Also hearing about FHA, but does not seem to be an option with our lenders, have found 10% down, but not FHA.

Does anyone know any other options out there ?

Zero credit facilities or mortgage options and investor lethargy.

ie. single family, small multi-family, large multifamily?

The Rev Share from agent attraction is an OPTION that we have to make additional passive income on top of our commissions! 

Is there anything I can do to ideally get them to not list the house and sell to me, I’m assuming there might not be many options, especially since the sister and I had agreed on a price that was below market value given I was planning to invest money to remodel the home and was planning to honor his wishes of not having the home knocked down to make a townhome or new home.

Take all that out of the equation and you have two options.

I would get ready for other options as well.

I do think remaining debt free (aside from a mortgage) is the best option. 

STR that do the best have a target audience based on the the surrounding options that improve the vacation experience.
