Take a look at the study from Amsterdam. by Piet Eichholtz Eichholtz_A-long-run-house-price-index.pdf (maastrichtrealestate.com)basically a nearly 400 year study of the prices of the same homes along the best canals in Amsterdam since 1628, and the prices rose at about 2-3% or the historic rate of inflation there, same study has been retroactively and proactively studied in almost all countries on Earth and they all get same answers over long term, (Re rises with inflation rate) Now you can have short term bubbles like now in USA, but they usually deflate like the 22% drop from 1929-1935 or the 34% drop from 2006 to 2012, which many of us benefitted from.

Most of the research I’ve seen is finding single family homes to renovate and lease to section 8, not multi family units. 

I’m considering options like building a single-family home for STR or creating a small RV park with a few pads, but I'm open to other ideas.

The property is located in an area with 1M dollar homes, but a single parcel (not in a neighborhood) and propane

If you can, go several times, so you can watch it happen from the foundation all the way up.If you live close to a store like Home Depot or Lowe's, sometimes they have free classes on "how to install a ceiling fan" or "how to paint". 

For instance, a lot of our house-hacking clients in Denver or Colorado Springs want a home with a basement apartment.

The home needs about 10k worth of work. 

I have been saving money and I believe I have enough for 10-15% down on a small family home.

I am driving home from work and see the Subway sign which sounds good.  

The other pool of tenants: One is a couple relocating to area high income earnerOne is  interested in renting as a "personal care home for 4 residents"One roommates working in the area with the same company needing housing for next yearI just need some guidance.
