Tenant created workorder - Cracks on the wall

[Mayank S.]

My tenant just shared the pictures with my PM about a crack on the wall which has increased over the past four days. My PM in turn has forwarded me the pictures and asking me what action would I prefer them to take. Attached are the pictures. I don't have much of a clue really what should my next step be? I see these type of cracks at my house too and never concerned me. May be it's nothing...However would appreciate to hear from seasoned landlords/PMs/REIs on my next step. 

Any advise is appreciated.

Check the foundation. If it's serious you will have new and noticeable cracks in the foundation. If it's been slowly settling and the drywall/plaster just finally cracked it may not be a big deal. So check foundation, keep a close eye on it for a little bit, take measurements of the crack and anything you can in the foundation to track changes. Also check around the foundation to make sure gutters are good and water is running off properly. If it's been super dry and the earth has pulled away from the foundation followed by heavy water that could cause problems. I've built a rehabbed a lot of homes and this itself doesn't concern me, but I would want to quickly go check the foundation to make sure it's not a bigger issue.
