Construction
loan requirements

Overview

This guide covers construction loan requirements — including how these programs work, what lenders look for, and how to get started. Qualification requirements vary by lender and program type. All loan programs are subject to credit approval and lender-specific criteria.

• Program availability varies by lender
• Qualification requirements vary by scenario
• Multiple program types available
• Speak with a licensed MLO for your situation

Borrower requirements, quantified

• Credit: most programs want 680+, with 700–720+ common at jumbo scale and for the best structures; construction adds project risk, so credit floors sit above equivalent purchase-mortgage floors.
• Down payment / equity: typically 10–20% of total project cost (land + build) for owner-occupied homes, 20–30% at jumbo scale or for second homes. Land you already own counts at its appraised value — longtime lot owners often satisfy the entire requirement with equity.
• Debt-to-income: qualified against the full eventual payment (principal, interest, taxes, insurance on the completed home), generally capped in the low-to-mid 40s.
• Reserves: post-closing liquidity beyond the down payment — commonly 6–12 months of the eventual payment, more on large builds.
• Income documentation: full doc is the norm; bank-statement construction programs exist but are a placement specialty.

Nothing here is exotic — it is purchase-mortgage underwriting with a stress premium.

Project and builder requirements

• Complete architectural plans — schematic drawings don't underwrite; construction sets do.
• Line-item budget with fixed-cost contract — cost-plus contracts are fundable at some lenders but underwrite harder; open allowances draw scrutiny.
• Contingency reserve of 5–10% inside the approved budget.
• Licensed, insured builder with references and financial statements — lenders decline builders more often than borrowers realize, so vet yours against lender standards early.
• Buildable lot with clear title, and survey/soil work where the site demands it.
• "Subject-to" appraisal supporting the completed value — the build must pencil, not just the borrower.

A project can fail requirements a borrower passes, and vice versa; both files must clear.

Requirements that vary most between lenders

The published basics above are table stakes — the requirements that actually differentiate lenders are quieter: maximum loan-to-cost versus loan-to-value (and which binds), owner-builder tolerance, treatment of sweat equity, rural and acreage appetite, construction-period length and extension terms, and jumbo capacity. Two lenders can both "offer construction loans" and be unrecognizable on these axes. Matching your project's specific shape to the lender whose requirements it already satisfies — rather than reshaping the project — is the entire value of shopping this market through a broker.

Quick answers

Do requirements loosen for smaller builds?

Documentation stays similar; leverage and reserve expectations ease somewhat at modest budgets. The builder and plans requirements are scale-independent.

Can requirements be met with a co-borrower?

Income, credit, and reserves pool the same as any mortgage — a strong co-borrower rescues many construction files. All parties sign for the full project.

How current must my documents be at closing?

Standard freshness rules apply — pay stubs within 30 days, statements within 60, credit within 120. Long approval-to-closing gaps mean refreshing paperwork; plan for it.
