — and on a construction loan it can matter twice: a 680 generally gets you approved, and 700 or higher typically waives requalification at completion. If you're sitting around 690, a few months of targeted credit work before closing can simplify your entire build.
Do I have to requalify after construction?
Typically not, if your representative credit score is 700 or higher — requalification is generally waived unless the property value declines or the project runs past 12 months. In the 680–699 band, plan on a credit refresh at completion, and protect your file during the build. These are general single-close guidelines, and the lender's guidelines govern the final call.
What if my credit score drops during construction?
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.
What's the maximum debt-to-income ratio on a conventional loan?
With an automated approval, debt-to-income can reach 50%. Manually underwritten files typically cap at 36–45% depending on compensating factors like reserves and credit. The ratio uses gross income, and on a construction loan you're qualified on the full future payment — so your budget is honest from day one.
Is manual underwriting available on the construction program?
On the construction program, the file generally must have an automated approval through Fannie Mae's Desktop Underwriter — manual underwriting typically isn't available. That makes the pre-qualification run we do upfront genuinely meaningful: the same engine that decides is the one we test.
How long after bankruptcy or foreclosure can I get a conventional loan?
General waiting periods: four years after a Chapter 7 discharge, two years after a Chapter 13 discharge, seven years after a foreclosure, and four after a deed-in-lieu or short sale — with shorter windows possible under documented extenuating circumstances. The clock has usually run longer than people assume; bring us the dates and we'll tell you where you stand.
Is a conventional loan only for people with perfect credit?
No — that's the most expensive myth in mortgages. Conventional loans start at a 620 credit score, and automated underwriting weighs your whole file: income stability, assets, equity, and reserves. Plenty of buyers with mid-600s scores close conventional every month. Stronger credit improves pricing, but 'perfect' was never the requirement.
