Realtor investing on the same property I am buying, is that allowed?

[Luis Renteria]

So my buyers are short 5% on a non-owner occupied 4 unit property in San Jose we need to be at 75% ltv and currently only have 80%.  the realtor on the transaction is willing to buy into the property 5%.  I am wondering if that is allowed being that the Realtor is representing the buyer on this same transaction.  Any thoughts on this?
