Look at the trend for tiny homes now.

So don't put it on a tiny second floor efficiency.

I agree with @James Wise, you don't want to compete like that.I've always been an advocate for quality over quantity and Redfin is purely the latter. 

Zillow will probably follow the same strategy since they have to think in terms of high quantities to make share holders any money.

The tiny structure built into a hillside in North San Diego or the tiny structure on stilts above a major freeway (163) may not get redeemed. 

I'd like to have a couple of 2-4plexes, 1-2 small homes to use as  Airbnb's near the Russian River area, an ADU in the backyard of the exiting house, land to create a Tiny Home Village and a new house for myself and my family. 

I imagine he is just willing to take the risk with the quantity of work he is doing, but at some point it will probably catch up with him..

I found out my basement has a leak and spent a few hours last night mopping with a tiny sponge mop.

My current thought is to put a tiny home or the like on the property and renting it.

And large quantities of street level retail in New York are now empty due to the pressures of Amazon.
