Rehabbing vs Building a Property Profit Margins

[Alex Ng]

How much are profit margins say if I build a 4plex vs just finding a distressed 4 plex and fixing it up? I expect constructing a new one to cost more and take more time to do, but does it have more profitability than rehabbing? Is it worth the time and effort to construct a new property vs just rehabbing an old one? I'm looking to get into contracting so I desire to flip and develop houses. Just wanted to know if it was worth it. Thanks!
