This place always amazes me with the diversity of knowledge. I need some CSI type science knowledge. I jumped back into being a landlord with the purchase of a 6 unit building this summer. This unit had a long time tenant who the agent said wasn't 100% "there" mentally. Her parents would send half the rent, etc. She had a little boy in this place. She moved out 10/31 and though the place was as dirty and gross as I've seen, it cleaned up remarkably well. Two cleaning ladies and a full day later it is rent ready.
Except for the smell. There is a lingering odor. Best described by me as a cat litter box that is full. We can't find the source. It could be the kid was peeing somewhere. Possibly just years of no cleaning has seeped into a porous surface? Walls are plaster as it was built in 1912. Any suggestions on how to track this down or deal with it? There are no obvious stains, hardwood floors or tile throughout the apartment. I've been on hands and knees sniffing in closets, etc.
