@Truong Vu You have some valid concerns, but most investments, whether for your personal use or long term holding property is usually about leveraging what you have.

There are 4 to 5 houses on this private drive way which is paved like a street but is not maintained by the city and most if not all of these houses belong to family members in the estate.I have to concerns about buying this property and please fill me in on your thoughts and opinions.  1. 

Carrybacks are super dangerous.. but...

This might be an unfair perception of folks who open carry - but it is still a real concern, and one which is not going to help you.

Is that dangerous?

It really is a dangerous business.   

The dangers of mold are dramatically exaggerated, and sometimes completely false.Get a professional company that handles mold remediation.

There are multi-million dollar houses that you can walk just a couple short blocks and watch the neighborhood get pretty rough and potentially dangerous.

My dad once said if it isn't dangerous it wouldn't be fun. 

If you spend it now, you lose your leverage for the rest of the lease, and you'll have nothing to handle unpaid rent, cleaning, or repairs after termination.You are starting down a dangerous path.
