For now it's basically Google forms and self built websites. 

Each parcel can host up to two units, effectively enabling up to four units on what was previously a single-family lot.

I don't know how much more cost effective a one off modular  house will be.

What I would tell you is that as we built our portfolio we continued working our full time corporate (cubicle) jobs until we had 20 units (self-managing them along the way).

After a bit more research, I actually think renting a place will get me started faster and earn some experience doing Airbnb with a little less risk involved.Obviously I still need to be concerned about not violating a lease agreement by doing so and I would likely live on the property and lot or all the time.Ownership is still the ultimate goal, but this looks a faster party to self driven income.

A good attorney will even warn you if you are doing something illegal.As you can see from the list, a wannabe or "self taught" or poorly trained by videos or in a "community", does not provide the breadth of knowledge & experience to keep people out of trouble. 

Over time you’ll see a lot of people say the same names and you end up with a self-confirming list of recommendations. 

@Peter Mckernan Love the way you did that deal and agree that those deals exist both on market and off market you just have to be able to look for them in an effective way and add creativity. 

This alone was most effective.

The alternative is to set up a self-directed IRA, or better, a truly self-directed Solo 401k plan, invest in alternative assets, and then do the conversion.
