Backup offers.

They seem appealing to buyers who missed a house they wanted.

However, they are 99% of the time, a bad thing to do.

Why?

1. It ties you up. You have an accepted contract on a house contingent on the primary buyer’s contract falling apart. Should another house come on the market that you want to make an offer on, you have to rescind your offer IF you have verbiage in your contract that allows you to do so. If you don’t have that language in the contract, you are stuck. You are missing out on houses you could get right now in hopes that the sale of one you previously missed will fall apart. This is a recipe for never getting a house.
2. You are really helping the seller more than yourself. Think about it from the seller’s perspective. You are putting them in a spot where they have two people wanting the house. If the primary buyer asks for repairs after a home inspection, the seller is just going to say “Look, I’ve got a backup contract. If you want this house you’ve gotta do what I want you to do. If not, walk away and I’ll just let the other buyer have it.”
3. You are going to pay a premium. The seller has no reason to accept an offer less than the primary contract they already have. If you’re a seller with an accepted contract for $400k on your house, would you bother with an offer for $390k? This means you are most likely going to have to make an offer stronger than the offer they currently have with the primary buyer.

When is that one single time when it might make sense? If the house is 110% exactly what you want and you are not going to be happy with any other house. If that’s they case, make that backup offer. Pay too much for it. Give the seller all the power. Pray the sale with the primary buyer falls apart. Then wait and see what happens.

If the house is just a really nice one that you liked a lot, just keep looking. Another one always eventually comes on the market. Oh, and remember, the best way to not have to make a backup offer is to have been the strongest offer the seller got when it was on the market. Beat the other buyers when you have a chance. Be that primary buyer that another buyer hopes will not be able to close the deal.
