It does not take much to give off odor.I had a unit that had a wet dog smell, I did a complete remodel and still had the odor I found a big hair ball under the fridge.Paint the subfloor with KilzCaulk trim (hair can get between wall and baseboard)Vacuum registers and cold air return ducts and change filterOpen windows for a few days can helpPaint or wash all surfacesIf unit has been vacant drain traps may be empty allowing sewer gas backup

I focus on internet resistant tenants (gyms, karate schools, restaurants, nail salon, barber shop or hair salon, off site dry cleaners, doctors office,etc).Online sales makes up only a fraction of all retail sales.

Quote from @Muriel Hair: Has anyone use SimpliyEM for property management software, If yes, please provide pros and cons. 

Come with your friends who are not moving in with you with baggy pants and dyed hair?

Perhaps we prefer to live in a state where it doesn't feel like you're walking into a hair dryer 6 months of the year. 

I'm trying to decide on how the cost & profits should be split between partners after I have already invested so much in the first year +  I am the creater & operator of my natural hair braiding and dreadlock salon.

Anyways look at these assets and we can talkMain Home houston $1.3M value                       Mortgage $200k2nd Home in florida $650k value                        Mortgage $228k  $3500/mo rentRental Home 1 - $65k value                                Rent - $800Rental Home 2 - $65k value                                Rent -  $850Rental Home 3 - $65k Value                                Rent - $950Rental Home 4 - $65k Value                                 Rent - $950Rental Home 5 - $65k Value                                 Rent - $50027,000 sq ft lot - $150k Value                               Rent - $80037,000 sq ft lot - $150k Value                               Rent- $400(small 400 sq ft hair salon)Also have 1 car note for $70k, car worth $200k$2.575M in real estate $500k in debts(counting car)Anyways my issue is, small business owner, been in business 30 years I lease it,so nothing on my balance sheet land wise, lots of cash from business, business returns, we did $5M in sales last year, my personal income isn't enormous bc of writeoffs + cash but great credit and credit history, no issues.My issues are 1) I added 2 of those rental homes this week actually, but they're leased out2) all those rentals pay me cash3) debt to income was too tight last year for 2nd home so I put half down on it, son lives in it pays $3500/mo....maintenance $700/mo, taxes $700/mo + $1270/mo mortgage + rest goes towards principal.

And while I'm admiting to be a carefree lawbreaker, the lady that cut my hair a few weeks ago was - get this - UNLICENSED!

Your friend got away with moving people in only because the prior occupants were ignorant, and didn't know they likely could have the new owner by the short hairs.  

Other than that they are short haired, not aggressive and being 20lbs and blind not going to be much of a problem except maybe accidents.
