You need to ask ages so you know who all the adult applicants are.You ask the birth date and take a copy of their DL for the applicants to establish their identity correct?

@Hattie Dizmond, thank you for confirming Steve's identity.

With that being said, the types of deeds should be quite similar if not identical in most states; just depends on local practices as well.  

This is the information I've researched & come up with so far:The city has assessed the home (btw it's a 2 bed 1 bath duplex) for $116Zillow assesses it for $135There's an identical duplex (needed no repairs) two houses down that sold for 83k in '98 & 80.5k in '12.

I have asked an almost identical question before and have had the same concern.I guess I just decided that "it is what it is" and I won't make it overly obvious that I'm writing the blog.

If it is identical to the rented side it is easy to figure.  

It means no background or credit check and it is possible you are renting to someone with a totally false identity.

Comps are hard to come by - there is a sale for 60k, & another for 90k in 2014 for identical units on the same street, and a 2016 sale for same type of duplex at 130k on the same street so the price is reasonable especially for the market in 2017 for the area. 

When valuing commercial (multifamily) the formula is similar, but not identical to looking at single family.  

Please do not disclose anyone's personal identity.
