Certainly a solution that has the potential for much more family drama. 

There are always expensive surprises in this business and money is the only solution when trouble hits the fan.

What can I do to remedy a solution? 

I know there are other more creative solutions, but I'm having a mental block and want to get things moving. 

I’m ok walking away from the deal but I’m wondering if there is a creative solution to the problem.

If you don't have a rich relative, the nature of this project requires a complex solution.   

Another solution is too set it up lease and have her actually end on 07/05/2019, giving her time to move and you time turnover.

@Erin Onsager one solution I've used, and I know some other local investors have used here in Rhode Island (and likely all over), is to try to find off market deals where you can do creative seller financing, which is often at better rates/terms than you can get from banks.An alternate strategy is to try to raise private money from friends and family, again this is often at better terms than banks.

Tight timeline to craft a creative solution that requires some bank committee/board approval could be tough though.
