I’m not adding any new electrical work or new plumbing.

I dont know much about electric cars.  

Good tenants do not want to go to the laundromat.Parking - Some tenants have nice cars and do not want to park on the street.Split utilities - Having the tenant responsible for electricity and heat is extremely important so you can keep your costs in check. 

What has bugged me the most are her constant phone calls about noise.

These units are distressed and will need lvp, paint, drywall repairs, electric and plumbing work plus fixtures, windows and HVAC.

That way each time there is a turn they bring a fresh set and take the used set with them to wash and use on the next turn.If your housekeepers are taking laundry home, you’re inviting bed bugs. 

What about the electric wiring?

To demonstrate my technical competence, for my personal house I built a steam shower, installed radiant barriers with rock wool, and a wood stove insert with bathroom radiant heated floors and re-designed radiant floor heat zones, cutting winter energy consumption to 1/8, installed a whole house fan cutting summer energy to 1/2, extensive localized landscaping leading to a reduction to 1/8 the yard work, plus random quality of life improvements like wifi switches, heated floors and toilet seats, skylight install, exposed structural beams, and master bedroom laundry including electrical and plumbing, cathedral ceilings with skylights, a steam shower with wifi controllable lighting and music, concrete countertops, etc. 

Most electrical and plumbing companies here are 24/7 just in case you have an emergency.

We have some major electrical work to upgrade (old knob and tube, spilt units to their own meter, ect) and would like to add in baseboard heating/ductless ac units.
