I also accept checks.

I think you may start in Husten with a duplex, check it out do the work, and see how it will work, then all you need is to duplicate that in another city with 3 or 4 units.

Hey Eva I checked that out.

I thought that, at least I could deduct property taxes, Interest, PMI and Home owner's insurance.I am being told that, basically, we have to treat the entire rent check as taxable profit because of our income.

Even though you're in TN, it's worth checking out. 

Hi John, would recommend checking out comparable properties on Furnished Finder as @Joel Bongco said.

If you go the new home route, check the rules on resale and if there is a right for the builder to purchase it from you or a minimum time before you can sell it. 

(I got it in the contract for 92K, 4 yrs rent to own later when closed i was suprised when i checked to find the value at 130K.) 

If Airbnb has confirmed these are Service Animals I wouldn't make any waves and see if there are any issues after they check out.
