Broker Etiquette - Off Market Leads

[Mitchell Dyer]

My goal is to add value to at least 100 units by the end of the year and I got my hands on a list of ~3000 off market properties in Houston, TX (Harris County), about 20% of which are 100 - 300 units.

Would it be proper broker etiquette to share this list of off market addresses and ask for the broker to focus on properties between 100 - 300 units to determine which properties are ready to sell? If possible, the broker could represent the buyer and seller.
