If you're interested in a property that's listed with an active contingent status, you may still be able to make an offer. While the initial offer will take precedence if all the contingencies are satisfied, making an offer can put you at the head of the line if the original deal falls through.
It won't hurt anything to look at a house listed as contingent. Nor will it hurt to submit a backup offer, if possible. That said, you should anticipate the original contract going through to close.
You can still make an offer on a house labeled contingent or pending. However, when a property has one of these statuses, it means that an offer has been accepted, so the sale is in progress. The deal hasn't been finalized, so it still gives you an opportunity.
If the offer hasn't been executed by both sides, the seller can totally keep showing and negotiating other offers. If it has been executed by both parties, they can continue to entertain other offers as ``back up'' offers, in case the original offer dies for one reason or another.
Contingent offers have higher rates of falling through and as a seller you very well run the risk of losing out on non contingent buyers.
In most cases, putting an offer in on a contingent home is an option to consider. Although it doesn't guarantee you'll close on the home, it does mean you could be first in line should the current contract fall through. Putting an offer in on a contingent home is similar to the homebuying process of any active listing.
