How can I help landlords/agents/investors

[Brett Bourg]

Hey guys, I’m a door-to-door salesman selling Tv, internet, and home security, And In my Turf I have about 9000 addresses, and knock about 100 doors a day. My area has quite alot of people moving in and out.  

My question is How can I help/work with landlords for them to refer their tenants to me?
 
I want to help from a value standpoint. Whether it be giving them contacts of people I meet that are looking to sell their home or abandon houses, etc. 

How would you want help that would be valuable to you? 

Any advice appreciated.  Thanks.
