An enlightening example, is the owner of a corporation diverting unreported corporate funds to a safety deposit box, mixing in his own funds, and then spending $10’s of thousands of the corporate funds for his own personal investments, and use.

A door that doesn't open is probably a material defect (safety issue, if nothing else). 

The typical buyer is 1031 exchange, retiree, estate planning, foreign buyer, or ultra high net worth that wants cash flow but safety so will take reduced yield for quality.We stick to strong suburban to urban locations.

My soft structure apartment needs to have the carport reinforced for earthquake safety.  

If you've done your math, added all of your safety margins, made an offer, and the deal doesn't work out, on to the next!  

I was able to teach them everything from using a compound miter saw, to proper safety gear, to applying hands on knowledge when negotiating with subs. 

Look at comparable properties, prioritize what needs to be done.  

If I no longer feel safe at the complex I am currently living in is there anyway I could terminate the lease early?

I have a full time job working for an Engineered Wood Products Company as a Safety Manager.

I would bump up maintenance and cap ex to AT LEAST 10% each, more if want margin of safety.
