@Aaron Xie as stated above broad question without any other details.  

It is very important to learn about this in a broad sense...as they say, ignorance of the law is NOT a defense!

The difference is you do not know just what you might need in the future so best to build the network broadly and in advance.

Here is the catch...if you find any sort of single family detached within your contract period you owe them a commission (the one that you signed for a SFD, not commercial).Also, what you could do is instead of write SFD (which is broad), write something like "SFD in Anycity".

I have very little faith in the 4% rule, because a misspent youth taught me again and again and again that dice have no memory and I see more and more people investing in broad-based index funds every year.One of the few truths I know about the stock market is that when investment is concentrated in a specific sector of the market, manipulating that sector becomes a very profitable endeavor.So what would it take to manipulate the value of VTSAX holdings?

Basically, in the context of FI and your broader portfolio, should you think of income properties just like any other asset with their own ROI (no different than a stock or bond), or should the expected income from these just be deduced from what you expect to spend, and you really ignore the equity portion of it.I think this more broadly speaks to the question of how to transition from growth to income and how to plan for that as you build out your real estate AND stock/bond portfolio.Any thoughts/advice appreciated! 

I know this are rather broad questions, but I want to learn the market from other locals with experience.

Obviously we can't predict the future with any real accuracy, so who knows what the broad market will think about ADUs 30 years from now, but in my market even though they are uncommon, they spike the value of homes anytime they are well kept. 

In the kitchen we provide an array of spices, some other basics like olive oil / vegetable oil, a few bottles of water in the fridge. 

The best answer requires a deeper dive, but broadly speaking most mobile home park investors want to own the land and not own the units.
