I personally have a very strong reputation in the Detroit market as well as here on BP.

I don't like them personally.

I do have a wholesaler wholesaling me the deal and I will in turn wholesale to another person.

After all was done the neighbors apologized for over reacting and I was now out $2400. eye roll.My personal thoughts are the danger is over blown.

Until the foreclosure is complete, the owner is the only person who can sell this property to you. 

I recommend styling your tables, adding a theme and just making the property have more personality.

The answer to that question depends on your personal wants, needs, and goals for you and your loved ones.

But you are not liable personally for. 

Speaking from personal experience!

Diversity of portfolio is good for maintaining capital but if you're having success in one area I would continue with it until you have enough capital that needs to be diversified and then seek out professionals in those spaces who can benefit from helping secure your capital in other asset classes, personal opinion!
