Are these Apartments a good deal?

[Nathan Yung]

https://www.zillow.com/homedetails/501-E-6th-St-1-8-Salisbury-MO-65281/2088137580_zpid/ I have crunched and crunched the numbers and they seem to good to be true. I am sure I am over looking something but would love some input or opinions. They consistently keep 7 or 8 of the apartments full at all times. Any help would be greatly appreciated. Thanks!
