You may get a different loan that requires less down, find a grant or down payment assistance, ask the seller to pay closing costs freeing up some of your cash, buy a less expensive house, save up some money, sell something for additional cash, ask a relative for a gift.
There are 7 options, would any of these help? I also agree with Mack, having money left over is really important. Your inspection will tell you what is working then, not in 30 days, 60 days or longer. If a roof leaks, furnace breaks plumbing leaks you may be in a difficult position.
