Breakeven cashflow inv property, how should I think about return?

[Dennis N.]

Guys, I need some help in thinking through this scenario:

A property that has breakeven cash flow with appreciation in line with average inflation and minimal expense over 30 years. Lets say it cost 500k and I put down 100k of downpayment. Then wouldn't it still be a good deal since you are having the tenant pay for your mortgage and help you build up 400k wealth over 30years? Or am I not thinking this correctly? Or should I take the opportunity cost of not able to invest that 100k over 30 years?

Thanks! appreciate any insight here.
