# Iowa Construction Loans: How to Finance Home Building

*Last updated October 2026*

Unless you pay cash, a new custom house in Iowa is paid for with a construction loan, not a regular mortgage. This guide explains how draws pay your builder, what interest costs during the build, and how one-close and two-close loans differ. It also covers the conventional, FHA, VA and USDA options for home building. You will see what your lender will ask your builder for and the Iowa lien rules that protect each payment.

**TLDR:** Unless you pay cash, an Iowa custom home is financed with a **construction loan** that pays your builder in draws as work is finished. A one-close loan sets your permanent mortgage terms at the start. A two-close loan means two closings and a new rate at the end. Budget for interest during the build, give your lender time to review builder paperwork, and collect lien waivers with every draw.

---

The question Central Iowa homeowners search most before calling about a new build is what it costs to build a house in Iowa. The next question is harder: how do you pay for a house that does not exist yet?

A regular mortgage lends against a finished home. A construction loan lends against plans, a contract and a lot, then releases money as the walls go up.

Below you will find a sample draw schedule, a simple way to estimate construction interest, and a side-by-side look at loan types and programs. You will also see the documents lenders want from your builder and the Iowa rules behind them.

## How Does a Construction Loan Pay for Home Building?

A construction loan pays for home building in stages, called draws, as each phase is finished. With a single-close loan, the lender manages payments to the builder, contractors and suppliers. When the house is done, the loan converts to a permanent mortgage, according to the [Fannie Mae Selling Guide](https://selling-guide.fanniemae.com/sel/b5-3.1-02/conversion-construction-permanent-financing-single-closing-transactions).

Your loan agreement sets the draw schedule. The sample below ties each draw to a finished stage, so each payment matches work you can see on the lot.

The table shows one way a $400,000 construction loan could be drawn. It uses the national stage shares from the National Association of Home Builders 2024 cost survey and an example interest rate of 7.5 percent. Your lender’s schedule and rate will differ.

Draw Stage finished Draw amount Total drawn Interest per month at 7.5% (example)

1 Site work and foundation (18.1%) $72,400 $72,400 About $450

2 Framing (16.6%) $66,400 $138,800 About $870

3 Exterior finishes (13.4%) $53,600 $192,400 About $1,200

4 Plumbing, electrical and HVAC rough-ins (19.2%) $76,800 $269,200 About $1,680

5 Interior finishes (24.1%) $96,400 $365,600 About $2,290

6 Final steps and other (8.6%) $34,400 $400,000 About $2,500

The pattern is the point: interest is small early because little money is out, then climbs as the house nears move-in. This is planning math, not a quote or a rate offer.

**Pro Tip 1:** Get the draw schedule in writing before you sign either the builder contract or the loan. Make sure both documents describe the same stages.

**Pro Tip 2:** Ask your lender how each draw is checked and what each check costs. Construction inspection and draw fees must be disclosed in the Loan Costs table or on an addendum.

## What Does Interest Cost While Your Home Is Being Built?

Construction interest depends on how your loan charges it. Federal disclosure rules in [Regulation Z, Appendix D](https://www.consumerfinance.gov/rules-policy/regulations/1026/d/) describe two setups. Some loans charge interest only on money actually advanced. Others charge interest on the full loan amount from the start.

For the first setup, the rule lets lenders estimate interest by assuming half the loan is outstanding for the whole build. That rule of thumb gives you a fast planning number. For the second setup, the whole amount counts from day one, which costs more.

The table applies both methods to a 10-month build at example rates. Check current rates with lenders, because these figures are illustrations only.

Construction loan Interest on drawn funds, 6.5% (example) Interest on drawn funds, 7.5% (example) Interest on full amount, 7.5% (example)

$300,000 About $8,100 About $9,400 About $18,800

$400,000 About $10,800 About $12,500 About $25,000

$500,000 About $13,500 About $15,600 About $31,300

How interest accrues can matter more than a quarter point of rate. On a $400,000 loan, the two methods differ by about $12,500 over 10 months at the same rate.

**Pro Tip 3:** Ask every lender whether you pay interest on drawn funds only or on the full commitment. Get the answer in writing.

**Pro Tip 4:** Request Loan Estimates from at least three lenders in the same week. A lender must send a [Loan Estimate within three business days](https://www.consumerfinance.gov/ask-cfpb/what-is-a-loan-estimate-en-1995/) of your application, and every lender uses the same form.

## One-Close or Two-Close: Which Construction Loan Fits?

A one-close loan sets your construction and permanent terms at a single closing before work starts. A two-close loan uses one closing for construction and a second for the permanent mortgage, which can come from a different lender. The right choice depends on how much rate certainty you want and how long the build will take.

Fannie Mae’s rules show the trade-offs clearly. The table compares the two paths using its Selling Guide sections on single-closing and two-closing transactions.

