If the law does not, I'd offer them cash for keys, or not renew their lease. 

However, as we approach an election year I’m wondering if the time has come to say goodbye and move these funds on to another home.

For many sellers, you can just do a flat fee MLS listing ($100-$200) and hire a transaction coordinator (~$500) to make sure you are getting your paperwork done and everything is moving along correctly. 

Move on and cancel this week before due diligence ends.

@Winn Vu If she signed for it, maybe she lost it in the process of moving.

I would offer cash for keys, or not renew the lease, and reset the tenants in the building at the first opportunity.

It is one of the thing that can really hold back moving completely off of AirBNB and VRBO.

I moved to Columbus a few years ago (from Portland, Oregon which was super expensive) to become a full time real estate investor, and ever since, I've completed quite a lot of BRRRRs, flips, and own a successful rental portfolio here in Columbus Ohio. 

What key factors should I be considering, and what questions should I be asking?

Yeah I think a HML like @Logan Singleton mentioned would be a good move to call around or connect with a loan officer like him perhaps to see who would fund those type of numbers, but if you wanted to explore private money there's 100 ways to structure the deal.
