I have calculated an average of around 20% of gross rent in repairs, credit losses, and other miscellaneous losses from the building getting raided by police to burning down garages and many other crazy things.

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.

If it turns out these tenants are doing something illegal and get raided, I can't afford to lose my truck and personal items.

My exterminator recommends:1) spraying the apt and outside a few times (3-4 times)2) pulling the appliances out of the unit and spraying the exterior with a can of raid, especially the back of frig, until you empty your can of raid (1 per appliance).

Then there is Lexington ave, where I was caught up in a drug raid several years ago while knocking on doors.

Lots of questions to on the DC real estate commission, DC guaranty fund, DC grievance process.Also be aware that the DC mayor is proposing raiding the DC guaranty fund. 

They have tried raid and everything else but the ants kept coming back. 

I have had stabbings raids shootings and murders at some of my properties.

First of all, the use is still technically illegal, which is why Toronto dispensaries are regularly raided by police, and they keep very little cash and product on the premises (they have multiple courier runs every day).1.

Not even after the SWAT raid.
