I have a 5 bedroom 3500 square foot home in South Charlotte.

If you get to the point where you start removing walls, your contractor or lumber yard can provide the sketch and structural calculations for permits.Paint and carpet = cheap and high ROIChanging footprint = very expensive, often negative ROII would avoid it like the plague.

For example, if there a small back patio with the roof line hanging over the patio and you do not need to add/extend the roof that is a great move due to the high costs for adding a bigger footprint to the roof while adding the framing etc for more sqft.

Quote from @Ezekiel Trevino: I have heard about 3D printed homes.

I have a potential partner looking to convert a motel in studio apartments. Question being, is there ANY LEGAL REQUIREMENT or Minimum square footage or area needed in order to rent that studio to section 8? Does that ...

Investors can find riverfront or water view properties with solid bones or a smaller footprint that is upgraded.Bonus HOT areas with variety of budget points: Seaside - Quintessential coastal community within striking distance of Portland. 

Basements that are the same foot print to be able to add a second dwelling for more income in the future, and being close enough to the 20 & 285 for commuting.

My dad decided to self gen his leads.. much like you wholesalers self gen leads today.he bought a printing press I printed off door hangers after school and then my mom drove us to neighborhoods and we physically handed out the flyers door to door. 

It can be done more cost-effectively if you can do it within the footprint of the existing foundation and just build up, but still negative ROI.Probably better to move, rent your old home and buy a bigger one.

The majority of our investors seeking larger complex footprints usually explore and invest along the I-5 corridor south of Portland to the California border.
