Neal and Jean-Marc were supposed to secure construction funds.

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. 

Yes, very interested in investing and would love to own a few multi family properties, here in state.My immediate goal , so far, is finding investors to secure my proposed properties.What's your strategies?

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). 

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".

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.

@Chris Seveney @Nathan Gesner The owners offered to cancel their lease and return their security deposit in full.

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

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

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