Agreed that it's the best neighborhood in the city!

That's because the city won't calculate the actual amount till a structure is built, aka it's not just a plot of land anymore.This will obvious cause your property tax bill to go up and also your mortgage escrow account as well (sometimes these things can make your mortgage shoot up a few hundred a month). 

He also doesn't control regulations in the states/cities, but his attempts to cut regulations may trickle down and impact personal property rights and people's ability to use their properties as they see fit.

Couple hundred bucks a door monthly cash flow, solid ROI, and yes plenty appreciation (#1 appreciating city 2023).

As you move to the next team/city you can repeat the process. 

While the property is in a smaller town, it’s relatively close to a larger city, which I think adds a lot of potential for attracting both short-term guests and long-term tenants.The motel has fewer than 16 rooms, and the nightly rates are extremely competitive for the area.

From what I've heard, CA is very ADU friendly so check with your city on what's allowed.

Call your city and see if that's large enough, I think you need more like 10-12 ft width and 15 - 20 ft length.

You need a siteplan that you can present to the city.
