On paper sit down with a realtor and an REI investor and build a scaling template so you can see the path ahead.  

A paper list of work they would do to the property with price next to each work that is being done.

Additionally, you have many borrowers that do not qualify for your traditional A-paper mortgage from a bank and that will definitely not help, as they won't even have the opportunity to buy.

The master would pay for the business items like - car, office, paper, etc.

If the daughter is not on the lease, ensure you have signed papers from the mother herself if they move out early.Almost zero chance they will pay rent again.

it is a public information, once paper work is done, takes 40-45 days and anybody can find out how much you actually paid.

But I look weak on paper.

But most get sucked in by cash flow on paper.. when in fact its TRASHFLOW

If the STR is placed into service at the end of the year, they can use the paper-loss from the STR to 'potentially' offset other forms of income such as wages, interest, dividends, etc.Best of luck

On paper, the numbers work, it currently has renters in place, although month to month and one unit is actively trying to move somewhere else because they need more space.
