There're a million ways to make a quick buck in America, one of which is by breeding two deer who are also very fast. But since that ironically takes quite a while (200-day gestation period!), another one’s renting out every free square inch of your pad and/or driveway via Storably, a project led by a Wharton grad who also studied at Texas and previously ran a drugstore chain -- so clearly dude knows how to hook 'em.
Just list how much room for other people’s junk/cars you have available (total auto/motorcycle spots; room for everything from "a few boxes" to "furniture"), checking off applicable amenities (e.g., climate control, surveillance...) and access times before setting a price and uploading a photo, which should really be of the space, regardless of how well your recent glamour shoot at Sears went.
They even provide guidelines on what a good asking price is, and you can use the built-in Dashboard to track your spaces, send out rent invoices, and touch base with your renters, though do keep in mind that messages like "Thanks for the car, loser!" won't inspire much confidence in your customer, even if it will net you a sweet LeBaron.
Should you need some extra room yourself now that your house is completely full of strangers' stuff, Storably's got a search bar and map that'll comb nearby 'hoods, letting you find the perfect spot to store all the deer you're using as Johns.
