How much house can I afford?

Mortgage affordability calculator

Work backward from your income, monthly debts, and down payment to the price a lender will likely support — then see the full monthly payment behind it, taxes and insurance included.

Approval amount and comfortable amount are two different numbers

A lender approves you on debt-to-income ratio: your total monthly obligations, including the new housing payment, divided by your gross monthly income. Most conventional programs stretch to roughly 43-50% DTI, and that ceiling is often well above what actually feels comfortable once you are living in the house.

This calculator shows both sides. Enter your income, existing debts, down payment, and a target DTI, and it returns the price that supports — along with the maximum monthly payment, the supported loan amount, and a full principal, interest, taxes, insurance, and PMI breakdown so nothing surprises you at closing.

Price you can afford

Backed into from your DTI target, not a rule of thumb. Change the DTI and watch the price move so you can find your own comfort line.

Full PITI payment

Principal, interest, taxes, insurance, and PMI where it applies. The payment that actually leaves your account each month, not just principal and interest.

Down payment impact

See how another $5,000 down changes both the price you can reach and whether PMI applies at all.

What it looks like as a house hack

One click into the house hack tab and you can see how renting part of the property changes both the payment and, often, what you qualify for.

Four inputs and you have your number

1

Enter your gross monthly income

Before taxes, and include documented, stable income only — base pay, plus bonus or commission if you have a two-year history of it.

2

Add your monthly debts

Car payments, student loans, minimum credit card payments, personal loans. Do not include utilities, groceries, or your current rent.

3

Set your down payment and rate

Use a real current rate, not the promotional number in an ad. Under 20% down, PMI is added automatically.

4

Adjust your DTI target

43% is a common conventional ceiling. Slide it down to 36% or 30% to see what a genuinely comfortable payment buys — that gap is where most buyer regret lives.

A buyer earning $7,000 a month with $450 in debts

Gross monthly income$7,000
Monthly debts$450
Down payment$20,000
Rate6.8%
Target DTI43%
Maximum monthly payment (PITI)~$2,560
Estimated price supported~$310,000
Same buyer at a 36% DTI~$250,000
Illustrative only. The gap between those last two lines is the real point: the same buyer is approvable at $310,000 and comfortable at $250,000. Neither number is wrong — but you should choose which one you are shopping at deliberately, before you fall for a house at the top of the range. Iowa property taxes vary meaningfully by city and school district, so confirm the tax line for the specific address.

Affordability questions Iowa buyers ask

How much house can I afford on my income?

As a starting point, most lenders will support a total debt-to-income ratio in the 43-50% range, including the new housing payment. On $7,000 a month of gross income with $450 of existing debts, that is roughly a $2,500 to $2,900 monthly payment. Whether that is comfortable depends on your savings rate, job stability, and what else you want your money to do — run the calculator at a lower DTI to see that version.

What is included in the monthly payment?

Principal and interest on the loan, property taxes, homeowner's insurance, PMI if you put less than 20% down, and HOA dues where they apply. Lenders refer to the first four as PITI, and it is the number your escrow account is built around.

Do I need 20% down to buy in Iowa?

No. FHA allows 3.5% down, conventional programs start around 3-5% for qualified buyers, and USDA offers zero-down financing in many of the smaller communities around the Ankeny-to-Ames corridor. Under 20% down you will carry PMI, which typically falls off as you approach 20% equity.

How does a house hack change what I can afford?

Substantially, in two directions. Lenders will often count a portion of the rent from the other units toward your qualifying income, raising the price you are approved for, and the rent then covers part of the payment you actually make. Open the house hack tab in the calculator to model it.

Should I get pre-approved before I start looking?

Yes, and early. A pre-approval turns an estimate into a real number based on your actual credit and documented income, and in a competitive situation your offer is not taken seriously without one. It costs nothing and does not obligate you to that lender.

What do closing costs run in Iowa?

Buyer closing costs commonly land in the 2-3% range of the purchase price, covering lender fees, title work, appraisal, and prepaid taxes and insurance. On a $300,000 purchase that is roughly $6,000 to $9,000 on top of your down payment — budget for it separately.

Estimates are for educational use only. This is not financial, lending, tax, or investment advice, and it is not an appraisal. Rates, taxes, insurance, and PMI are estimates — confirm your actual numbers with your lender and tax professional.
