Well working from home doesn't really give you a "place to go". Besides, if you do want to work from home you probably won't need that much starting capital.
Now if you want a place to go to get out of the house I would suggest the following. But be aware that these all greatly depend on real estate/rent in your area (office space) and your own skills/desires.
Dog rescue/training facility
Baby day care center
Laundromat
Buy a food truck (bagels, sandwiches, something ethnic)
Real estate office for freelance brokers
Storage facilities
Management office (real estate, accounting, office, international)
Travel agency (best in niche - islands, cruises, specific countries, etc)
Consignment shop (clothes, household items)
Dollar store (mad profits)
Take out cafe (standup tables only type of place)
Coffee importers
Home importers (best of country- oriented like India, Thailand/Burma, etc)
Mattress discount store
Electronics shop
Cellular shop
Dry cleaners
Pet groomers
To name a few. Have luck (and I want 2% consultants fee)!
