Make the rules such that the tenant, in order to get the extra federal unemployment, must pay at least half of it to rent.

Often folks don't sell all of the royalty or production but a fractional amount of it. 

As @JonathanGreene said, tech has created an environment that allows folks like you Jon, to enjoy investing on your terms so that you do not put all of your eggs into one basket (so-to-speak).

The biggest difference is having the patience to wait until what feels like the last minute to book folks compared to LTRs.

I would rent out an extra room, basement and yep, deal with a part time roommate.

Purchase price: $82,077 Cash invested: $50,000 Sale price: $275,000 Fix & Flip mobile home with extra lot.

I also agree that RE appreciation is unlikely to match the last dozen years, but you never know.Where I am unsure we agree is that paying $450k to improve the cash flow ~$3k (your numbers but I expect my delta wold be similar meaning both my cash flow estimates would be worse than yours but both would be worse by the same amount not affecting the difference) makes sense especially if the cost of having the extra $450k is only 6% rate which is historically simple to beat via numerous investment options and hopefully no one is investing in RE for an expected of 6%.  

And all of this happens during the contract period reducing purchasing risk.Great strategy especially when practiced just on the outskirts of a major metro area in a country setting(a weekend getaway property that can be marketed to city folk).  

I usually advise folks moving to a new area to rent for awhile to get the lay of the land.

For example, this can be adding square footage, adding an extra unit, or adding a pool in a STR market/luxury market.
