The First-Time Home Buyer's Guide to Buying in St. Louis

Buying your first home is one of the biggest financial decisions you'll ever make, and most people walk into it knowing only pieces of the picture. That's not your fault; nobody sits you down and explains how it actually works. This guide does that, start to finish, for the St. Louis area specifically, including the local details that generic national guides leave out.

The goal here isn't to push you toward buying. It's to help you understand the process clearly so that when you're ready, you can move with confidence instead of confusion.

A quick note on geography: in this guide, "St. Louis" means the whole metro on both sides of the river, the Missouri side and the Illinois Metro East. Where something works differently depending on your state, I'll call it out.

How does buying a first home in St. Louis actually work?

The process has a clear order. Here's the whole arc:

1. Hire a buyer's agent. Your first move is choosing an agent to represent you (not the seller). You'll sign a buyer's agency agreement (more on that in the paperwork section), and from there your agent guides every step below.
2. Get pre-approved. Talk to a lender and get a pre-approval letter, so you know what you can actually borrow and can show sellers you're serious. If you don't already have a lender, a good agent can connect you with trusted, vetted lender partners to compare. (Paying cash? You'll show proof of funds instead.)
3. Figure out your real budget. Your price range isn't just the loan; it's the monthly payment including taxes and insurance, plus the cash you'll need up front.
4. Search for homes. Your agent sends you listings matching your criteria and you tour what fits.
5. Make an offer. Your agent prepares the offer, you review every line together, and you negotiate price and terms.
6. Inspections. Once your offer is accepted, you typically have an inspection period (often up to 10 days, depending on your contract) to check the home's condition and walk away or renegotiate if something serious turns up.
7. Title and the loan move in parallel. The title company runs a title search and prepares closing; your lender finalizes the loan.
8. Secure homeowners insurance. You'll need a policy in place before closing.
9. Close. You sign a stack of documents, your funds transfer, and you get the keys.

It usually takes about 30-45 days from accepted offer to closing, though it varies.

How much money do you really need up front?

This is where first-time buyers get surprised, so let's be specific. You need cash for three things:

• Your down payment. This can be far less than the "20%" everyone repeats. Many first-time-buyer loans allow 3-3.5% down, and assistance programs (below) can lower it further.
• Closing costs. In Missouri, buyer closing costs typically run 2-5% of the purchase price. On a $275,000 home, that's roughly $5,500-$13,750. On the Illinois (Metro East) side, plan for 3-5%; Illinois handles a few closing costs differently from Missouri (see the Metro East note below).
• Inspection money. You pay for inspections out of pocket during your inspection period, usually a few hundred dollars total (see below).

One Missouri advantage: Missouri does not charge a statewide real estate transfer tax, which keeps closing costs lower than in many states. Illinois does charge one, about 0.15% of the price, but there it's customarily the seller's cost, not the buyer's. And if you're buying on the Metro East side, a couple of Illinois differences can actually work in your favor (see below).

Down payment assistance (Missouri and Illinois)

You may not have to cover the down payment entirely on your own:

• Missouri, MHDC First Place: the Missouri Housing Development Commission offers first-time buyers up to 4% of the loan amount toward down payment and closing costs, as a second loan that's forgiven if you stay in the home for 10 years.
• Illinois, IHDAccess Home: launched March 2026, this offers up to $15,000 (6% of the purchase price) in down payment and closing-cost help as a zero-interest second mortgage, deferred up to 30 years.

One thing to confirm before you count on it: some IHDA and local municipality grants require a prorated repayment if you sell the home before the end of the grant term (often 5, 7, or 10 years). Both programs also have income and purchase-price limits and other conditions. Ask a participating lender whether you qualify and how the repayment terms work; that's the right person to confirm your specific numbers.

Buying on the Illinois (Metro East) side? A few real differences

Missouri and Illinois handle a few things differently at the closing table. If you're buying across the river, these are worth knowing.

• The transfer tax is the seller's cost, not yours. Illinois charges a real estate transfer tax of about 0.15% of the price ($0.50 per $500 to the state plus $0.25 per $500 to the county), and by custom the seller pays it (Illinois REALTORS). On a $250,000 home that's roughly $375. A small number of Illinois municipalities (mostly in the Chicago area) add a local transfer tax on top, but that's not something you'll typically run into on the Metro East side. As the buyer, your recording fee is small: a flat county charge, usually around $110-140.
• Property taxes can work in your favor at closing (the big one). Illinois property taxes are paid in arrears, always about a year behind (Illinois Dept. of Revenue). Because the seller has been living in the home building up taxes that haven't been billed yet, at closing they credit you for their share. That credit can be large enough that you bring little or no cash to closing, and occasionally you even leave with money back. Your closing attorney or title company calculates the exact amount.
• Disabled-veteran property tax relief. Illinois offers a Standard Homestead Exemption for Veterans with Disabilities, tiered by service-connected disability rating: $2,500 off assessed value at 30-49%, $5,000 at 50-69%, and a full exemption on the first $250,000 of value at 70% or more, subject to eligibility (Illinois Dept. of Revenue). For a qualifying veteran, that can mean dramatically lower, or zero, annual property tax.

