It really depends on if people in the area are actually staying in College Park.Delta employees may house their employees there for training, but if Delta offers free hotels for their employees during the duration of their training, then that would suck for an AirBnB business if that is the main source.For me, the main thing is to find out why people look for hotels in the area (jobs, schools, constant conventions), and if there is any demand staying outside of hotels by looking at other people's AirBnB calendar.

Call property managers in your area (old house) to see what you can get and the demand for that type of unit in that area.

The tenant answered the door and said just a second and she would let us in but she had to put her large dog up, but for the next 15 minutes, she did not respond to the owners repeated demand to let her in and never came back.

We recently had a furnace break two weeks ago and the renter is demanding a refund.  

I realize you aren't in that same arena but it speaks to the demand for additional MF housing. 4) The best deal is one that you can add value.

That should give you more confidence since there would be no demand for those deals if they were not good on paper.

My long winded response demands that I apologize but I hope this is helpful.
