Reselling stuff on Craigslist/eBay/Amazon works great, as would renting out a spare bedroom in your duplex unit on AirBnB, and doing freelance work on Elance or Taskrabbit.

@Nancy Bachety it's easy in the sense because I do a trial and error period and try out multiple cleaning companies which I source via google/yelp/thumbstack until I find one suitable in terms of efficiency, cleanliness, adequate staff etc.Charge is based on size per home from studio up to your mansions and varies per the city you are in.

I currently am into restaurant franchising (Subways) after leaving my corporate job at Amazon, however, real estate has always been the long term goal.

I scrounged up everything I could find for furniture locally using the standard sources but everything else I ordered off Amazon including mattresses, sheets, etc.

Whereas on AirBnb, Yelp, Amazon, Uber etc anything from 4.5 and below is crap.

We (gf and I) rented a small 1 bed/bath with washer/dryer in Martinez, CA (east bay area, small blue collar community about 40ish minutes from SF) studio last year for $1850.

In the basement you probably have good sound proofing, you can also consider a recording studio that rents it by the hour....depending on the area of where it is to see if there are demands for any of these things.

We are half way through a full gut remodel and shift to the floor plan, changing the 4, studio units into 1/1's.
