Coffee shop(1200sqft -- Rent 1050/month on a month to month-- been here 3 years), laundromat(2800 sqft-- rent 2050/month with 6 year lease-- rent increases by 225 next year and in 4 years-- been here 5 years), and hair salon(800 sqft-- $850/month on a month to month-- been here 15 years).

When we bought a property the sellers were not motivated until 2 to 3 days before they were going to lose it.. then it was hair on fire to get them done... and you needed CASH the wholesaler bit simply was a non starter.. irrespective of tying up a property when you have no money hoping to wholesale it.. think about your grandmother.. would you like someone doing this and risking them losing their home when someone who has cash could actually help them. 

Some ideas for that, insurance agent, tax preparer, hair dresser, bridal shop, massage, tattoo.

it was hair on fire getting it done.. but you talk about motivated sellers... 

Running a hair salon in the unused part of the house.8.

If I didn't shave my head I would be pulling my hair out.

HOWEVER, I had to take the building with a tenant who started an illegal hair Solon.

The commercial unit is occupied by a hair salon and it needs work, but it’s on a main road in the suburbs and seems to get plenty of business, so I like that it’s already commercially zoned and operating.I work in commercial loan servicing, so I’d get a reduction on the closing costs.

The previous owner had a daughter that regularly dyed her hair red so the tub was stained red.
