Working Out Whether an Iowa Rental Carries Its Debt
Program and regulatory figures verified October 7, 2026. Details change; confirm your scenario with us.
There is no interactive calculator on this page, because an honest one needs a rate and we do not publish rates. What we can give you is the arithmetic and what belongs in it.
What the ratio actually is
The income the property produces, divided by the debt service that property carries. Above 1.0 the property covers its own loan payment; below it, it does not.
That is the whole concept, and it is why the product does not need your tax returns: the question is about the property, not about you.
★ Why there is no calculator widget here
Because the denominator is the debt service, and debt service needs a rate. We do not publish rates or payment figures. They depend on the file and on the day.
A calculator that invents a rate produces a number you would then plan around, which is worse than no number. So instead: send us the property and we will run it on the real file with real pricing. One phone call, a real answer.
★★ The gap the yield table does not show
This is the part worth internalising. Every figure in our market table is a gross yield, annual rent over typical value. Nothing has been deducted.
What sits between gross yield and the income a DSCR calculation can actually use:
- Property tax. Usually the largest line, and in Iowa it has state-specific features (below).
- Insurance. Landlord policy, not a homeowner policy.
- Vacancy. Not a hypothetical. On $1,006 of Burlington rent, one vacant month is a meaningfully larger share of annual income than one vacant month on $1,317 in Sioux City.
- Management. If you are out of state, this is a real percentage and not optional.
- Maintenance and capital expenditure. A roof is not an operating expense until the year it is.
- HOA, where applicable.
★ So a property screening at 8.25% gross is not an 8.25% property. The screen tells you where to look; the file tells you what carries.
★ The three Iowa-specific items
No homestead credit. Iowa Code ch. 425 needs an owner "occupying as a home on July 1" and occupying "for at least six months." A rental fails both, so the credit, worth the actual levy on the first $4,850 of actual value, is simply absent from your numbers. An owner-occupant comparison next door is not your comparison.
Classification on 3-plus units. The multiresidential class for parcels with "three or more separate dwelling units" applied only to valuations established 2016 through 2021. What those parcels are classified as now is the county assessor's answer, not ours, and it drives the assessment and therefore the tax line. Why we will not guess.
No rollback or effective rate published here. The assessment limitation is set administratively each year and we did not read the current figure at a primary source. Ask the assessor for it alongside the classification; both come from one phone call. The tax line.
What makes a file answerable
Four things, and with them we can give you a real ratio rather than a range:
- The address.
- The rent: in place with a lease, or market with support.
- The assessor's current assessed value, classification and tax figure.
- Your insurance quote, or let us point you at one.
Everything else we can estimate honestly and tell you we are estimating.
And one thing that does not appear in any ratio
The exit. It does not change the DSCR, but it changes how the loan is priced, and Iowa's is unusually clean: two months post-judgment on a non-owner-occupied property, no post-sale redemption for anyone. The statute.

Frequently asked questions
What is a good DSCR on an Iowa rental?
A ratio above 1.0 means the property's income covers the debt service that property carries. The specific threshold a lender requires is a program term that changes, so we give it against your actual file rather than publishing it. What matters more in practice is using net income rather than gross rent in the numerator.Why does gross rental yield overstate what a property earns?
Because nothing has been deducted from it. Gross yield is annual rent divided by typical value, so property tax, insurance, vacancy, management, maintenance, capital expenditure and any HOA all sit outside it. A property screening at 8.25% gross is not an 8.25% property; the screen shows where to look.Why is there no DSCR payment calculator on this page?
Because the debt service side of the ratio needs an interest rate, and we do not publish rates or payment figures. A calculator that invents a rate produces a number you would plan around, which is worse than no number. Send the property and we will run it on the real file with real pricing.What Iowa-specific costs should go into a DSCR calculation?
Three. A rental gets no homestead credit, which requires owner occupancy on July 1 and for six months, so an owner-occupant's tax comparison is not yours. On a parcel with three or more dwelling units the classification is assigned by the county assessor, since the multiresidential class closed to valuations established on or after 1 January 2022. And the assessment limitation percentage is set administratively each year, so get it from the assessor.Mike Certo · NMLS #260555 · Cornerstone First Mortgage NMLS #173855 · Equal Housing Lender.

Iowa foreclosure procedure, redemption and deficiency rules are set by the Iowa Code and change; figures here carry the date we verified them against the code itself. Gross yield figures are a market indicator built from published typical values and typical asking rents, not a property-level underwrite: they exclude taxes, insurance, vacancy and management. Property classification and assessment are determined by the county assessor. All loans are subject to borrower, property and program qualification.
