This location is PRIME & safe, it's a 10min walk to downtown Durham, a 1min walk to their Physician's Assistant School, across from a beautiful park, on the same street as a bus stop which helps students/guests without cars, has a HUGE backyard, it's the most expensive zipcode in Durham, the surrounding homes are all well maintained, it's a historic neighborhood, there are townhomes being built a block down starting at $650k and more being built two blocks away starting at $800k.

Any broker or individual investor who values a non-commercial asset using commercial metrics are only showing their ineptitude. 

The outside of the house looks well maintained and cared for, not in obvious distress. perhaps there are foundation issues, but it's block and beam so I'm not entirely sure how difficult that is to fix. it has window units but lists as having central air, possibly it's broken?

To be successful with this, I want to focus on working with one individual/company at a time.

They have three kids in high ranking public school half a block away.  

I don’t know what causes the concrete blocks (walls of the house) to crack like that and am worried about an underlying issue that will lead to expensive structural problems that I will be liable for if I purchase.

At a minimum, you need to verify their identity and their criminal record.I generally combine their income to meet my standard of 3x the rent but if there are three or more unrelated people renting together than I require each individual to make a minimum 2x the rent.

I have had a 3/2 property on 37th Street about a block from the beach.
