Divorce,death,bad tenant,behind on payments and facing foreclosure and bad credit?

I am newbie here who has heard real estate is a great way to build long term wealth.I would like to get started but with a bad credit  history I find it extremely diffcult.Still the financial longevity well not only be statisfying but the peace as of mind will put me at ease.

But outside of these logistical issues, is there any gaping hole in my logic as to why this would be a bad idea?

Thanks Account Closed for giving quality advice n response to post BP members may put on here.

Some people will say, "Take out a quality Insurance Policy and you will be protected."

It's also hard to tell how bad it is, given that it is a ton, maybe its 70% damaged, who knows. 

I should add that I am really not looking forward to the idea of showing the house again and searching for quality tenants, it has taken me a very long time so far.  

I have 0 derogatory marks and great credit other than bad dti due to some credit cards. 

If you say a property needs $10,000 in rehab, and turns out it needs $30,000, your reputation will look very bad, and no one will want to work with you.

Why not make the determination of tenant quality after your close?
