Selling and buying at once.
Two contracts,
one move.
Most sellers are also buying, and the question is how to get from one house to the other. The cleanest path is to move straight from one to the other: the sale and the purchase close back to back, the sale's proceeds fund the purchase, and you move once without carrying two payments. When the dates will not line up, the fallbacks are a rent-back, a longer close, buying first, or an offer that depends on your sale, and each one has a catch I show you in dollars before you choose.
Which comes first?
If you are buying next, we plan the sale and the purchase together, before your home goes on the market. The goal is to move straight from one house to the other. These are the paths I lay out at the listing consultation, and the catch in each one.
Before you choose, I show you both sides in dollars: what buying first would cost you in carrying two homes, against what selling first costs you in time. If you are buying in the Valley, I represent you on the purchase too, under a separate buyer agreement.
- Close back to back.Your sale closes first and its proceeds fund your purchase the same day or the next, so you move once. The catch: the two contracts depend on each other, so a delay on one delays the other.
- Sell first, rent back.You close the sale, then stay in the house for an agreed period while you finish buying. The catch: you live in a house you no longer own, under a separate written agreement with your buyer.
- Sell first, long close.You agree to a longer closing date to give yourself time to buy. The catch: fewer buyers will wait that long.
- Buy first.You buy, move, then sell the old home. The catch: you carry two payments, and your down payment is often locked in the home you have not sold.
- Buy contingent on selling.Your offer depends on selling your home. The catch: many sellers will not take it, or will only take it with a short deadline.
Move straight from one to the other.
The cleanest way to sell and buy is to close both on the same day or a day apart, with the sale's proceeds funding the purchase. You move once, you never carry two payments, and you never live in a house you do not own. It takes planning, because it stacks two deals, two lenders and two sets of dates on one move. If the sale slips, the purchase slips with it, and your earnest money on the purchase is at risk if you cannot close by the date you agreed. This is how I keep the two lined up.
- Match the dates.I set the sale's close of escrow ahead of the purchase, and line up the inspection, appraisal and loan deadlines on both contracts so they do not collide.
- Keep escrow talking.Both escrow officers need to know the purchase depends on the sale's proceeds, and when each deed is expected to record.
- Plan possession.Your buyer gets the keys when your sale records, unless you have a rent-back. Movers, storage and a place to sleep for a night or two belong in the plan.
- Guard the wire.Before you send or receive closing funds, confirm the instructions by calling escrow at a number you already trust. The Arizona Department of Real Estate warns that wired funds sent to a fraudster are usually not recoverable.
Sell first, rent back.
Under the Arizona REALTORS purchase contract, the buyer is entitled to possession at close of escrow, which is the day the deed records. A rent-back changes that by a separate written agreement, a post-possession agreement, where you stay in the house as the buyer's occupant for an agreed number of days after closing.
A rent-back is the fallback when your purchase cannot close the same day as your sale. You sell with money in hand, you shop with a real number, and you still move only once. If we plan on one, I write it into the listing from day one so every buyer sees it, and we agree the terms up front: daily rent, deposit, utilities, insurance and move-out condition.
It is not risk free. Arizona REALTORS states plainly that post-possession agreements are not recommended and carry inherent risks, that they may be governed by Arizona's Residential Landlord and Tenant Act, and that both sides should get advice from legal and insurance professionals first. You are living in a house you no longer own, so read the terms with that in mind, and weigh them against the other paths.
The terms we agree up front.
Arizona REALTORS publishes sample Post Possession Agreement Provisions for information. These are the points it covers, and the ones I negotiate for you before we accept an offer.
- The fee.A daily amount you pay the buyer for each day you stay. It is not applied to the purchase price.
- The deposit.The buyer may hold a security deposit against damage or a late move-out.
- Utilities.They stay in your name and you pay them until you hand over the keys.
- Insurance.You carry coverage for your belongings and your liability; the buyer carries the hazard policy on the house. Call both carriers before you sign.
- Condition.You keep the house up and hand it back in substantially the same condition as at closing.
- Holdover.A per-day charge if you stay past the agreed date, and the buyer's legal remedies if you do not leave.
The Buyer Contingency Addendum.
