Also any other screening “rules” you would suggest.First was if they left the “do you smoke” question blank.

The cost is high to work with hardwood floors.And one tenant with cat or dog pee left setting on the floor will give you big dark stains or stains that run the edges of the wood. 

The house is located in blue collar neighborhood, the properties around our house have new (good looking) siding, but ours definitely in a bad shape, has dark color, was painted by previous owners.

A good smoke detector is more likely to save you, your family, or tenants' livesAll investors should nurture strong relationships with Realtors, lenders, title companies, etc. so you will have every alternative available to you if/when needed.

Also, check current smoke situation and code, there have been lots of mandated upgrades lately in our state and maybe the same there.

The inspection is not a big deal provided your property is being maintained.Typical things are peeling paint, inoperable windows, GFCI in the kitchen and bath no matter when it was built, handrails, smoke detectors, carbon monoxide detectors if applicable, etc.  

Its amazing how dark it is when the air is thick with smoke.

Isn't there also a dark side to month-to-month renters, in that they have a very low penalty for bailing out on you?

I’ll do a walkthrough, to replace filters, check smoke detectors, turn on/off outside water, etc every 6 months.

Unit B: Rent is 750, tenants keep good care of the place and are MtM, could still use some normal updating and minor value-adds.Unit C: Rent is 700, very elderly tenants have been around for 5+ years, are MtM and kept pretty good care of it sans the chain smoking and buds everywhere.
