There is a web site that lists all the section 8 housing, so people might be also be looking there. 

I plan to leave them enough that they can afford to buy a house or start a nest egg, but I am not leaving large sums to them.

And how do you approach balancing asset management between third parties and in-house?

(No whole house rentals.)

That is a great place to start, as well as hitting some local real estate investor meetups so you can meet some other house hackers in person who have done what you want to do.

Also, what niche jobs in real estate (Agents, appraisers, house inspectors, lendors, ect.) are going to be replaced eventually?

. :)Anyway, I like your strategy of driving and looking for houses in need of repair and sending handwritten letters and contacting rentals for the reasons you gave.

This influx of workers will naturally drive demand for housing, retail, and other services in the surrounding areas, especially in smaller towns and cities that haven't seen major growth in decades.

Starting locally with multifamily and house flipping is a solid plan.

I have land with a house and plan to build a a house for me to live in soon there.
