Of course, you're in FL and I'm in NY so there's a world of difference.  

We're looking at a rather large loan and I feel like we could go down a different road if this place is not legit.Thanks. 

I know it's not necessarily clad in stone but things are certainly different. 

I have researched the different kinds of loans for this but I would love to speak with any lenders or other investors in this area. 

I see HELOCs as low as 7.5%, so the difference is not that significant.

FWIWI use tenantalert.com  They used to be different name. 

Since your property has high resale potential, some lenders may be willing to work with you.Cash-Out Refinance – If you’re open to refinancing, you could take out a new mortgage for a portion of the home’s value (say, 60-70% of the $500K), and use the cash difference for renovations.Personal Loan – If you have good credit, you might qualify for a personal loan for part of the rehab costs, though interest rates are typically higher than secured loans.Partner with an Investor – Given the potential profit, you may be able to find a real estate investor or contractor willing to finance the rehab in exchange for a share of the profits upon sale.Your best option depends on your financial standing, timeline, and risk tolerance.

But now with the joy and headaches of non-metered units, trying to wrangle 3 different set's of persons into playing nice, etc etc.. 

Would it make more sense to move the money we make from selling to a different property that could potentially increase our cash flow? 

Putting 10%+ down with a different lender and getting lower points and interest is 100% better.
