Looking to hire a property management company to manage my duplex, which I have been managing since 2018.

It’s great for getting an idea of what similar properties are going for in your area.Zillow Rental Manager: Not only can you list and manage your rental property here, but it also offers rental price estimates based on local market data.AirDNA: While primarily focused on short-term rentals, AirDNA offers data that can help you set prices for medium-term rentals by providing insights into occupancy rates and revenue projections.PriceLabs: This dynamic pricing tool adjusts rental rates based on demand, seasonality, and local events.

I recently met with the owner of a property management company.

If you struggle with creating a strong agreement and enforcing it, then you may be better off hiring a property manager.

@Adam SchneiderRecommend exploring as many sources as possible to get referrals AND cross-reference them to get as much accurate information as possible.Check out NARPM.com, BP’s Property Manager Finder, etc.Also, encourage you to learn from the mistakes of others - by reading posts here on BiggerPockets about owners not having their expectations met by their current Property Management Company.

Properties that attract lower quality tenants (more headaches) tend to cost less and have higher returns relative to the more desirable areas. 

Who can provide a referral or insight on managing this rental?

3.Any tips for managing cash flow and leveraging existing assets to keep growing my portfolio?

For instance, I was once thinking about buying a property that had a minor issue with a relatively easy solution, but then we learned from the City that implementing that solution would create a new problem that would have cost us $50k+ to address in order to retain a certificate of occupancy (I didn't know what I didn't know, but I'm glad I found out before I bought the property!). 

Third, develop a property management model and plan to keep expenses low and revenue high.
