What does a move-up purchase look like in the first 30 days in West St. Louis County?

What does a move-up purchase look like in the first 30 days? Week one is your numbers and your lender, week two is choosing the order of your sale and purchase, week three is getting your current home ready, and week four is shopping and writing offers with a plan already in place.

Over the past week I have heard from several move-up buyers in West St. Louis County, and they all asked me some version of the same question: where do I even start?

I understand why it feels heavy. You are not just buying a home. You are selling one at the same time, and every decision seems to depend on another one. The good news is that there is an order that works. Here is the 30-day timeline I walk my move-up clients through in Chesterfield, Kirkwood, Wildwood and the surrounding St. Louis Metro Area.

Why the order matters right now

In September 2026, 44 homes with three or more bedrooms sold in Chesterfield (63017). The median home sold at 100.0% of list price after a median of 11.5 days on market, and about 6 in 10 sold at or above asking. In Kirkwood, 39 sold at a median of 100.2% of list price after a median of 7 days, and 62% sold at or above asking. (Source: MARIS MLS, September 2026, single-family homes with three or more bedrooms, excluding the lowest price tier. Medians are calculated from closed sales.)

When well-priced homes sell that quickly, how you structure your purchase matters almost as much as what you offer. A clean offer is easier for a seller to say yes to than one that depends on something else happening first.

Week 1: Get your numbers and talk to a lender

Before you look at a single home, you need two answers.

• What could your current home net you? Not the list price. What you would walk away with after the mortgage payoff, closing costs and any repairs. I put together a net sheet for my clients so this is a real number, not a guess.
• What can you comfortably carry? Ask your lender how much you can borrow if you still own your current home, and what options exist for buying before your sale closes. This is a lender question, and the answer is different for every household.

Also write down your must-haves and your nice-to-haves. It sounds simple, and it saves a lot of showings later.

Week 2: Choose your order

Most move-up buyers end up on one of these paths. None is right for everyone.

• Sell first, then buy. You list your home, accept an offer, then shop with a clear budget and a stronger position. The tradeoff is that you may need a short gap before you move. Many sellers ask for time to stay in the home after closing, and I help you negotiate that.
• Buy first with an offer that depends on your sale. You make an offer that is contingent on selling your current home. It protects you from owning two homes, but it can look weaker to a seller when the market is moving fast.
• Overlap the closings. You line up both closings on the same day or close together, with the right financing and timing. This takes coordination, and it is a conversation to have with your lender and title company early.

Here is the question I ask clients to decide: can you comfortably carry two housing payments for a few months if the timing does not line up? If yes, buying first gives you more control. If not, selling first, with a plan for the gap, is usually the calmer path.

Week 3: Get your current home ready before you shop

If you will be selling, this week is where you get ahead. Clear out what you do not need, take care of the small repairs, and plan the preparation before photos are taken. I always tell clients that video is non-negotiable, because a home that looks great in person but poor online loses buyers before the first showing.

Agree on your target listing date now, even if it moves later. Having a date gives every other decision something to line up with.

Week 4: Shop with a plan and write strong offers

By now you have your lender conversation done, your path chosen and your home on a schedule. That is the moment to start touring in earnest. Have your pre-approval ready, know the offer terms you can offer, and decide in advance what matters most to you if you have to choose between price, timing and flexibility.

Strong offers are not always the highest ones. In a fast market, a clear timeline and a seller-friendly closing date can matter as much as the number.

What this timeline does not promise

Every move is different. Your timeline may be shorter or longer, and your lender, title company and tax advisor will have the last word on financing, closing and the tax side. I am a Realtor, not a lender or accountant, and I am glad to work alongside the professionals you already trust. What I can do is make sure you walk into each step knowing what comes next.

Frequently asked questions

Should I buy my next home before I sell my current one? It depends on your finances, your timeline and how quickly homes sell in your area. Buying first gives you more control but means carrying two homes if timing slips. Selling first is often calmer but may need a short gap or time to stay after closing. I help you compare both paths for your situation.

How long does a move-up purchase usually take? Many move-up buyers can get organized in about 30 days, from the lender conversation to touring with a plan, but the full process depends on when your home sells and when you find the right one. Closing timelines are set by your contracts, lender and title company.

Do I need to get my current home ready before I start touring? I recommend planning for it early. You do not need to finish every project, but knowing your target listing date and what needs attention helps you make better offers on the home you want.