Question One-close (construction-to-permanent) Two-close (construction loan, then mortgage)

How many closings? One, before construction starts Two: one for construction, one when the house is done

When are mortgage terms set? At the first closing At the second closing, at market rates then

Can the permanent lender change? No, it is one loan Yes, the permanent lender can differ

Time limit on construction No single period over 12 months, 18 months total No Fannie Mae construction period limit

If you owned the lot first Loan-to-value uses the as-completed value of lot and house Cash-out at the second closing requires lot title held at least 6 months

Paperwork at the end Completion report, and requalifying if documents age or value falls New loan documents and underwriting for the permanent mortgage

A one-close loan trades flexibility for certainty, while a two-close loan keeps your options open but repeats the closing work. If your build could run long, the 12- and 18-month limits matter.

**Illustrative scenario:** A [Clive](https://busybuildersiowa.com/clive/) couple plans a 2,600-square-foot two-story. At our starting point of about $150 per square foot, construction plans out from about $390,000, plus the lot. They chose a one-close loan to lock their mortgage terms at the start. The build ran about 10 months, inside the 12-month construction period. At completion, the appraiser filed the completion report and the loan converted on schedule.

**Pro Tip 5:** Keep your credit quiet between closing and conversion. Fannie Mae requires fresh income and credit documents at conversion in many cases, and new debt can force requalification.

**Pro Tip 6:** If you already own your lot, bring the deed and purchase papers to the first lender meeting. Lot equity can change your loan-to-value and your cash needs.

## Which Loan Programs Can Finance Home Building in Iowa?

Four program families can finance home building in Iowa: conventional loans, FHA, VA and USDA. Each sets its own down payment rules, but not every lender offers a construction version of each one. Your first call to a lender should confirm which ones it actually closes.

FHA’s construction-to-permanent program is spelled out in [HUD Handbook 4000.1](https://www.hud.gov/hud-partners/single-family-handbook-4000-1). It uses one closing before construction and holds the loan money in an escrow account. The lender needs your written approval before each draw goes to the contractor.

The table summarizes each program’s construction rules from its primary source.

Program Down payment rule Construction rule to know Often fits

Conventional (Fannie Mae) Set by Fannie Mae’s eligibility matrix; your own funds unless 80% LTV or less or approved gifts apply One-close or two-close; liens must be cleared before Fannie Mae buys the loan Strong credit, larger budgets

FHA 3.5% minimum at credit scores of 580 or higher (96.5% maximum LTV) Rate may float in a set range during the build; you qualify at the maximum rate Smaller down payments

VA Often no down payment, as long as the price is not above appraised value Can be used to build a new home; requires a Certificate of Eligibility and that you live in the home Eligible veterans and service members

USDA Rural Development Up to 100% financing for qualified buyers Can be used to build; eligible rural areas only, with income up to 115% of the area median Eligible rural lots

The [VA says its purchase loans](https://www.va.gov/housing-assistance/home-loans/loan-types/purchase-loan/) can help eligible veterans buy, build or improve a home. Program rules are minimums, and individual lenders can add their own credit, reserve and builder requirements on top.

FHA also counts land you already own. If you have owned the lot more than six months when your case number is assigned, the handbook values it at its appraised value. That equity can satisfy your required investment.

**Illustrative scenario:** A couple who has owned a [Boone County](https://busybuildersiowa.com/boone-county-iowa/) acreage for several years plans a 2,000-square-foot ranch. Construction plans out from about $300,000 at our starting point. They chose an FHA construction-to-permanent loan, and because the land counts at appraised value, their lot equity covered the required investment. They put their cash into a contingency instead and broke ground in spring after a winter of lender review.

**Pro Tip 7:** For an FHA construction loan, ask for the interest rate range during construction and the maximum permanent rate in writing. You qualify at that maximum.

**Pro Tip 8:** Ask each lender which programs it closes as construction loans, not just as purchase loans. The answer narrows your list fast.

## What Will Your Lender Ask Your Builder For?

Your lender will ask your builder for a signed contract with the price to build and an itemized list of extras. It also needs plans complete enough to appraise. At the end, it needs proof the house is finished and free of liens. Homeowners often search for what a general contractor actually does before they call. Assembling this lender package is a big part of that answer.

Busy Builders is a registered Iowa contractor (DIAL registration C140184), based in West Des Moines. Iowa law requires anyone who earns $2,000 or more a year from construction to register with the state, and the registry is public.

The table lists what a construction lender typically requests from the builder side, and the rule behind each item.

