How to Buy Before You Sell: Options That Really Work

The question that stalls more moves than any other is simple: how do I buy the new place before the old one sells? You have more options than waiting for a buyer, selling first, and moving twice. Buyers across Bradenton, Lakewood Ranch, and the Gulf Coast routinely bridge that gap with home equity, bridge loans, and rent-backs. Here's how each option actually works, what it tends to cost, and how to pick without overcomplicating the decision.

Start with what you actually have: your equity

Every buy-before-you-sell strategy runs on equity, so this is where the honest numbers begin. Equity is your home's market value minus what you owe on it. According to ATTOM data cited by Florida Realtors, roughly 6 in 10 mortgaged homes in Florida were equity-rich at the end of 2024, meaning combined loans were at or below half of the property's value. The flip side matters too: a CoreLogic measure showed Florida's average homeowner equity declined by about $18,100 through 2024, with Sarasota among the metro areas where the slip was concentrated. National averages, in other words, do not set your number. Your equity is set by your home, your market, and last quarter's sales, which is exactly why the estimate comes first.

Option one: a HELOC against your current home

A home equity line of credit turns your equity into a revolving line you can draw on for the new down payment, then repay when the old house sells. Lenders typically want you to keep roughly 15 to 20 percent equity after the draw, which usually means a combined loan-to-value cap near 85 percent. Rates are the main attraction: the average HELOC rate sat around 7.5 percent in September 2026 according to Experian, well below what most bridge loans cost. A 10-year draw period with interest-only payments is common. The catch is qualification: you need the income to carry the old mortgage and the line at the same time, at least until closing day on the new home.

Option two: a bridge loan for the gap

A bridge loan is short-term money designed exactly for this problem. It runs 6 to 12 months, typically interest-only, and gets paid off with your sale proceeds at closing. Many lenders let you borrow up to roughly 80 to 85 percent of the current home's value, so it can cover a larger purchase gap than a HELOC alone. It is also the priciest route: rates commonly land around 9 to 11 percent, with origination fees near 1 to 2.5 percent of the loan. Use it when the timing is real, the sale is imminent, and you want maximum buying power in the meantime.

Option three: sell first, then rent your own house back

A rent-back turns the problem the other direction: you sell first, close, then rent the property back from the buyer for a set window, commonly 30 to 90 days, while you close on the new home and move once instead of twice. Two practical notes: many lenders cap the rent-back at about 60 days to satisfy owner-occupancy rules, and the rent is usually set at the buyer's daily carrying cost plus a security deposit. It does not give you six months of runway, but it removes the stress of a double move and a gap with no place to land.

Option four: the home-sale contingency, and its honest warning

You can make your offer contingent on selling your current home first. It is the most comfortable option for you and the least attractive to sellers, so in a market with multiple offers it is often the first one set aside. If you go this route, have the current home priced and show-ready before you write the offer, so the contingency reads as a short timeline and not an open-ended one.

Which option fits your situation?

The right answer comes from four questions: how much equity you really have, how fast you need to move, whether you can comfortably carry two payments for a few months, and how competitive the buyer market is right now. A HELOC fits a flexible timeline with strong income. A bridge loan fits a fast, certain sale. A rent-back fits a buyer who wants one clean move. None of them beats a realistic equity number, which is where any move should start. Still deciding whether selling is right at all? I covered the options to weigh before you list in a separate post.
