What Is a Construction Loan?

Mortgage explanations and FAQs by Michael George.

An Arizona construction loan pays your builder in stages as your home takes shape, then converts to a regular mortgage — one application, one closing. Unlike a purchase mortgage that hands you a lump sum at closing, a construction loan holds the money in escrow and releases it in draws as milestones are completed — covering the land, labor, materials, and permits.

The one-time close version — sometimes called construction-to-permanent or single-close — combines the construction loan and the permanent mortgage into a single closing before the first shovel hits dirt. You underwrite once, pay one set of closing costs, and when the final inspection clears, the same loan simply becomes your home mortgage: no second application, no requalifying with your income mid-build. During construction, you typically pay interest only on the money actually disbursed so far, so payments start small and grow as the house does — though a few lenders charge interest on the full commitment, so ask how yours is structured.

What Are the Requirements for a Construction Loan?

Every loan type plays by its own rulebook, and the difference between a government rule and a lender's requirement matters. FHA allows 3.5%-down financing at a 580 credit score — scores from 500 to 579 can still build with 10% down, and nothing below 500 qualifies. VA sets no minimum credit score at all, requires no down payment, and charges no monthly mortgage insurance; a one-time funding fee takes its place. USDA has no credit-score floor either, though 640 is the threshold its automated underwriting system uses, with manual underwriting available below it. Conventional one-time close loans start at 5% down for a one-unit primary residence under Fannie Mae and Freddie Mac rules, with agency score floors down to 620. Lenders routinely stack their own higher minimums on top of all of these — when you compare offers, ask where the agency rule ends and the lender overlay begins.

Prefer to hear it from the source? USDA Rural Development — the agency that runs the Single Close program — published an 11-minute training walking through its new-construction requirements. Fair warning: USDA recorded it for lenders and industry partners, so it runs more technical than a typical homebuyer video. It is also about as authoritative as a single-close walkthrough gets.

Draws, Inspections, and Who Holds the Money

FHA and USDA both require construction proceeds to sit in an escrow account, released only against completed work. Each draw needs documentation — evidence of a third-party inspection and, at USDA, additional per-draw paperwork such as lien waivers and title updates — plus your written authorization before the money moves. That inspection rhythm is the quiet superpower of construction lending: your builder does not get paid for stage two until stage one actually passes. The stage-by-stage split in the draw schedule below is the typical shape of a draw schedule, not a regulation — every lender's percentages differ a little.

Locking Your Rate

With a one-time close, your permanent rate is set at closing, months before the house is done. FHA requires your lender to document exactly where the lock-in happens, cap the maximum rate your mortgage can convert to, and let you lock lower if rates fall during construction. USDA establishes the permanent rate at the closing itself, and Fannie Mae underwrites the whole package on the permanent loan's terms. If rates drop mid-build, that structure works in your favor.

Land You Already Own, and the As-Completed Appraisal

Already own your lot? Its equity counts toward your down payment — FHA lets land equity satisfy its minimum investment, valuing land you have held for more than six months at full appraised value and newer purchases at the lesser of what you paid or what the land appraises for. Before construction starts, the lender orders an "as-completed" appraisal: the projected value of the finished home on its lot. That number — not today's dirt — determines how much you can borrow.

Timelines, Honestly

Federal data set the honest baseline: single-family homes completed in 2025 took about 8.8 months from authorization to completion on average — roughly 7.5 months for homes built for sale, nearly 12 for contractor-built customs, and closer to 14.5 months when owners manage the build themselves. Approval timing has no official standard, but because a one-time close underwrites the full package up front, budgeting 30 to 60 days before groundbreaking is a reasonable planning range. Most builders and lenders also plan a contingency reserve — commonly 10–20% of the budget — for overruns. It is a best practice rather than a government requirement, and USDA expressly allows financing it into the loan.

None of this is meant to scare you off — most builds go exactly this way. But going in clear-eyed about the money mechanics is the difference between a fun project and a stressful one. If you want a straight answer about whether building fits your timeline and budget, call us. If buying existing turns out to be the better fit, we will tell you that too.

*Credit scores shown are agency floors — the government minimums. VA and USDA set no minimum; USDA's 640 is the threshold for its automated underwriting system, with manual underwriting available below it. Individual lenders (including us) often require higher minimums — ask any lender where the agency rule ends and the overlay begins.

All four are available as one-time close construction-to-permanent loans in Arizona.

