You would have to take out the half bath and laundry room or scale down the master to make room to add a kitchen for the back unit.

Some manufacturers started to build the walls with 16in on center just like site built homes which also made for better structure.

I sign a a letter stating that I will pay them a certain amount of money per lead that actually creates a transaction, I'm sliding scale, starting at X dollars.This is all free marketing for lease to own and lease purchase.You can buy leads at listsource.com or go through @Michael Quarles  @ yellowletters.com`````````````````````````````````````````````````Whatever you do be a problem solver and don't be a one trick pony, don't just be a wholesaler.

I now work as a regional training manager for the largest roofing manufacturer in North America.
