I'm not sure where the $2,866 comes from. In my example the property was paid off, but to finance it, you would lose the spread (mortgage rate minus the cap rate) on whatever you borrowed. Rent is $1750 a month and expenses are about $500-$550 a month, which includes the condo fee, which covers most of the long-term maintenance, and all taxes and insurance. So that's net of $1200-$1250 a month. Taxes are low here (~ 1%), which helps.
It didn't make sense from a cash flow perspective to buy when I did (because rents were 20% lower) nor does it make sense to buy from that perspective now (because prices are inflated). My point was just that if rents stay where they are, and prices slide 20%, then it starts to make sense to buy rentals.
