Hi all,I'd like to get some advice on the following.I own a couple of properties in central California with potential for building up additional units on each one of them.The first one is a tiny single family home (~800 sf) on a big R3 lot where I can get a permit to build 2 or 3 additional units (although the cost of the permit per unit is much higher if I build 3 or more units, so I might stick with 2)The second one is a duplex, 2 1-bed small homes on a big R2 lot where I can build at least 1 more unit. 

I just did it to get thoughts out and create a presence. and yet, I am astounded by how much money it's made me in a year for a tiny investment.

As a new investor, there are too many tiny details books can't teach you.

Ridiculous.....In the vast majority of cases that interest is going to be tiny and not worth the hassle of maintaining the separate account.

Though there are those who choose prefab for aesthetics and ease (such as the Sonoma weeHouse videos who stated they didn't have to "babysit" the build)........I recently interviewed someone who has a tiny house in his backyard and wants to rebuild the stick-built home currently on the property (it's tiny and needs repairs).

Even tiny, run-down 2/1 houses are well over $200K. 

@Leo Poon following as well - I've been thinking about this very concept with tiny houses and a gathering house, this concept will be fabulous and best of luck!

A tiny cat can ruin carpet as fast as a 150lb. mastiff can ruin landscaping. 

Marriott has a chain of 7 new "feature" hotels in the world targeting Millennials providing social environments on the main level and tiny hotel rooms.

In the mean time C-, D neighborhoods homes sold several M dollars a pop for 4 plex, 1++ M for old tiny SFH that one can not get much more than 1K to section 8 tenants today.
