So it's great I got to free up the extra cash but now I have a property in which it's not cash flowing or not nearly as much and I'm supposed to keep doing this?

., if you're in the 30% tax bracket, you cut your earnings by 30% to account for taxes, or if you simply leave as is since you'll likely have most of your income eaten up, on paper, by depreciation and expenses?

On two of my houses I cash out refinanced them and they still flow positive albeit only a few hundred a month, but I got out all my money invested in those houses and a few thousand extra on top.

If they have plenty of money in the bank (enough to cover several months of rent), and good records on paying their rent (always check rental history), again ask for extra security deposit.

To earn 1M per year with let’s say a combined return of 8 percent requires principle of 12.5 M.

People who actually do succeed with sandwich leases and such like are not people who need to make extra money at seminars from people who have no savings and not much income.

Think about a full time doctor, tons of money and zero extra time. 

If you believe you need the extra level of  psychological protection spend the extra money and sleep better at night. 

On the surface, getting an extra 2brs for $20k seems like a winner.  

The positive note here is I have enough income coming in from it to at least cover my fixed costs and have extra for anything that pops up if I were to have 3 vacant units until mid January to March/April.
