Stick to my guns and keep using my 25%?

@Marc Alexander rates are low so that will help... you are looking at the right numbers as well (I calculate mine with just debt, tax and insurance and only invest at a 33% return... knowing that my goal does not take into account vacancy or repairs so I come in below the 33% but always above the 20% mark you want to hit)Look for and buy fir cash flow... stay away from real crappy areas (like you can get great ROI in south side of chicago but you have to carry a gun to collect rents) and make sure tenants are “good” people....

I WAS by no means a security camera enthusiast.

Or, just stick to my guns and charge him for the repair out of the security deposit, and bill the small difference.

Your notice was more than sufficient and you need to stick to your guns.

The job is laborious - climbing around, measuring, taking photos of comps where a lady comes out with a gun; but also numbers, stats, knowing all the houses in a city from previewing or prior work @Robert Leitner you are kind not to blame your broker, and a real AVM desktop should nearly have been cheap digital information.

Guns that they wanted were pistols. 

New lighting and faucets added throughout, all wood floors were stained in gun stock, and all interior walls were repainted with a darker gray in bedrooms and a lighter gray in common areas with a bright white trim.

However, I have heard of people purposely shooting their guns at night too in the area to keep housing and rent prices down and scare away people.  

They didn't call their handyman to heat the pipes up with a heat gun, they just let the pipes sit there until they defrosted.
