But the main thing is...are they COLLECTIBLE.. and if there is any doubt in your mind, get a CO-SIGNER.Nancy Neville

Here is the main reason why... when you sell the property that's the last time you made money on that property. 

Private lenders are all pretty much stated income - we mainly look to see that your strategy/plan is sound and you have money in the bank to make it happen.

If this unit shares the address and the utilities with the main house then it would certainly be considered a 1 unit home. 

I mainly looking to get into BRRRR properties or just buy and hold rentals for now but definitely would like to get into flipping once I'm able to move back to Pittsburgh.

You can definitely read books on rental properties in general, and maybe a little bit on management (out-of-state you'll likely be needing to manage the property manager as your main duty).While I can't think of books specific to it, there are still lots of resources.

Another option if the main reason for you wanting to exit these investments is that you don't want to do the repairs yourself any more would be to hire a property manager to handle all of the maintenance, showings, and rent collections. 

Two main reasons. 1 is we make money a whole bunch of ways as I described above. 2 is you cannot keep all properties as you will run out of capital.

Do you have any tips on how to prevent renters and cleaners from taking all your extra supplies (like how people take shampoos at a hotel)?

I'm renting out a condo and a prospective tenant asked me if I would supply the air filters for the unit's HVAC system.
