Go with what you feel comfortable with.4.

@Aaron Zimmerman and clarify, I am the marketer, my husband designs lighting.

I’ve been around real estate for decades, and I read in The Economist once that in lively markets like Charlotte, folks will pay a premium for a comfortable room if you’re near major employers.A friend of mine tried something similar out in Austin a while back.. he’d inherited a 4-bedroom property and split it into individual room rentals.

This designation doesn’t cost extra or give the manager access to insurance payouts but ensures you and the property manager are aligned during incidents, such as tenant lawsuits or insurance claims.

Also make sure you are comfortable with some holding costs if the units don't get rented right away (if vacant).Also look into if there is rent control in the area that the property is located.

The new design takes the home from a 3 bed, 2 bath to a 4 bed, 3 bath, 2,400 sq ft rambler on a large lot in highly desired area.

We jointly designed the house to their specs.

It all really depends on what your buy box is and what your comfort level is. 

Also you could start with local Plan-printing companies as they're always printing plan sets for architects and designers before they go to county and after the county comes back with changes.

For bookkeeping purposes, I recommend designating a separate bank account exclusive to the house hack activities to keep some sanity.
