You own the house outright, and that one fact gives you the cleanest solution available: open a home equity line of credit on your current home before you list it, and use it as the down payment on the next one. Then buy first, move at your own pace, and sell the empty house afterward. The timing is the whole trick. Lenders generally will not open a HELOC on a home that is already on the market, so this has to happen before you list, not after you get an offer. Most people find that out in the wrong order. The thread already mentioned bridge loans and rent-backs, both valid. Here is how I would rank your options given what you described: 1. HELOC opened pre-listing. Cheapest of the three, you control the timing completely, and with no mortgage on the property you have maximum borrowing room. Pay it off from the sale proceeds when the house sells. 2. Bridge loan. Does the same job, costs more, but requires no advance planning. This is the fallback if you have already listed. 3. Post-closing possession, sometimes called a leaseback or rent-back. You sell, then stay in the house for an agreed number of days after closing while you close on and move into the next one. In Illinois this is normally handled as a rider your attorney adds during attorney review, with a daily rate and money held back in escrow. Ask for 30 days, not 5. You already learned what one day feels like. 4. Buy before you sell programs. Several companies will buy your next home for cash on your behalf and sell you back to it once your house closes. They work, they are legitimate, and they are the most expensive option on this list. Worth a look only if the first three are closed to you. Two things that will save you regardless of which route you pick: Do not agree to same-day back-to-back closings again. You already know how that ends. Build in at least three business days between them, and make the possession terms explicit in writing rather than a friendly understanding. Illinois gives you attorney review on both contracts. Use the same attorney for the sale and the purchase, and tell them at the start that the possession timing is your top priority. They can coordinate two closings far better than either agent can, because they see both files. One update since 2021: HELOC rates are meaningfully higher now than when you asked, so run the actual carrying cost for the two or three months you would use it. It is still usually cheaper than a bridge loan, but it is no longer nearly free the way it looked back then. I am a real estate professional, not an attorney or a lender.
