The person who is the good debtor will get dragged down by the bad debtor / deadbeat; when this is the case, the good person's credit report will have older years showing no derogatories but the occasional ding in more recent times, showing a gradual decline that can start to accelerate as more time passes.As a few other posts have noted, finding out their past history of paying rent is your best indicator; if they had trouble paying rent to past landlords, it can be expected to happen again.Lastly, I would add that you have to have a good understanding of debt to income (DTI) and how to calculate DTI and what a bad figure for DTI would be.

Hello, For the last 5 months or so I have been reading as much about real estate investing as possible, trying to analyze deals in my area and save up as much money as possible; however, I am stuck between trying to pay down debt or make the minimum monthly payment on my loans.  

People want to succeed but then have high debt or cost of living and say they cannot go full time.Maybe you could do another kind of work in commercial that pays similar to what you are doing now.

With a syndication you would typically become a part of the LLC as a limited partner and receive your payments through either a debt or equity split.

after i pay all the debt (tax water and cc bill) im still getting a good deal for the house but im not sure how to actually pay all the debtors??

If they know, and tell you - then at least you know up front that they aren't trying to deceive you.If they say nothing bad, and you see bad stuff - then you have good reason to be concerned.If they act like they don't know what will come up - that is one that's tough to believe if bad things show up, because the bad things usually lead to the creditors contacting the debtors many times trying to collect.

I have a family member who has found themselves deep in financial trouble and they are wanting to sell their home to me at a massively discounted rate to pay off their debtors.

Probably need to know how the interest rate on the debt compares to the return you can make on your real estate investments to know whether it make sense to pay off the debt or use that capital investment purposes.

@Daniel Smith  well  you have plenty of time and if you have a good relationship with the debtor like it sounds like you do first step is1. 

You can also pay the debt like a responsible person, and that will erase the debt.  Or
