Turning over a rental for the 1st time in 6 years - pet odor

[Megan Moody]

hi BP community - Happy new year! My husband I became accidental landlords 6+ years ago when we moved to a single family home and rented out the townhouse we had outgrown. We've been blessed to have no vacancy over the 6 years, steady rental income, however, we made the mistake (as many do) of not checking on the property and as a result the tenant must have acquired a cat that used multiple parts of the home as a litter box. 

Ughhh - we're replacing carpet and painting. Kilz has been a god-send for sealing in (or out, I  guess) pet urine odor on baseboards and subfloors under the carpet we removed (disgusting)...wondering if anyone else has proven remedies for getting pet odor out, particularly in stairwells (formerly carpeted). We've taken care of 90% of the odors with the steps I mentioned above but I still get a whiff every now and then and am hoping to get the property re-rented in the next 30 days.

Many thanks~

Megan
