The real issue is if they are going to trash the house before you take possession.

At a minimum you can add to your rental application the questions: "Do you own or possess guns?

I have properties in NC, SC and one in NYC the one i would like to bring up is in SC I bought a fourplex all rented leases in place BUT all four leases were cheep the apartments all looks like Vietnam going through the DMZ bombing raid. so I sent all 4 tenants a 30 day notice that they are to move within 5 days after each lease has ended we rehabbed the entire building as each one left pulled the carpet and got started. we have now finished half the building invested about $30k and re-rented the two finished apt's each went up by $250 a month plus pet dep and extra rent for the pets. and this took all the RIF RAF out and even got a thank you note from the local police and the mayors office for what we did. now in saying all this SC is VERY, VERY Landlord Friendly no rent by the 5th pay $40 bucks for first notice to pay or remove no rent still they have 10 days to pay or leave after that 14 days later the sheriff;s office removes the tenant and retake possession.

However, it would handle spaghetti and fruit peels just fine.Haven't decided if disposals are possessed or just channel the personalities of teenagers.

Probably the first thing you will think of is adverse possession. 

I took possession on the first of the month and collected rent from the tenants that same day (8 units).  

If he is ever behind, take him to court to get possession so you can file the WRIT if you need to.