Lender asks for Why it matters Rule behind it

Signed contract with the price to build Sets the loan amount and the draw total HUD Handbook 4000.1, construction-to-permanent

Itemized borrower-paid options Shows extras and how you paid for them HUD Handbook 4000.1

Plans and specifications Supports the “as completed” appraisal Fannie Mae B5-3.1-02

Proof of lot ownership or purchase You must hold title to the lot Fannie Mae B5-3.1-01

Lien waivers with each draw Keeps the title clear as money moves Iowa Code 572.13A owner notice

Completion report and certificate of occupancy Confirms the house is finished before conversion Fannie Mae B5-3.1-01 and HUD Handbook 4000.1

None of these items is unusual. Delays come when they arrive late, so ask your builder to prepare the package while you shop lenders.

Iowa adds its own payment protection. Under [Iowa Code section 572.13A](https://www.legis.iowa.gov/docs/code/572.13A.pdf), a general contractor must post a notice of commencement within 10 days of starting work. It goes on the state’s Mechanics’ Notice and Lien Registry. Subcontractors and suppliers then post their own notices. The state’s owner notice tells you to check the registry and collect lien waivers before you pay your general contractor.

Iowa Code 572.30 also sets a payment clock. Unless the contract says otherwise, a general contractor must pay subs in full within 30 days of the owner’s full payment. Our guide to [what a general contractor actually does](https://busybuildersiowa.com/what-a-general-contractor-does-central-iowa/) covers how that coordination works day to day.

**Illustrative scenario:** A [Johnston](https://busybuildersiowa.com/johnston/) family builds with a $420,000 construction loan over about 11 months. Before the framing draw, they checked the lien registry and found a preliminary notice from the lumber supplier. The draw package included a lien waiver from that supplier, so the payment went out the same week. The title stayed clean through conversion.

**Pro Tip 9:** Look up your property on the Mechanics’ Notice and Lien Registry before you approve each draw. Every supplier who posted a notice should have a matching waiver.

**Pro Tip 10:** Check your builder’s state registration before you sign anything. The Iowa Department of Inspections, Appeals, and Licensing keeps the contractor registry public.

**Pro Tip 11:** Set realistic finish allowances up front. On a one-close loan, Fannie Mae allows a higher loan amount only to cover documented increases in construction cost.

**Pro Tip 12:** Plan for the finish line, not just the start. The completion report, certificate of occupancy and a clean title all come at the end, and your lender needs each one.

## Frequently Asked Questions

**Q1: Which financing options are available specifically for building a home in Iowa?** The main options are a one-close construction-to-permanent loan or a two-close construction loan followed by a mortgage. Each can come in conventional, FHA, VA or USDA versions, depending on the lender. If you already own your lot, its equity may count toward your down payment. Ask lenders which construction programs they actually close before you apply.

**Q2: How much down payment do I need for a home building loan?** It depends on the program. FHA requires 3.5% at credit scores of 580 or higher. VA loans often need no down payment, and USDA offers up to 100% financing for qualified rural buyers. Conventional loans follow Fannie Mae’s eligibility matrix. Lot equity can reduce the cash you bring, so get a Loan Estimate that shows it.

**Q3: How long can the construction phase of a loan last?** For a one-close loan Fannie Mae will buy, no single construction period can exceed 12 months, and the total cannot exceed 18. Two-close loans do not carry that Fannie Mae limit. On an FHA loan, permanent payments must begin by the first of the month after 60 days from the final inspection or certificate of occupancy. Ask your builder for a realistic schedule before you choose a loan type.

**Q4: Can I be my own general contractor with a construction loan in Iowa?** FHA allows it only if the borrower is a general contractor by trade. Conventional lenders set their own owner-builder rules. Iowa law also requires an owner-builder who hires subcontractors to post a notice of commencement to the lien registry. Ask lenders about owner-builder rules before you buy a lot.

**Q5: What happens if my home costs more than the construction loan?** You usually cover the gap from your own funds or by cutting scope. On a one-close loan, Fannie Mae allows a loan increase only for documented increases in construction cost, through a modification at or before conversion. That can mean re-underwriting your loan. Build a contingency into your budget before you close.

**Q6: Do I need a new appraisal when the house is finished?** On a one-close conventional loan, the appraiser completes a completion report when construction ends. If the value has dropped, the lender must order a new appraisal and requalify you. FHA loans need a final inspection or certificate of occupancy before the loan can be insured. Keep your builder’s final paperwork moving so conversion is not delayed.

## Key Takeaways

- **Draws pay the builder:** Money is released in stages as work is finished, and your interest grows as more is drawn.
- **Know how interest accrues:** Interest on drawn funds can cost about half as much as interest on the full loan amount over the same build.
- **One-close buys certainty:** It sets mortgage terms at the start, while two-close keeps flexibility but repeats the closing.
- **Programs differ on down payment:** FHA starts at 3.5% with a 580 score, while VA and USDA can allow no down payment for those who qualify.
- **Iowa protects each payment:** Check the lien registry and collect lien waivers before every draw.

Keep your builder's final paperwork moving so conversion is not delayed."}}]}]
