The problems you mentioned are the exact things I warn people about.

I will warn you, the DOB is no joke in UC.

I could have gotten in depth knowledge by internet or just going to the library and renting some books for free.Maybe I'll post this on their goog map so when people gps to their office for the sales pitch they can be warned right away.

He wants me to write a special clause in my lease warning the tenants of this and suggesting that they subscribe to the area fire protection service themselves.How would you handle that?

There are plenty of things to warn about on this loan type and structure. 

Violent crimes, assault and sex crimes are certainly a serious matter.There was a case where a woman fired a gun at her abusive husband as a warning that wasn't even close but in his general direction.

Word of warning: Current or potential Airbnb guests might ask to pay you cash in person instead of booking through the website.

Of course, even if you win, you then have to collect, which is not easy, either.A stern letter from your attorney threatening action might get some response from the seller.I have to agree with @Ericka Parrott. 

The truth was, I never supplied those figures and only after several stern notes to the publication did they cease utilizing my name and reputation to their advantage.

Any advice or warnings?
