Both names are on the original deed and every other document I can find.Any advice on information I should get or how I should proceed would be greatly appreciated.

Any documentation he has will help his cause. 

If there are too many renters vs owners traditional financing becomes nearly impossible or if HOA doesn't have enough money in reserves or enough liability insurance then its most likely that financing won't be possible.

Owner will pay all taxes and insurance on property until you purchase property at end of the term8. 

Figure your PM at 8- 10%, you will have garbage, lawn/ snow maintenance, water sewer, your taxes, insurance and loan payments. if there is common hallway or outdoor lighting, is it metered separately, if so, you will have that expense as well. 

The FICO is of no interest, but in a full report, you get the 30,60,90 day lates and that tells you everything IMO.As @Austin Youmans notes, it's also a future insurance :)

Unless I know the person doing that task, and their process and criteria are well documented, I'm reluctant to take on a tenant someone else has placed.

Also, when you're getting the property spruced up and marketed for a tenant, you'll be paying a mortgage, utilities, taxes and insurance with no rent coming in.

But then there is saved mortgage insurance because I brought the 20% cash but they are getting the advantage of it.  

While an insurance policy may cover your defense and potentially cover the actual damages of your tenants, it cannot and will not cover punitive damages.
