Feel free to gut my investment plan :)

[James R.]

Hello all,

 I have owned a business for a while, but I am fairly new to multi family real-estate investing. I own a commercial office building with a fair amount of equity that I can leverage. My plan is to buy a already zoned lot for multi family and build a 4-plex on it. I am planning on being the subcontractor for this build as to help build equity in new units. ( I have never been a sub before, but have a fair amount of construction knowledge from previous renos)

Does anybody have any input on this plan? 

Thanks!
