Unit has brand new Berber carpet from previous owner but am thinking of installing either hard wood, engineered wood or porcelain tile.Anyone have a good floor installer or contractor who could do the work? 

I have never had to evict a tenant that I screened (knock on wood).

If you have a choice, choose someplace where the economic trends are starting to look good, on the definite upswing, and build your base there.From what I see of RI and the Northeast, that isn't yet happening up in this neck of the woods and I don't see signs of that starting to change at all.

Hey @Ross Woods welcome to BiggerPockets!

@Kevin Wood one of the key factors is where your rental is in the country in respect to climate.  

Obviously if I want to push the higher comps I'd do something like refinish the bath and put in hard wood floors on the main level.

Bleach will work on hard non-porous surfaces but wood, drywall, ect it does very little and in fact can make the issue worse.

The place needs carpet, paint, skylight leak fixed, wood floors refinished, and bunch of other minor stuff.

I really don't want to spray it off cause that would require a second story ladder and the paint/wood is well rotten all over the outside and is liable to fly right off.
