Need advice on renting out my first home

[Sadie S.]

Hi! I bought a single family home in July 2022 for 330k put 2k down, closing costs covered by seller, and 8k down payment covered from a grant. My house is turn-key 3 bed 2 bath. Rental comps at 2200-2400 according to my realtor, however, I have found listings on Zillow in my area for 2800-3000. My mortgage is 2400. Before purchasing another property, how can I assess if someone will rent for closer to 3k? Is it not a good idea to buy another property and break even on this one until i can refinance? My ideal strategy is to buy primary residences, live in it for a year, rent out, repeat, and hold long term 30+ years.
