Rentals are obviously not as crazy as peak COVID times, however even in winter we're still having most weekends booked out with the odd midweek booking here and there. 

Sure, they play pot odds and ensure they only take on good cases.So... it depends on your W-2 hours spent... and your tolerance for pain (risk).

From what you laid out, a bank statement loan might be your best bet.

Lending: You bet.

HELOCs are variable rates and it's highly likely that they'll actually be LOWER in the near future, why not bet on that?

I lend 40:1 odd's of some action of significance to attempt some manner to flip polling #'s.

What are the odds this home made the perfect rental?

@Dennis Carter IINot an attorney but I do not see why title insurance would cover this as there was no written agreement that was missed it was verbal - there was nothing they missed.Sounds like your best bet is to drill your own well.

However, if improvements were substantial then indeed a Cash out refi will be your best bet, and depending on your credit score, and cash flow you will be between 75%-80%. 

If your debt is student loans at 6-8% interest your best bet is to pay them down/off as fast as possible as most investments will achieve a similar result but that is gross (before taxes) not net.
