If you have space, you rent out office space for meeting, have mailbox services, rent land to cell towers, etc.. if you have right of ways or easements that you can't build on, you can place portable units or have parking for boats/RV/vehicles.

Portable loans = When you sell a home, most generally buy a new home.

I broke down last summer and finally got a portable unit after living in Oregon for 11 years without it, mostly because I was worried about my animals when I was at work. 

For instance, if you wanted to email someone a PDF link for a value write-up in a pinch.Also, if you are on a Mac, invest in a portable hard drive.  

My long term tenants are OK with portable heaters that I provided them.  

I intend to buy a house this summer and portably about 1-2 per year for myself and family after that but am open to growing into more deals as a side hustle.

I couldn't find anything this high for a more than a month so this one seem to be a good one.About the no kitchen unit, it was built next to the garage, image belowI don't know if it was legally build or not, but i was thinking of attaching a portable cooking station outside the house.

It's a valid point and strict camping isn't our focus, more glamping w/ amenities that include wood fired tub/sauna, decks w/ views, etc.

., plantation shutters, 3 car garage, 3 story elevator, built-in sauna, 2000 sq ft great room, gas generator, and much more).

It would be fun to see what game room does, or sauna, or garage.