What inspections matter in St. Louis?

Inspections are your protection. This is the St. Louis-specific part most guides miss, and it's where local knowledge actually saves you money.

• General home inspection (~$350-$550): overall condition, roof, structure, appliances, electrical, HVAC.
• Mechanical / gas inspection (~$200): checks the HVAC system and gas appliances, and pressure-tests the fuel lines so there are no gas leaks.
• Sewer lateral (~$150-$200 to scope): older STL pipes fail; cleaning runs ~$350+ and repairs can reach the thousands. Many cities have repair programs.
• Radon (~$150): about 1 in 5 Missouri homes test high (closer to 1 in 3 in St. Louis County); EPA action level 4.0 pCi/L.
• Termite (~$100): standard in this region; often required by lenders.

Cost ranges as of mid-2026; actual prices vary. Deemed reliable but not guaranteed.

A few things worth knowing:

• Radon is a real Missouri issue. Roughly 1 in 5 Missouri homes have elevated radon, and in St. Louis County it's closer to 1 in 3 (MO DHSS). The EPA recommends acting at 4.0 pCi/L, and mitigation typically runs around $700. The Missouri Department of Health and Senior Services even offers free radon test kits, so testing during your inspection period is cheap insurance.
• Sewer laterals are a real St. Louis issue. The line connecting your home to the public sewer is the homeowner's responsibility, and with much of St. Louis's infrastructure being older, it's not uncommon to find problems during a scope. Even newer homes can have issues from construction debris. A general cleaning runs around $350+, and actual repairs can climb into the thousands. Because the costs can be steep, many St. Louis-area municipalities run sewer lateral repair programs to help, though coverage and approval rules vary. Worth checking for any home you're serious about.

Don't forget the occupancy inspection and permit

Here's one almost no national guide mentions: many St. Louis-area cities require an occupancy inspection (a basic safety/code check) before you can move in and get your occupancy permit. It's separate from your private home inspection, and rules vary by municipality: not every city requires one, and some areas require more than one.

How it works locally matters, because it's easy to get wrong. Under the most common area sales contract, the seller typically orders the inspection and has to tell you, within about 15 days, of anything they won't fix to make it pass. If the seller flags something in that window that they won't fix for occupancy, that becomes a point of negotiation between you and the seller. If they don't flag anything, the seller is required to make it pass for you. In some municipalities, you (the buyer) then pull the actual occupancy permit; some contracts put the whole thing on the buyer. Either way, this is a moving part your agent should be actively managing so nothing slips, and because wait times can run weeks in some cities, it gets started early. Fees are modest (for example, around $120 in the City of St. Louis).

What paperwork will you actually see?

You'll sign a lot, and it helps to know what shows up when. Here's the paperwork you'll actually handle, roughly in order:

• Buyer's agency agreement: usually the first thing you sign. Since 2024, buyers sign a written agreement with their agent before touring homes. It spells out how your agent represents you and how they're paid.
• Purchase agreement: the contract between you and the seller, covering price, terms, and timelines. Your earnest money deposit (a good-faith deposit that applies toward your costs at closing) goes down with this.
• Amendments and notices: during the deal, changes and required disclosures happen in writing: an inspection notice requesting repairs, an amendment adjusting a term, and so on. A lot of the real negotiation lives here.
• Inspection reports: the building inspection report and any specialty reports (sewer, radon, termite) you'll review during your inspection period to decide how to proceed.

Then, at closing and after, you'll encounter documents you don't handle earlier: the deed of trust (Missouri uses a deed of trust rather than a traditional mortgage instrument), your title insurance policy (protection against hidden problems in the property's ownership history), and eventually the recorded deed, which is mailed to you weeks after closing.

A few terms that come up constantly: PITI (principal, interest, taxes, insurance, the four parts of your monthly payment), appraisal (a lender-ordered opinion of the home's value), and comps (comparable recent sales used to price an offer).

What does a good buyer's agent actually do for you?

In St. Louis, a buyer's agent guides the whole process: pulling listings that match your criteria, preparing and negotiating your offers, coordinating with the title company and lender to keep your closing on schedule, managing inspection and contract deadlines so nothing slips, walking the home with you before closing, and getting you to the finish line with the documents signed and the keys in hand.

The real value isn't opening doors; it's catching the things you wouldn't know to look for, and making sure deadlines and protections in your contract actually get honored.

Common first-time-buyer mistakes in St. Louis

• Skipping pre-approval and shopping blind. You waste time on homes you can't finance, or lose one you can because you weren't ready to offer.
• Underbudgeting for cash. Down payment is only part of it; closing costs and inspections are real money.
• Waiving inspections to win a bid. In a competitive moment it's tempting, but for a first home it's a big risk. There are safer ways to strengthen an offer.
• Making big financial moves before closing. Changing jobs, financing a car, or opening new credit cards between pre-approval and closing can sink your loan. Keep your finances stable until the keys are in your hand.
• Forgetting the occupancy inspection timeline. With multi-week waits in some cities, this needs to be ordered early.
