To students, on Airbnb, rent a couch, a closet, the backyard for camping, whatever.

Only one bath in the house, so I'm not sure I want to cheat it, but the br is tiny and currently has no closet.

Portable heat pumps are another easy option for inexpensive supplemental heat.

It's area specific sometimes based on the taste but here in California my top 3 would be master bedroom with walk in closet, kitchen, and then yard if applicable.

Someday someone can research the bizarre relationship tenants have with window screens and closet doors.
