Trying to avoid paying 3 closings for One Property

[Adam Soyak]

The seller has requested a 21 day mortgage contingency on the offer that I originally proposed as a 30-day conventional loan.  After speaking with multiple banks, obtaining that 21 day mortgage is slim to none.  So, I got creative and have some friends and family assisting in funding the initial purchase of the property for cash.  One of the family members is requesting their money back within 30 days (asking for no interest, VERY nice family member).    So right now I am looking at 3 closings and wanted to see if I could get any advice on how to avoid because of the cost implications.  And is there anything else I should be looking out for.  (ie. Title transfers, etc.)

First closing-Cash Purchase

Second closing-Get mortgage on property to pay family member back

Third Closing-Selling the property once Flipped.

Thank you!
