If you own a home and want to move up, the question I hear most is some version of "how do I buy and sell a house at the same time without paying two mortgages or living out of boxes for months?" The honest answer is that almost nobody pulls this off by luck. People who do it smoothly pick one of four approaches before they list: sell first and then buy, buy with a home sale contingency, buy first using the equity in the current home, or line up both closings on the same day.
Which one fits you comes down to two things: whether your income can carry both housing payments for a while, and how much equity you have in the home you are leaving. A good pre-approval conversation sorts that out before you ever talk to a listing agent, and that is where I would start.
Start with the lender, not the listing
When you buy before your current home is sold, the lender has to count both housing payments against your income. That is the whole reason this feels hard. The debt to income ratio on the new loan includes your current mortgage, taxes and insurance, plus the new payment, unless your current home has already closed or your file meets specific conditions that let the old payment be left out. The most common exception is a signed purchase agreement on your current home with the buyer's financing and inspection contingencies already cleared. The rules depend on the loan program, so I would rather walk through your actual numbers than have you guess.
Ask your loan officer to run the pre-approval two ways: as if your current home is sold, and as if it is not. That tells you right away whether buying first is even on the table. If it has been a while, here is how pre-approval works in Michigan right now. For a move-up purchase, bring a few extra things:
- Your current mortgage statement, and any home equity line statement
- A listing agent's opinion of what your home will sell for, plus a rough net sheet
- Recent pay stubs, two years of W-2s or tax returns, and two months of bank statements
- A note on how much of the sale proceeds you plan to put toward the next home
The four ways to buy and sell at the same time
Sell first, then buy
This is the cleanest path from a lending standpoint. Your old payment is gone, the proceeds are in your account, and your offer on the next home carries no sale contingency, which sellers like.
The downside is where you live in between. The tool most people use is a post-closing occupancy agreement, sometimes called a rent-back, where you stay in your sold home for a short, agreed period after closing. Michigan purchase agreements commonly have an occupancy section, so decide the length you want before you list and have your agent write it in. The buyer's lender will usually want that period kept short, since the buyer is supposed to be moving into a primary residence. If a rent-back is not available, a short-term rental or a few weeks with family is often less painful than people expect.
Buy with a home sale contingency
Here your offer on the new home depends on your current home closing. If your sale falls apart, you can walk away with your earnest money, and you are never stuck qualifying for two payments you cannot carry.
The trade-off is how the seller sees it. When a home has several offers, a contingent offer is usually at the bottom of the pile. When a home has been sitting, sellers are far more open to it, often with a kick-out clause: they keep marketing the home, and if another offer comes in you get a set number of hours to remove your contingency or step aside. Your contingent offer is much stronger if your current home is already listed, and stronger still if it is under contract with the buyer's contingencies cleared.
Buy first using your equity
If your income can carry both payments for a few months and you have meaningful equity, you can buy first and sell afterward. The down payment on the new home comes from borrowing against the one you are leaving:
- A home equity line of credit, opened before you list. Many lenders will not open a new line on a home that is already on the market, so the order matters.
- A bridge loan, a short-term loan secured by your current home that is paid off when it sells. Fewer lenders offer these and the terms vary, so ask early.
- A cash-out refinance of the current home. This is slower and rarely makes sense when you are about to sell, but it comes up when someone plans to keep the home as a rental.
Whichever tool you use, the payment on that borrowed money counts in your debt to income ratio alongside both mortgages, and you carry two sets of taxes, insurance and utilities until the old home closes. I tell people this makes the most sense when their income is steady, their current home is in good shape, and they are willing to price it to sell rather than to test the market.
Close both on the same day
This is more common in West Michigan than you might think. You sell in the morning, buy in the afternoon, and the title company wires the proceeds from the first closing into the second. Your sale has to actually fund, not just sign, before the purchase can close, so both lenders and both title companies need to know the plan weeks in advance. Use the same title company for both sides if you can, and avoid the last business day of the month and late Friday afternoons, because a delayed wire can mean waiting out a weekend with a moving truck in the driveway.
The risk is that a delay on either side pushes both. A low appraisal, a late buyer condition, or a missing payoff letter can all do it. Protect yourself with a cushion of a few days between your sale's contingency deadlines and the actual closing date, and keep a couple of nights of backup housing in mind.
A timeline that works
- Three to four months out: get pre-approved for the move-up purchase, run both ways. Pull your current mortgage statement and ask a listing agent for a net sheet so you know what equity you actually have after the payoff, commissions and Michigan transfer tax.
- Pick your approach. If you are buying first on equity, open the home equity line now, before the sign goes in the yard.
- Prep and price the current home. Handle the repairs a buyer's inspector will flag, and price it to sell on a normal timeline. Every extra week on the market is a week of carrying costs.
- List, then shop in earnest. Start looking seriously once showings begin, and make your strongest offers once you are under contract.
- Accept an offer and set the dates. Ask for the occupancy terms you need, and set the sale closing a few days ahead of the purchase closing if you are not doing same-day.
- Lock the rate on the new home once you are under contract, with a lock period that covers both closings plus a cushion. Rates have moved around this fall; here is where things stood after the latest Fed meeting, and your loan officer can tell you how the lock lines up with your dates.
- Final walkthroughs and closing. Walk through the home you are buying, hand over keys on the one you are selling, and move.
Two mistakes I would avoid anywhere in this window: opening new credit for furniture, appliances or a vehicle, because it shows up on the final credit check and can change your approval, and keeping either agent in the dark about your plan and your dates.
What to do this week
- Pull your most recent mortgage statement and write down the payoff balance.
- Ask a local listing agent for an opinion of value and a net sheet, and build in room for a lower offer or a repair credit.
- Get pre-approved for the move-up purchase, run both with and without your current payment. You can reach me here to start that conversation.
- Decide which of the four approaches you are leaning toward and tell your agent, so the listing and the offers are written to match.
- Look at your savings and decide how many months of two payments you could carry if the sale takes longer than planned. That answer tells you a lot about which path is right.
Buying and selling at the same time is a logistics problem more than a money problem once you know your numbers. Get those first, pick a lane, and the rest is scheduling.
