I think from what I've heard you mostly do one thing which is retain your own household and operate your assets mostly as a landlord which brings in income and has various tax deductibles so you profit in that way. Also its a positive in that you will never be cursed with too much cash at any time that has to be managed, just the property itself. Stick to what you know is the most basic advice possible, most people know their own community and town, what land might expand in value or not and various sources of demand in land use I guess is not so complicated but to an outside party this might be far harder to figure out then someone who has lived in that town their whole lives. He says alot of other things but imo its mostly about invest or involve yourself in what you know, what you love and can handle the details of and most can manage the various jobs on housing or sourcing the people who will do that job etc.
I thought that is the only way to get out of this matrix hell, but there is always counterparty who would do everything they could to invade your private space. I call this bully in life would always around you and find any possible way to ridicule you and make your life a living hell, I was once come across the mostly absurd accuse ever, the bully told me:
"you didn't verbally say I can't spend your money(to buy to my heart content!)", , which is full of political bullshit, little did I know monetary issues could soon become family affairs hell, and there is little to no justice left when thing come to this point, bully can bend the rule just to do all the outlaws thing whatever he want, and the weak cant do anything practically from suffering monetary loss, in the end survival of fittest, strong bully the weak always take over the entire society order, not about fairness, not about making your hard earned money,
