What is a Backup Offer in Real Estate?
A backup offer is a purchase offer submitted on a property that is already under contract with another buyer. If the primary contract fails — due to financing denial, inspection issues, buyer default, or any other reason — the backup offer automatically moves into first position without the seller having to relist the property or negotiate a new deal. It's a contingency plan that benefits both the seller (reduced time on market) and the backup buyer (access to the deal without competition).
For real estate investors, backup offers are an underutilized strategy. Many investors walk away when they learn a property is already under contract. But contracts fall through regularly — industry estimates suggest 10-15% of residential purchase contracts fail to close. Submitting a backup offer takes minimal effort and positions you to capture a deal that every other interested buyer has already walked away from.
How backup offers work
The backup offer is submitted and executed just like a primary offer, with one additional provision: it's contingent on the failure of the existing primary contract. The seller signs both the primary contract and the backup offer. The backup buyer's offer doesn't become binding until the primary contract terminates. Until then, the backup buyer is not obligated to purchase, and the seller is not obligated to sell to the backup buyer.
Most backup offer provisions include: a specific time period during which the backup offer remains valid (e.g., 30-60 days), notification requirements (the seller must notify the backup buyer within X hours of the primary contract terminating), and the backup buyer's right to withdraw the offer at any time before the primary contract fails.
Why contracts fall through
Understanding why primary contracts fail helps investors identify properties where a backup offer has a reasonable chance of becoming active:
- Financing denial: The buyer can't obtain the mortgage. This is the most common reason, especially for properties with condition issues that affect appraisal or insurability.
- Low appraisal: The appraisal comes in below the contract price, the buyer can't or won't cover the gap, and the seller won't reduce the price.
- Inspection issues: The inspection reveals problems the buyer isn't willing to accept, and the seller refuses to make repairs or credit.
- Title problems: Title search reveals liens, encumbrances, or defects that can't be resolved before closing.
- Buyer cold feet: The buyer simply changes their mind and exercises a contingency to exit.
Strategy for investors
Submit backup offers on properties where the primary buyer is likely to have problems. Red flags that suggest the primary contract might fail: the property needs significant work (financing and appraisal challenges), the property has been on market a long time (suggests condition or pricing issues that scare buyers during due diligence), the primary buyer is using FHA or VA financing on a distressed property (strict condition requirements may trigger a failed appraisal), or the listing agent mentions that the primary buyer is "still working on financing" after weeks under contract.
For wholesalers, backup offers are particularly valuable because you can submit them at little cost (just the time to draft and submit) and potentially capture a deal when the primary contract fails. When a deal falls through, the seller is often more motivated than before — they've lost time, they're frustrated, and they may be more willing to accept a lower price to get the deal done quickly.