Which Should You Choose?

Veterans: VA construction loans require no down payment and no monthly mortgage insurance — a one-time funding fee applies. Rural builders: USDA's Single Close program offers 0% down in eligible areas, with no credit-score minimum set by USDA. Everyone else: FHA allows 3.5% down at a 580 score (500–579 requires 10% down), and conventional financing starts as low as 5% down for strong profiles.

Common Questions

Frequently Asked Questions

Everything you need to know about Arizona construction loans

How It Works

What is the difference between a construction loan and a traditional mortgage?

A construction loan is usually a short-term loan used to finance the building of a new home, with the money typically held in escrow and released in stages — called draws — as construction progresses. A traditional mortgage is a long-term loan used to purchase an existing home, with the full loan amount provided at closing.

What is a one-time close construction loan?

A one-time close construction loan (also called construction-to-permanent or single-close) combines your construction financing and permanent mortgage into a single transaction that closes before construction begins. You apply once, close once, and pay one set of closing costs. After construction, the loan becomes your permanent mortgage without a second application or requalification.

How long does it take to get approved for a construction loan in Arizona?

There is no official standard — timing varies by lender and project. Because a one-time close underwrites the construction and permanent loan together up front, budgeting roughly 30 to 60 days before construction can begin is a reasonable planning range.

How long does it take to build a house in Arizona?

Federal Census data show new single-family homes took about 8.8 months on average from authorization to completion in 2025 — roughly 7.5 months for homes built for sale, about 12 for contractor-built homes, and closer to 14.5 months when owners manage the build themselves. Monsoon-season weather, materials, and labor can all move your timeline.

What is a draw schedule?

A draw schedule is the timeline for when the lender releases funds to your builder, tied to construction milestones such as foundation, framing, rough-ins, and final completion. FHA and USDA both require documented inspections — and your written authorization — before each draw is disbursed. Every lender splits the percentages a little differently. The series guide to Construction Loan Draws, Inspections, and Rates During the Build walks through a full draw cycle, request to disbursement.

Money, Builders & Timeline

Do I need to own land before applying for a construction loan?

No. Many construction loans finance the land purchase along with the construction costs. If you already own the lot, its equity can count toward your down payment — under FHA rules, land you have owned for more than six months counts at full appraised value, while a more recent purchase counts at the lesser of what you paid or its appraised value.

What happens if construction costs exceed my loan amount?

You cover the difference out of pocket — which is exactly why builders and lenders plan a contingency reserve, commonly 10–20% of the budget, for price increases and change orders. A contingency is a best practice rather than a government requirement; USDA expressly permits financing one as part of the loan.

Can I act as my own general contractor?

It's much harder than it used to be. FHA allows you to act as your own general contractor only if you are a licensed general contractor. USDA's single-close program prohibits owner-builders entirely, and it requires a builder with at least two years of experience, a state license, and $500,000 in general liability insurance.

What is an "as-completed" appraisal?

An "as-completed" appraisal estimates the market value of your finished home on its lot — before construction starts — based on your plans, specifications, and comparable properties. That number determines how much the lender will finance. When the build is done, the lender confirms completion (Fannie Mae lenders use Form 1004D) before the loan converts to your permanent mortgage.

What credit score do I need for a construction loan in Arizona?

Lower than most people think — but individual lenders often set their own higher minimums on top of the agency floors. FHA allows 3.5%-down financing at a 580 score (500–579 requires 10% down; below 500 does not qualify). VA and USDA set no minimum credit score at all — 640 is simply the threshold for USDA's automated underwriting system, with manual underwriting available below it. Conventional agency floors run to 620, and 680+ is a common lender requirement for construction deals. Ask any lender — including us — where the agency rule ends and the lender overlay begins.

Do I make payments during the construction phase?

Typically yes — you pay interest only on the amount disbursed so far, so payments start small and grow as construction progresses. A few lenders instead charge interest on the full commitment from day one, so ask how yours works. Once construction completes and the loan converts, you begin regular principal-and-interest payments. The series guide to Construction Loan Draws, Inspections, and Rates During the Build shows how the monthly number climbs as the house rises.

Can I lock in my interest rate before construction begins?

Yes — with a one-time close, the permanent rate is set at closing, months before the house is finished. FHA requires the lender to document the lock-in point, cap the maximum rate your mortgage can convert to, and permit locking lower if rates fall during construction; USDA establishes the permanent rate at the closing itself.
