Sometimes they brush off the conversation whenever I bring it up.

Be sure to brush up on the "prohibited transactions" so you're aware of what isn't allowed.

The realtor would likely brush you aside, however, in the best case scenario, the investor you bring to the table would have to pay you a finder's fee, not a commission from the realtor since you are not a licensed agent.

He seemed to brush me off because I'm not a cash buyer.

I am thinking about providing new tenants with a welcome basket of basic cleaning supplies and household items like: paper towels, toilet paper, toilet brush, plunger, dish soap, and all purpose cleaner.    

Thank you all for your advice and answers to my novice questions and for not brushing me off.

I have properties in Brush Park and North End.  

I provide information forms to all new renters giving them the pertinents - location of water/gas/electric shut off, phone numbers to all utilities and emergencies, trash & brush collection info, specific information about maintaining/cleaning the house, etc. 2.

Fort Morgan and Brush to be exact.

You are always going to get some crappy agent that is going to complain because they are scared of loosing business but just brush it off.
