10 single houses vs A 10-unit building

[Quy Huynh]

I've been torn between the follow decision. A 10-unit building financed making 10% cash on cash annually VS 10 single houses paid for in cash making 18% cash on cash annually I want to obviously go the 18% route but if ask myself why do I go this route when all the big players buy bigger buildings? Am I maybe trading risk for return? What have you guys done or experienced?
