But these tend to be tiny projects in the grand scheme of construction projects (probably sub $5 million for the entire project cost).

Check out tiny houses on pinterest for layout ideas.

Has anyone used tiny homes to add to multifamily properties where zoning allows?

Got the stove off Craigslist for $100, the fridge from a guy that does best buy liquidations for $620, the 18" tiny dishwasher that you can't see was $400 no deals to be had on the little guys.

While only a tiny percentage are interesting, you can analyse much more deals much faster and they are ready to go.

I just started building tiny homes in my hometown in Eastern Texas.

New Yorkers love to squeeze into these tiny, overpriced units and so obviously there will be 1-2yr turn around on new tenants.

Another great resource would be the Triangle apartment association www.triangleaptassn.org Another syndicator local to your area is https://www.prudentgrowth.com and @Paul Moore is full of knowledge and a tiny bit of humor occasionally lol.  

We do have a house in contract in SW which would be a perfect house to convert into a duplex and/or build a tiny home on it.

I have an opportunity to buy a tiny lot in a gentrifying neighborhood.
