We are still in it for the long haul, even after fires, drug busts, shots fired, dogs, cats, arrests, abandonment, lies and several other things.

It just alleviates some pressure for the Landlord. 

I make sure that I explain risk and help alleviate any anxiety she might have.

I just got through evicting the tenants from hell and I may have jumped the gun before acting upon my suspicions that my new tenants have been dealing drugs and would like to give them a little more time.

@Patrick Philip  you can alleviate all of your concerns by hiring a professional general contractor.

I have mobile homes that I do a similar strategy with that would alleviate a few of your issues.

You will also need to be very on top of your tenants in a rough neighborhood with potential drug dealings going on one of your units. 

For example there are pockets of Harrisburg where south of one street you have properties going for 180-220k range and north of that street properties are going for 35-55k and they are in rough shape with shootings/drugs nearby. 

The contractors need to pass a drug screen before they can enter the refinery. 

For example a national corporate tenant such as a bank, drug store or fast food chain on an absolute NNN lease.
