Iowa has one of the best zero-down mortgage programs in the country, and most Central Iowa buyers have never heard of it. The USDA Rural Development Guaranteed Loan - Section 502 - offers no down payment, no private mortgage insurance, and a 30-year fixed rate to buyers in eligible areas. Many communities in the Ankeny-to-Ames corridor qualify right now. If you are buying your first home and stretching to get to 3.5% down for FHA, it is worth spending ten minutes checking whether USDA gets you there faster.
Here is what the program actually covers, what it costs, and which Central Iowa communities are currently eligible.
The USDA Rural Development Guaranteed Loan is a government-backed mortgage program administered by the U.S. Department of Agriculture. "Guaranteed" means the USDA insures the loan against default, which lets approved lenders offer it at competitive rates with no down payment requirement.
It is not a subsidy, and it is not limited to farmland or rural counties in the traditional sense. Many established suburbs and smaller cities qualify based on population data - and that eligible-area map is updated periodically as populations shift. A town that qualifies today may not qualify in two years, and vice versa.
Two things it does not do: it does not allow multi-family properties (duplexes, triplexes, or fourplexes) and it is for primary residences only. If you are looking to house hack with a two-unit, USDA is not the path - FHA's multi-family program is. If you are buying a single-family home to live in, keep reading.
Zero down does not mean zero cost. USDA replaces private mortgage insurance with two guarantee fees:
Compare that to FHA, which charges a 1.75% upfront MIP plus 0.55% annually - and the annual portion does not go away until you have 11 years of payments if you put less than 10% down. USDA's annual fee effectively disappears once you hit 20% equity and refinance. For buyers who plan to stay a few years and build equity, USDA frequently wins the total-cost comparison against FHA even at the same rate.
USDA sets income limits at 115% of the area median income (AMI) for the county and household size. For most Central Iowa households in 2026, that works out to approximately $110,000-$125,000 for a household of 1-4 people, with higher limits for larger households.
The income calculation uses all adult household members' income - not just the borrowers. If you have a non-borrowing spouse or a parent living in the home, their income may be counted. This catches some buyers off guard: two earners in a household can cross the limit even when one earner alone would qualify. Your lender will run this calculation as part of the application; it is worth doing informally before you start shopping.
Income above the limit is a hard disqualification. There is no waiver or exception process for USDA loans.
The most direct way to check any property is the USDA's own eligibility map at eligibility.sc.egov.usda.gov - enter the property address and it returns a pass or fail in about ten seconds. That said, here is where Central Iowa currently stands for the communities I work in most often:
Eligibility boundaries do shift. Before you build your search around a specific community's eligibility, verify the specific address on the USDA map - not the city or zip code generally.
Most USDA-approved lenders want a 640 or higher credit score for the automated underwriting path. Scores below that are not an automatic decline, but they typically require manual underwriting - more documentation, more scrutiny, and a longer timeline. If your score is in the 620-639 range, ask your lender specifically about manual underwriting before you assume USDA is off the table.
The property has to be a primary residence, single-family home in an eligible area. It needs to meet USDA's minimum property requirements, which are similar in spirit to FHA's - the home should be safe, sound, and sanitary. A house needing a new roof before move-in may require repairs before the loan closes. Major deferred maintenance is something to look at carefully if you are on USDA.
There is no maximum loan amount set by USDA itself - the limit is whatever the lender will approve based on your income, debt, and the property's appraised value. In practice, most USDA buyers in Central Iowa are purchasing in the $200,000-$350,000 range.
If you are a first-time buyer with limited cash, you are typically looking at three paths:
The short version: USDA can be as low as 0% down. Every figure above moves with your credit, income and the property, so consult a lender before you plan around any of them - and if you do not know where to start, let me know and I will make an introduction.
If you qualify on location and income, USDA almost always wins the cash-to-close comparison. The upfront guarantee fee finances into the loan - you do not need it at the table. Your cash requirement is essentially closing costs only, which can sometimes be negotiated into the seller's concessions.
Iowa also has the IFA FirstHome down payment assistance program, which can be layered with USDA in some cases. If you are looking at a USDA-eligible community and want to explore assistance on top of it, ask your lender specifically whether the two programs can be combined for your scenario.
USDA loans take a few days longer to close than conventional loans because the file has to go through a USDA state-level review after lender underwriting. In Iowa, that review currently runs five to seven business days, though it fluctuates with volume. Budget 45 to 50 days from application to close rather than the 30 to 35 days that conventional buyers target.
In a competitive Central Iowa offer, that timeline matters. If you are writing on a home where multiple buyers are interested, your agent should communicate your timeline clearly in the offer. Some sellers care about a quicker close; others care more about certainty. A well-prepared USDA buyer is not necessarily a weaker offer - the financing is government-backed and the review process is predictable - but it does require the right explanation.
If you think USDA might be your path: the first step is a conversation with a lender who closes USDA loans regularly in Iowa. Not every lender does, and USDA-specific underwriting experience matters. A good lender will run your income against the area limits, check the address map for you, and tell you inside 30 minutes whether you are a strong candidate.
Once you know you qualify, the home search strategy shifts - because the best USDA values in Central Iowa tend to be in the communities most buyers are not looking at. Huxley, Gilbert, Nevada, Slater, and Elkhart each have their own character, school district, and commute profile. I know these markets well.

I will help you understand what the loan mechanics mean for your offer strategy, your timeline, and your bottom-line cost - and I will connect you with a lender who knows USDA in Iowa specifically.

Verify all figures with a USDA-approved lender and the current USDA eligibility map before making borrowing decisions.
