I just created an income producing asset creating $600/month in positive cash flow with none of my own cash invested.  

Fortunately the appreciation has produced outstanding overall returns.  

I know this has been spoken about before but I am currently working on building tiny home developments, like multifamilies using tiny homes throughout the country and was wondering if anybody else is doing the same or has interest.

Looking for someone with information about tiny home living and if it’s possible to create a “recreation vehicle” type of arrangement for tiny homes.

To your second part of the question: Most multifamily will be tenant occupied, which means they are producing income.

Can you offer tips that aren’t going to produce properties that are on every list imaginable?

As you mentioned its a tiny bit more complicated, and there is a question of change of ownership if your currently holding the property in your name.

It's not often that a low producing property recovers that much.  

One theory is that the investors see population increasing in these areas and are willing to deal with the ridiculous local laws This actually isn’t even necessary true, the placest with the biggest per capita housing production or “investment” is in the sunbelt, the expensive cities produce a shockingly low amount of housing, obviously zoning laws play a huge role in that as well, but even when you looking up institutional investment in existing properties it’s mostly in the sunbelt, most people who own big buildings in hcol areas just bought them decades ago when they were much cheaper, even D.C. has has like a 4-5 fold increase in value in some areas in the last 15 or so years.

I've considered doing Tiny Houses for the same reason.
