No reason not to throw the kitchen sink at it.

Obviously, stuff like; paint, new flooring, new kitchen cabinets, etc. 

The idea is to split the huge kitchen in the big house and divide the house into a 1/1 and a 2/1 and slip the additional unit in the unused attic.

I’m now pacing on my back deck, this guy is off his rocker.Now I’d been in the attic recently to replace some pot lights over the kitchen, maybe I stepped on one of the lines?

Renovating kitchen is lot costlier than a smaller kitchen in a duplex/quadplex.Are they all scattered over the country or do you cluster them over smaller area/cities?  

New siding, added central air, rebuilt deck, updated bathroom, kitchen, and flooring Lessons learned?

kitchen cabinets Cheep and goodThanks.......

All new electrical, plumbing, flooring, kitchen, bathroom, walls.

(New cabinets, new appliances, redesigned kitchen layout, refinished hardwood floors, some drywall replacement, all new paint, etc.)
