I went so far as to join the local realtor board as an associate member.
I am allowed to search their MLS.
I began sending out emails, "Congratulations on you sale", "Good luck with your open house", "Here's wishing you a quick sale for your new listing".
Each email also talked about our handyman division.
Four or five realtors responded positively, no leads though.
Two realtors called me and blessed me out for bothering them!
One of them was a realtor that sends me unsolicited mail almost weekly including a tacky, boiler plate newsletter!
