Advice needed on 2 loan options

[Sandy Hu]

Hello,

I need advice on 2 loan options when buying a duplex in southern California ranging .9m-1.3m.

1. 10%-15% down with 30 year fix of 4.75% interest rate. It will require PMI
2. I put down 10%-15%, and Unison matches my downpayment, which will bring my total down payment to 20%-40%. Then I took a 30 year fix with 4.75% without PMI. For the money from Unison, I pay no interest and no monthly payment. However, they'll get a 20-30% cut of my net proceeds when selling the property.

Which loan option would you go and why?
