Start with the monthly payment you are comfortable with, including principal, interest, property taxes, insurance and any HOA. Lenders often look at your total debts compared with income. Get preapproved by a lender to see what you qualify for, then set your own budget at a payment you can live with, which may be lower.
Begin with the payment, not the price
Your monthly payment includes: - Principal and interest (depends on price, down payment and rate) - Property taxes (vary by county and municipality) - Homeowners insurance - Mortgage insurance if your down payment is small - HOA dues for some homes and condos
Rates today
The 30-year fixed averaged 7.24% and the 15-year 6.60% the week of 10/29/2026 (Freddie Mac PMMS). A small rate change can move your payment noticeably, so ask your lender about rate buydowns and seller credits.
Down payment options
Some loan programs allow low down payments, and there are down payment assistance programs for eligible buyers. A lender can tell you which you qualify for.
Debt to income
Lenders compare your monthly debts, including the new payment, with your gross income. Paying down a car loan or credit card can change what you qualify for.
Get preapproved
A preapproval means a lender has reviewed your income, assets and credit. It tells you what you can borrow and makes your offers stronger. Bring pay stubs, W-2s or tax returns, bank statements and ID.
Set your own comfort number
What you qualify for and what feels comfortable are not always the same. Leave room for savings, repairs and life.

Mistakes first-time buyers make
- Shopping before getting preapproved
- Forgetting taxes, insurance and HOA in the payment
- Opening new credit or changing jobs before closing
- Draining savings for the down payment with nothing left for repairs
Your next steps
- Gather pay stubs, tax returns, bank statements and ID.
- Talk to two lenders and compare Loan Estimates.
- Choose a comfortable monthly payment.
- Start your search with a buyer's agent. See what a buyer's agent does.
A St. Louis payment example
For illustration only: a $250,000 purchase with 5% down, a 7.24% 30-year rate (Freddie Mac, week of 10/29/2026), plus estimated taxes, insurance and mortgage insurance, could put the monthly payment somewhere around $1,950 to $2,150 depending on the property's taxes and your loan. A $340,000 purchase (the St. Louis City and County median, September 2026, St. Louis REALTORS) would be higher. Your lender's Loan Estimate gives your real number.
Ways to lower the payment
- A larger down payment
- A seller credit toward a rate buydown
- Comparing loan types, including adjustable rate mortgages (ARMs were 11.3% of applications in late October 2026, the highest in over a year, MBA)
- Shopping property taxes and HOA dues, which vary a lot by municipality
Property taxes vary by location
St. Louis area property taxes depend on your county, city, school district levies and assessed value. Two homes at the same price can have different tax bills. Ask for the actual tax history on any home you consider.

Programs worth asking about
Ask lenders about down payment assistance for eligible buyers, VA loans for eligible veterans and service members, FHA loans with smaller down payments, and USDA loans for eligible areas outside the urban core. Each has its own rules for income, location and property condition. Comparing two or three lenders helps you see which programs and fees fit you best, and the choice of lender is always yours.
Frequently asked questions
How much income do I need to buy a house in St. Louis?
It depends on price, rate, down payment, taxes and your other debts. A lender preapproval gives you a real number.
What is the difference between prequalified and preapproved?
Prequalification is an estimate; preapproval means a lender reviewed your documents and credit.
Do I need 20% down to buy a home?
No. Many programs allow smaller down payments, though mortgage insurance may apply.
What can a seller credit do for my payment?
A seller credit can pay closing costs or buy down your rate, which may lower your monthly payment. Ask your lender.
