@Maciej G in my opinion you have gone above and beyond with attempting to mitigate the situation.

Or it simply to find a city where you can rent an investment property full-time on Airbnb?

Your insight into a particular market, combined with the expertise of your partners, will be far more advantageous than simply following trends.

Then the next day I go through and respond to everyone simply saying “yes it’s still available.

Most investors opt for the skeleton versions that truly miss the mark and lead to convoluted amended and restated agreements that cost far more to correct than simply paying for the agreements to be drafted by a professional at the start. 

I currently live next door to one of the areas most popular restaurants and my vehicle is somewhat distinctive if you notice it simply because no one else in the area has one, not because it’s an expensive sports car or something.

If you are using their money for a down payment, are you really planning on renting it to them in a traditional sense or simply having them pay for the mortgage, insurance, taxes, etc (ie you won't be renting it at market value more you are buying the home for them and they are making all of the payments and repairs?

If you are buying a turn key and do not expect to take cash out for a few years just gauge that on your prepayment penalty years.Rates vary depending on credit scores, LTV, DSCR ratio, Loan amount, Property type, number of units.Good news is rates have been dropping so DSCR may not be a bad option if you buy and simply refinance in 12-24 months.

Feel free to simply vote; or, explain your selection.

Let them know despite repeated attempts to collect the money, it is not forthcoming and that you will be starting the eviction process for non-payment of rent...then hire an attorney who specializes in evictions and get the process started.
