They only problems that I can think of is that the washing machine and dryer are in the kitchen, which was the style back then in these types of houses.

Or put in a Hepa filter machine in there for a few days and see if that can get rid of it? 

But in the right spot as I said its a awesome cash cow machine.

.  Wash all machine-washable bedding, drapes and clothing etc. on the hottest water temperature and dry on the highest heat setting.

I decided to get an air purifier w/HEPA filter to stay in the 4 br house and an ozone machine to use initially to get rid of the stubborn smell.

There are some great opportunities out there but there are also some cautions you need to have, not everything has the occupancy and the high ADRs that we saw a couple of years ago, there are still some money-making machines but you need to invest in something that's not a commodity and make sure your investment really stands out from the competition, there are more units coming into the market in the next couple of years.

I will run an ozone machine in there if they move out.  

I had my real estate license so I have some level of understanding of the process, but my full-time job has consumed my time so I've focusing on that instead.For background on the property:*15-year old townhome*3 bedroom/2.5 bath*Unfinished walkout basement*Trex Deck*Good schoolsTo prepare to rent I've replaced all 3 toilets with brand new units, new sump pump, new garbage disposal, new modern kitchen faucet, and new washing machine water lines.

It'd be great if you left thoughts there - i'm trying to get more replies - so that more people leave their replies too.https://www.biggerpockets.com/forums/311/topics/67...From L to R - My wife, Judy, Parker Jr (PJ), myself, and Kyle - in Horseshoe Slot Canyon, AZ, in July 2018
