What’s the purpose of the loan and what is the collateral?

The sellers had put so much pots, plants, planters and shrubs out that I thought there were too many plants/planters that would require a new owner to upkeep.After a few potential buyer tours/showings, the owner heard all the comments (via the security cameras) about how there was a "lot going on with the plants and stuff out front".

Did you try a local CU or bank for a construction to permanent loan?

The area has certain advantages like shelter from regulation risk (pretty much as low as anywhere in the country if you buy in the approved STR tourist zones) and long term security (people aren't going to stop going to Orlando anytime soon). 

That is part of the problem with a lot of companies (I am not knocking insula as dont have all the info/facts just stating how the business works), they engage brokers to get them loans and the brokers collect a small fee. unfortunately many of the brokers may be similar to real estate wholesalers - have little to no experience. 

Personally, I'd cash-out refinance into a 30 or 15 year loan.

I was considering having a lawyer draw up a baseline loan doc and make tweaks to it on a per loan basis.

Private lenders or even creating a small syndicate with a group of investors might also be worth exploring, especially since you can point to your uncle’s track record and your own experience managing rentals as a selling point.If timing is tight, you could look into a bridge loan to secure the property while figuring out a more permanent solution.

Consider all the things that could go wrong and see if the lease addresses them: unauthorized pets or tenants, early termination, security deposit, lease violations, late rent, eviction, lawn maintenance, parking, etc.5.

Name detection is via loan signatures.
