Julie... It sounds like the new house may be well below market value? If so, maybe offer the owner $57,900. for it if he will give you a 6 month option at that price? He makes a few more bucks, you get the house with very little difference in payment. Or... Try some other banks and lenders, but tell them you are buying it as an investment. Don't mention selling your house? Or... If there is a Realtor involved? Ask them if they know a lender that could help you? I've even had Realtors delay their commission AND lend me some cash to close a deal! They often know mortgage brokers and good bankers... helps them make many sales to have connections. Or... Get a $20,000. second mortgage on your house? Then buy the new house with $20, 000. down and get a mortgage for $35,000. (with no pre-payment penalties) and buy the house. Keep looking around at other banks & lenders... Someone wants to make you a loan, you just gotta find them.
Obviously, some of these ideas could put you in a double payment situation. If you can handle it, sometimes it is worth the gamble, if it is a good enough deal? And, you could rent the new house to help make it till you sell yours. I have done some pretty wild things to make a deal work in the past.
I hope you get it.
