Should I build? or Buy?

[Rhett Stephen Lowe]

Hello everyone, I have been stuck trying to figure out which route to start my real estate investing. My fiance and I currently live in my parents basement so we have little expenses. We are getting married august 15th 2020 and my parents are gifting me 2.5 acres in Howell Michigan. I have been drawing blueprints for our house that we will be building, we will only be subcontracting a few things out like the foundation and septic field. We will be doing everything else our self's. My plan is to fund the build with greenstone's D.I.Y loan then after the build get it appraised and do a Cash-out refinance so we have some money to buy a Duplex or single family house. 

or..

Hang onto the land and purchase a duplex live in one side rent the other..

Thank you!
