Buying multifamily new or used?

[Leeann McGee]

Hi.  I'm new to the investing world and any advice from investors is appreciated.

I have an opportunity to 1031 exchange into a new multifamily unit, construction to begin summer 2020.  There will be no cash flow for a year.   

My questions are:  Is this something a new investor should delve into, new construction with no cash flow for a year?  

The pro forma on the fourplex suggests $600/month cash flow when it is fully leased in a year (or possibly longer).  Does this sound like a good return?

Would it be better to 1031 exchange into multiple turnkey single family homes that are already established and can cash flow within a month to two months?

I'm looking for multifamily, but I guess I'm unsure if new construction is the way to go.  It sounds like a good idea because there will be little to no maintenance for a while since everything will be new. (The new construction multifamily investment will max our 1031 monies.)  It just seems like putting "all my eggs in one basket" and waiting a year to earn cash flow will delay my investment opportunities and journey.  

Thank you for your advice.
