Freddie Mac PMMS announced this week that the average rate for a 30-year fixed mortgage is around 6.6%. Specifically, it ranges from 6.55% to 6.72%. This is as of July 2026. For those searching for their first home in St. Louis, this number can significantly impact the monthly payment they will need to make.

According to Redfin, the median home price in St. Louis over the past three months is $255,000, which is a 6.2% increase from the previous year. The average home value across the city is slightly different, at $177,270 according to Zillow, which reflects only a 0.5% increase from last year. The difference in these figures is due to the methods of calculation, whether looking at only homes sold or considering the entire inventory.

Let's start by outlining the types of loans available. An FHA loan can start with a down payment of 3.5% if your credit score is 580 or higher. If your score is between 500 and 579, a 10% down payment is required. A conventional loan may be available starting at 3% for first-time homebuyers or those with a household income at or below 80% of the area median income. However, if you put down less than 20%, you will incur PMI, or private mortgage insurance, which is an additional monthly cost. Putting down 20% or more eliminates this cost.

When choosing a mortgage product, in addition to the 30-year fixed rate, adjustable-rate mortgage (ARM) products that adjust after a certain period may also catch your eye. While the initial rate may seem low, the payment can change after the adjustment, making fixed-rate mortgages easier for first-time homebuyers to plan for.

Your credit score and DTI, or debt-to-income ratio, will determine both your approval and interest rate terms. Getting pre-approved by a lender can enhance your negotiating power when making an offer. This way, you won't feel rushed when you find a home you like. Lenders also consider employment stability and whether you have reserves in addition to your credit score and DTI. Having your documents organized in advance can make the pre-approval process smoother.

The effective property tax rate in Missouri is about 0.89% (Tax Foundation, as of 2026). There can be variations by county, so even within St. Louis County, tax rates can differ by area. Be sure to check the tax rate for the specific address before moving. Closing costs typically range from 2% to 5% of the loan amount, which includes appraisal fees, title insurance, and loan origination fees. You will also need to prepare earnest money to show your commitment when making an offer, and remember that there will be additional costs for a home inspection after the contract is signed.

If your down payment is tight, consider looking into the Missouri Housing Development Commission's First Place program. Through the Cash Assistance Loan, you can receive up to 4% of the loan amount as a forgivable second mortgage, and if you live in the home for 10 years, you won't have to pay it back. There are income limits and maximum home price criteria, so check the eligibility requirements through MHDC. In addition to First Place, MHDC also operates the Next Step Program, which offers down payment and closing cost assistance even for those who are not first-time homebuyers.

If you are considering school districts preferred by Korean families, refer to ratings from GreatSchools or Niche, but keep in mind that school district boundaries change frequently, so verify the assigned school for the specific address before purchasing. If you are moving from another state, budgeting based on property taxes or insurance rates from your previous state may lead to discrepancies, so it's advisable to calculate separately.
