Virtually all basements are going to have water concerns, whether from high water table, moisture attempting to move from soil to concrete/concrete block to air, actual infiltration from walls, etc.

A house doesn't go from 70 to 50 in a few hours unless they open their windows to enjoy some fresh air.

I was looking at Air BnB but I am not sure if my property would be profitable. 

Tenant moved out 3 days after discovery into air-bnb that was 3 times rent and expected us to pay.

I’m active duty Air Force retiring next year.A great way to start is using your VA loan.

Over time, you will be losing out on revenue and just prolonging the inevitable move out when they can no longer pay the rent.  

I also have no air conditioning.

Not to make a million dollars on an assignment fee or to hold the property hostage for a prolonged periods of time.

Also includes all appliances except clothes washer & dryer on both sides as well as air conditioners/furnace as you'd expect. 

He wants to then park his RV and them Air BnB it out.
