what sites would you suggest using for this?

There is usually a clause in the P&S or addendum to the effect that if the seller needs time to remove any defects in title, deliver possession or make the premises conform, you agree to give them an extension and if they are unable to perform by the expiration of the extension, the seller will refund buyer's EM and the contract will be void with no recourse to either party.

Take the time to check out the site and provide value to others where you can.

Good luck and I hope to see you taking action and crushing it here on the site soon!
