We had a similar problem when we inherited heavy smokers & 2 large caged dogs. 

Can you not accomplish the same thing with a tapestry or grill, and some words in a lease?

I am trying to make a decision on what to replace the carpet with, damaged due to heavy smokers. 

Part of what I factored in is new appliances including w&d in each unit and there is a nice yard that I’d like to make an amenity by adding a small coal fire pit and grilling station.Do you think there are amenities that would add value to get it to higher rents?

House had a terrible smoker and cat lady which made it a complete gut job.

Non-smokers only.

Amenities such as a 24-hour Fitness Center, Sparkling Swimming Pool with a sundeck, outdoor grilling area, plus a whole lot more.

STRs only recently got a bad rap because of excessive use of police resources (kicking out smokers, parties, etc.) and now require fees and a license. - Back to your 2-3-4 unit dilemma.

Since this topic is more focused on a specific area I'm more than happy to take the people who provide the most insight (imo) out to lunch/dinner (Capital Grille, Eddy V's, Morton's Steakhouse).Thanks to everyone that has read to this point.
