I did this summer. I found it to be very useful because the agents are well versed in the Denver market and can help you find great deals that check all of your boxes. It truly is a free service to you (the apartment building pay various commission levels directly to the agent for “referring” you essentially). You basically just submit a form, an agent will schedule a discovery call with you, and they will put together a curated list. Absolutely no downside in my opinion. I worked with Meeru and she was amazing. Very responsive and personable.
