Other than that not too much you can do, the only alternative post-closing would be to offer cash for keys for someone to move out quicker, but if it's short notice to vacate period like 15-30 days than it's probably cheaper to wait. 

What terms are they offering you?

I am not even sure if the villages offers this type of real estate in which we could “house hack”.

Feel free to dm and I can put you in touch.Also, please have a licensed and vetted contractor walk the property either before putting an offer or during an inspection period when you can back it and get your deposit back.Skepticism up front is always better than regret later.

I even had a wild hair to make an offer on the marina I was managing at the time.

Maybe offer to pay a portion of the balance contingent on completing the work or signing a waiver to avoid the lien.

I'm going to offer a different perspective of looking more at the asset instead of cash flow on paper.

It was listed on Zillow for $110k and we made a low ball offer at $90k, ended up getting under contract for $95k.

@Vernon Welch II most tenants offering to pay their rent upfront are trying to compensate for negative qualification issues.NEVER override your screening process just because someone offers to pay several months upfront!

Rates will be a little higher (5%/6% range) but the cool thing is that you can often find these on 30 year fixed terms unlike the short term balloons the local bank would offer.
