I play baseball here and the student population is growing rapidly.

Replaced flooring, remodeled the back yard (it was a mess), upgraded fixtures, and paint.

Hi,We have a house with a large back yard.

I wouldn’t self manage the property even in my own backyard.

Garage has open live wiring exposed suggested to install, small Shop in back yard roof sheathing has Water damage, missing smoke detectors/carbon monoxide detectors in the rooms, no A GFCI Outlets in Bathroom..

They can bury that in their backyard.  

You should be able to figure out what your particular market covets (more bedrooms vs larger open space; backyard vs front yard; etc).

I'm looking into importing prefab / modular houses from China to be used here in California as backyard homes / ADUs.  

@Andrew Erickson Right now the ADU rules are being relaxed all over California in order to help solve the lack of housing crisis. there are a number of contractors who are specializing in helping home owners put small units in their back yards.

One where an owner came out with no shirt and a baseball bat, pissed as Hell and ready to go with a violent fight over someone even asking about buying his house (which he was very close to losing)..Another one where the residents being foreclosed on took off with; every single cabinet, appliances, all plumbing fixtures, light fixtures, HVAC systems, water heater, smashed the drywall to rip out all the copper wiring, took the breaker box, took out every interior door, ripped out all or the laminate flooring, stole the garage doors and motors, even dug out a bunch of plants and trees from the yard!