If you need the money from your sale to buy, your purchase offer can depend on that sale. In Arizona that is written on the Arizona REALTORS Buyer Contingency Addendum, revised July 2023. It works one of two ways: your purchase depends on you accepting an offer on your current home, or on the closing of your current home that is already under contract.
How it works
The seller you are buying from can keep marketing the home, and the addendum sets out what happens if that seller accepts a back-up offer and the deadlines you then have. You can waive the contingency by showing you can close without the sale: written documentation from your lender that you can close by the agreed date, or evidence of funds on a cash purchase. Since July 2023, if your home is already under contract, the form gives you three days after its scheduled closing to waive. If you do not waive in time, the contract can cancel on the terms the addendum sets, including what happens to your earnest money. We read that section together before you sign.
How sellers read it
When I represent a seller, a buyer who must sell a home first is a weaker offer. That sale is a second deal the seller does not control. Many sellers will not take it, or will only take it with a short deadline. Expect to give something back on price or terms.
When it can work
It reads better when your home is already under contract and the question is only whether it closes, than when your home is not yet listed. It also has a better chance where supply favors buyers. I will tell you plainly whether the house you want is one where it can work.
Bridge loans and HELOCs.
Buying first means you carry two homes until the old one sells: two payments, two sets of taxes, insurance and utilities, and a down payment that is often tied up in the home you have not sold. Two kinds of financing can cover the gap. Whether you qualify, and what it costs, is a question for your lender. I do not recommend lenders or quote rates.
Before you borrow against either home, ask your lender to show you the total cost of carrying both for three, six and nine months. I set that next to what selling first would cost you in time.
A bridge loan
Federal lending rules describe a bridge loan as a temporary loan with a term of 12 months or less, such as a loan to buy a new home when you plan to sell your current one within 12 months. Your lender sets how and when it is repaid.
A HELOC
The Consumer Financial Protection Bureau describes a home equity line of credit as an open-end line that lets you borrow against your equity. Most carry a variable rate, so the payment can change, and if you cannot repay you could lose your home.
The test
If the old home takes longer to sell than you planned, can you carry both payments without strain? If the honest answer is no, sell first.
Temporary housing.
If the dates do not meet, you need somewhere to be between the two keys. The common answers are a rent-back on the house you sold, a short furnished rental, or staying with friends or relatives, with your things in storage. Price each one before you choose a path: a month of rent and two moves can still cost less than carrying two mortgages, and sometimes it does not. I lay the numbers side by side.
Start with what your sale nets. The seller net calculator gives you a working number, and I true it up with a real value for your home.
Common questions
Should I sell my house first or buy first in Arizona?
Move straight from one to the other when you can: your sale closes first and its proceeds fund your purchase the same day or the next, so you move once and never carry two payments. When the dates will not meet, a rent-back on the house you sold is the usual fallback.
What is a rent-back or post-possession agreement?
A separate written agreement that lets the seller stay in the home for an agreed period after close of escrow, usually for a daily fee. It covers the fee, a deposit, utilities, insurance, condition and what happens if the seller stays too long. Arizona REALTORS says these agreements are not recommended and carry inherent risks, and advises both sides to get legal and insurance advice first.
How long can a seller rent back after closing?
It is negotiated between you and your buyer and written into the post-possession agreement before you accept the offer. Your buyer's financing can affect how long they are able to agree to.
Can I make an offer contingent on selling my home?
Yes, on the Arizona REALTORS Buyer Contingency Addendum. Your purchase can depend on accepting an offer on your home or on your home's pending sale closing. Sellers see it as a weaker offer, and many will not accept it or will only with a short deadline.
What happens if the seller gets a backup offer?
The addendum sets the notice and the deadline. You can keep the purchase by waiving the contingency, with written documentation from your lender or evidence of funds on a cash purchase. If you do not waive in time, the contract can cancel on the terms the addendum sets, including what happens to your earnest money, so read that section before you sign.
Can I use a bridge loan or HELOC to buy before I sell?
Both exist. A bridge loan is a temporary loan with a term of 12 months or less, often used to buy before the current home sells. A HELOC is a line of credit against your equity, usually at a variable rate. Ask your lender whether you qualify and what it costs.
Can I close my sale and my purchase on the same day?
Yes, and when the dates work it is the cleanest way to move. The sale closes first and its proceeds fund the purchase. If the sale is delayed, the purchase is delayed too, so I set the dates on both contracts together.
