It mentioned things like smoke detectors in sleeping areas.

Also, requesting owner bring units up to code concerning smoke/co detectors.

Here are a few: # 10 year smoke detectors, flooring (7 years), paint (5 years), fridge stove garbage disposal washer dryer (7 years), hot water heater (10 years) HVAC (10 years) roof (20 years), plumbing system maintenance $500/year,

HOWEVER  ...... when I  sent a contractor over for a few minor violations (smoke detectors), electrical lights out..... 

Either  1) you will get no loan whatsoever, or 2) It is some BS combination of "trade accounts" credit.....Office Depot, Home Depot, and other misc useless businesses......Not a cash line of credit.Once you qualify for any kind of business line of credit, there will be No upfront fee, and more importantly it will be because you have established an Actual ongoing business that shows a profit, and consistent revenues over a few years.Time to turn on your BS detector.

Install motion detector lighting as well.

My worst experience was driving to my three decker at 2am to try to figure out why the smoke detectors kept all going off at the same time in the middle of the night.

They've rewired the electrical and installed new smoke and fire detectors.  

I bought 3 homes (2 in Rochester, 1 in Brighton), that only needed me to change the locks and install smoke detectors (and a few more minor stuff).

Those aren't exactly something the Consumer Financial Protection Bureau has made optional...My BS detector is starting to activate.
