Best Way To Find Active Mixed-Use & MF Developers In Your City?

[Curt Barbour]

My experience is in SF and small MF. 

Now, with a corner residential lot under contract in a mixed-use corridor zone in Austin, Tx, I seek guidance on where best to source my buyers for this smaller 7500+sqft lot which is zoned to accommodate up to 7 condo units, mixed-use, commercial, retail, restaurant, professional offices and even affordable housing.

Is it best I get in front of commercial brokers who may have developer clients? I've had limited success finding specific groups on social media to solicit this killer deal in one of Austin's TOD-Transit Oriented Development zones.  I've googled and reached-out to some developers with general specifics of this this property and have had a dismal response rate thus far.. 

All that to say... where do they hang-out online?  Is there a BP-like site for developers? Or, since I don't come to BP enough, as I should...are they right here under my nose?
