The First-Time Home Buyer’s Guide to St. Louis County, MO
From pre-approval to closing day — a clear, step-by-step roadmap for buying your first home in Kirkwood, Webster Groves, Ballwin, Mehlville, Oakville, Affton, and across St. Louis County.
To buy your first home in St. Louis County, you’ll typically need to: (1) check your credit and budget, (2) get pre-approved with a local lender, (3) explore down-payment help through Missouri’s MHDC programs (and a VA loan if you’re a veteran or active-duty), (4) work with a local agent to find the right home, then (5) make an offer, complete inspection and appraisal, and close. St. Louis County offers an unusually wide range of price points — from more affordable starter homes in Mehlville, Oakville, and Affton to pricier Kirkwood and Webster Groves — so there’s a realistic entry point for most first-time buyers.
Buying your first home is exciting — and a little overwhelming. The good news: St. Louis County gives first-time buyers a lot to work with. There’s real variety here, from walkable older suburbs to newer subdivisions in West County, a deep supply of starter homes and condos in south county, and lower property taxes than just across the river in Illinois.
This guide walks you through the entire process in plain English, with the local details that actually matter — from Missouri down-payment assistance to what to expect at closing.
Why St. Louis County is a great place to buy your first home
Few places in the metro give first-time buyers as many options as St. Louis County. Want walkable and established? Look at Webster Groves, Kirkwood, Maplewood, or Affton. Want the most house for your money? South county — Mehlville, Oakville, Lemay — and parts of north county deliver. Prefer newer construction and top schools? West County (Ballwin, Ellisville, Chesterfield) has it. And Missouri’s property taxes are noticeably more moderate than Illinois’, which keeps your monthly payment friendlier.
The 8 steps to buying your first home
Check your credit and set a realistic budget
Pull your credit (free at AnnualCreditReport.com) and look at your score and anything you can clean up. Most first-time-buyer loan programs want a score around 620 or higher, though FHA loans can go lower. Build a budget that includes the mortgage, property taxes, homeowner’s insurance, and any HOA — a smart rule of thumb is to keep your total housing payment under about 28–30% of your gross monthly income.
Get pre-approved before you start shopping
A pre-approval letter tells you exactly what you can afford and shows sellers you’re a serious, qualified buyer — which matters in St. Louis County’s competitive pockets. Talk to a local lender who knows Missouri’s programs and this market. Pre-approval is more than a quick “pre-qualification”: it’s a real review of your income, debts, and credit, so the number you get is one you can shop with confidence. I’m happy to connect you with lenders I trust locally.
Explore down-payment assistance and first-time programs
This is where a lot of first-time buyers leave money on the table. The Missouri Housing Development Commission (MHDC) offers down-payment and closing-cost assistance built for buyers like you (see the program table below), and depending on your situation, FHA, VA, and USDA loans each open different doors. Many first-time buyers in Missouri get in with far less cash up front than they expected.
Partner with a local agent
A first-time buyer’s agent does far more than unlock doors — they help you read the St. Louis County market block by block, spot overpriced listings, negotiate, and steer you clear of expensive surprises. And in most cases, the buyer’s agent’s commission is paid through the transaction, so expert representation typically costs you nothing out of pocket. Choose someone who works this county every day.
Go house hunting — the smart way
Now the fun part. Focus your search on the municipalities and price points that fit your pre-approval, and pay attention to the things that affect resale and daily life: school district (these change quickly across St. Louis County lines), commute, and the difference in property-tax and municipal fees from one town to the next. Tour enough homes to calibrate your eye, but be ready to move quickly when the right one appears.
Make a competitive offer
Your agent will help you land on a price and terms backed by recent comparable sales, plus contingencies that protect you (inspection, financing, appraisal). In the county’s hotter neighborhoods, the strongest offer isn’t always the highest — earnest money, closing timeline, and clean terms all matter. This is where local negotiation experience pays for itself.
Inspection and appraisal
Once your offer is accepted, a professional home inspection tells you the home’s true condition — and gives you room to renegotiate or request repairs if something serious turns up. Your lender will also order an appraisal to confirm the home is worth what you’re paying. Don’t skip the inspection to win a bid; for a first-time buyer it’s one of the most valuable few hundred dollars you’ll spend.
Close and get your keys
At closing you’ll sign your loan documents, pay your down payment and closing costs (typically 2–5% of the loan, though assistance programs and seller credits can offset these), and the home is officially yours. Budget for the move, set up utilities, and look into Missouri’s property-tax credits and any exemptions you may qualify for.

Common first-time buyer mistakes to avoid
Shopping before getting pre-approved. You can fall in love with a home you can’t finance — or lose it to a buyer who was ready. Maxing out your budget. Leave room for taxes, insurance, repairs, and life. Skipping the inspection. A waived inspection can cost you tens of thousands later. Opening new credit before closing. A new car loan or card mid-process can sink your approval. Going it alone. The listing agent works for the seller — have your own representation.
First-time home buyer FAQ — St. Louis County, MO
How much do I need for a down payment in St. Louis County?
Less than most people think. With FHA you can put down as little as 3.5%, conventional loans can start at 3%, and VA and USDA loans can require $0 down. On top of that, Missouri’s MHDC programs can help cover down payment and closing costs, so many first-time buyers get in with very little out of pocket.
What credit score do I need to buy my first home?
Most loan programs look for a score around 620 or higher, but FHA loans can be available with lower scores. A higher score generally means a better interest rate, so it’s worth checking your credit early and cleaning up what you can before you apply.
Are there first-time home buyer programs in Missouri?
Yes. The Missouri Housing Development Commission (MHDC) runs the First Place Loan and Next Step programs, which pair a mortgage with down-payment and closing-cost assistance for first-time (and some repeat) buyers, subject to income and purchase-price limits. They can be combined with FHA, VA, USDA, or conventional loans — a local lender can tell you which current program fits your situation.
How long does it take to buy a home?
From accepted offer to closing usually runs about 30–45 days, depending on your loan. The shopping phase varies — some buyers find the right home in a couple of weeks, others take a few months. Getting pre-approved first keeps the whole process moving when you’re ready.
Do I have to pay my buyer’s agent?
In most transactions, buyer’s agent compensation is handled through the deal, so working with an experienced local agent typically costs you nothing out of pocket — while giving you a professional negotiating and protecting your interests. We’ll always go over exactly how it works for your specific purchase before you commit to anything.
