Lots of houses have flood designation amendments if they are up against little creeks, so they wouldn't disclose any issues because they had their boundary inspected and ruled OK.

At today’s rates, most properties at high LTV are negative even with 1% rent to value ratio   This implies the 1% rule is far from assuring positive cash flow   Good luck

You can probably find an online link about how extreme temperature changes are not the ideal way to heat a home and cost more in the long run.I don't know what the local rental rules are where you are, but look them up and see if you can give her notice. 

There are rules to follow!

I suspect they are using someone else's identity or hiding something negative from their landlord.It is not uncommon for people to have good credit but still have an eviction or other problems with a previous landlord.

It works almost identical to a car loan.

I’m trying to utilize 1% rule and it’s tough with current market 

If so, you've violated S8 rules. 

I try to not have a lot of "rules", but writing out some expectations can go a long way in resolving conflicts down the road and hopefully not ruining relationships/ friendships.happy to go over more specifics with you if you'd like!
