Filthy, verbally abusive landlord
Pros
Pretty building from outside
Cons
The owner is a (literal) hoarder who lives in the basement surrounded by rats, cat shit and sigarette butts. The first floor is occupied by her nephew and a rotating cast of mid-20s drug addicts who yell and party all night. Truly, truly hellish.
Advice to the owners
Fix the floors. Evict your nephew and “roommates”. Don’t yell or curse at your tenants. Just sell the place.
