He scammed a lot of people out of a lot up-front of money.

Did you close this with a hard money loan?

@TJ Woolum - save your money (many will be glad to take it), rather invest your time and energy  to connect with the right people!

Just remember you are spending time and money to improve a space that isn't yours and you're not able to take the improvements when you leave, ownership should have some skin in the game especially in a new build.   

Value your money more. 

At least weekly I think about the the fact that someone else is going to work to give me 1/3rd of their money.

Roger that @Brandon Vukelich, but I don't see lenders adding STR revenue to the actual property valuation in the future.

While hard/soft money lending is outside my area of expertise, I'd like to discuss a potential levered IRR scenario.Consider a $2.1 million property acquisition (10 cap) using a 1031 exchange with a $715,000 down payment.

If we move forward with transferring the deed, we would like a way to guarantee to my father and my sister: a) some return from investments made with money taken out of the house, and b) equal shares in the house if we sell in the future, or a buyout path for either of them.3.

Most can't and that's where money is often spent unnecessarily.
