Since staying home indefinitely is the new norm people want a nice suburban home with elbow room.

Yes I think we will disagree (in my case) as the time remaining for compounding for me is realatively short and my rate of tax paid after I stop working will likely be significantly lower since what causes my rates to be high currently is limited to employment income, the rest of my income although considerable will nearly all be indefinitely deferred the way I invest and likely will remain so through retirement until death. 

If you use a personal car, make sure to keep a detailed record so that CPA can prorate the expenses between personal and business.

As far as I know, the section 8 is indefinitely.

SSI disability income can continue indefinitely. 

Doing this you get to indefinitely defer paying the tax on the gain from the sale.

@Lin Ding you mentioned that you plan to refi in the future...the problem is, nobody knows when (or if) rates will go down (and in fact, they might be elevated for a long time).  ...the last time we had inflation this bad (late 70s/early 80s), rates rose and didn't come back down for a fairly long time (years)  --here's a graph of mortgage rates going back to the 70s:  https://fred.stlouisfed.org/se...I think all buyers these days need to be able to live with the property indefinitely at the rate they're buying it at right now. ...If a property doesn't pencil out at the rate it's being bought at, then it probably doesn't pencil out, period.

They use conservative leverage on every deal, put high skin in the game and offer a 1031 exchange program to defer taxes indefinitely.

Plan is to keep the properties indefinitely.
