I agree though with everyone, best bet is to buy him out asap so you can do what you want with it to upgrade it and then decide.

But I am not betting on that.

So, you can add SEC violations to the list of things he did wrong.Since you now have the notes in your possession and are actively working them, that might have changed now however, I would bet that if you contacted the SEC and told them this story, they would probably take action.

I bet title was in the name of the company and each investor got their interest in a partial assignment.. we used to do 104.1 endorsements. 

Someone local, who knows the area and how properties move is the best bet for the most accurate answer for you. 

DSCR is your best bet.

The items you'll need to track are:Date of ExpenditureVendor Name/Tenant NameAmountCategory of Expense (look at a Schedule E to get this)/ or Revenue Type (Rent, Deposit, Utility Reimb, etc)Property (for when you have multiple properties.Put it in a nice column format like this:Date                     Vendor/Tenant                Amount                      Category                  Property1/1/18                   Joe Smith                         $1500.00                     Rent                           123 Main Street1/5/18                  Home Depot                   - $20.00                        Repairs                       567 Oak StreetSo that when you share your spreadsheet, they can filter for what they want. 

I think it’s a long road.I’d just be willing to bet handsomely that occupancy is a huge challenge, revPAR suffers, and asset values fall in many STR markets over the next few years, and fear that the Smokies may have among the highest risk.

If you want 10% returns you might have to look in another market, but if you want to park some money in a solid property, as long as it generates enough to break even after all expenses, taxes, etc. to allow you to hold on to it for 5-10 years I'd bet it will do better in the long run than a 10% cash flow property in a lower end market. 

Most homes for sale on the MLS are not looking to go with seller financing, in my experience usually you get those types of offers from the seller looking for buyers that want seller financing which is few and far between.I think your best bet here could be to offer sub2 but even that is a far stretch.
