Investing $400,000 (as two $200k down payments for eight units with 50% LTV) in forplex properties is predicted to generate cash-on-cash returns similar to private money lending (10-12%) by the time the investor reaches retirement age (around 65), in addition to equity growth and tax benefits.
"take 200 grand and buy a forplex, put 50% down twice, you know, so buy eight units, 50% LTV... if you're in your 50s and you're trying to set yourself up for a 65 retirement, by that point, it will probably be generating the same kind of cash on cash return [as private money lending, 10-12%]."
