If your looking for a sustainable and turn key market, Omaha Nebraska is the place for you! 

One last question:Has anyone done the self sustainability test for 3-4 unit property insured by FHA? 

Your cash flow on each wouldn't sustain one AC let along the huge cap ex you're anticipating and fearing.3.

If you keep the place up, once you move out and decide to rent both units you already have it budgeted, self sustaining, and it has a savings account for fixes so depending on how long you stayed and what you fixed, now it can make you money or you can start paying your premium down every other month.

The cashflow on STRs is potentially much higher, so I would be more comfortable buying an on market STR in an area that sustains STRs.

Not getting into anything, but people need to realize we all need each other to live and stay sustainable.

FHA has sustainability requirements for more than 2 units.  

For example, if you make 100k your hourly rate should be high and focused on sustaining or growing that 100k.

A database of 200 people you see or speak to once a month has enough transactions within it to completely sustain your business.

Will you be able to sustain 2 to maybe 3 vacancies at a time?
