How do I not lose my buyer????

[Kate Weinberg]

We were all set to close on the sale of my flip until my buyers lender decided they needed a few more conditions cleared: 

It is a high interest (8%) jumbo loan with 10% and low 600 credit (640 maybe?).  They have been gifted some money for 10% down payment from parents and that has been seasoned for over a month.  At the last minute, the lender then decided they needed 2 year rental history.  This family travelled on and off for 2 years overseas so do not have a 2 year rental history.  So they said they can waive that requirement but instead, now need 6 months reserves ($35K)  which they do not have.  They do not have retirement accounts.

Any thoughts on how we could proceed and still close timely?  ie creative financing, difft lender type, etc.

any insight is very much appreciated....
