I sold my 1 family house and after many prospective buyers were unable to get mortgage finally after 7 months found one who was able to get mortgage. After searching for my new house found prices are much higher than when I first started my search and conditions really bad. Buyer now wants to move in ASAP because his mortgage will expire in a few days, however was able to extend for 45 days. Have not closed yet because I have nowhere to go. Is there anything I can do or will buyer be able to sue me.
