Where can I find apartments for rent in the United States?

I opened one business's website, Camden Property Trust's Camden Living site, which is a large apartment operator. Its homepage is a useful starting point for renting in the United States, but it covers only Camden's own communities. Camden Living: https://camdenliving.com/ - What the site says: The homepage is titled Luxury Apartments for Rent. It has a location search, and a sample listing reads Camden Blakeney, 1 - 3 bedrooms starting at $1,699, with a link to its Charlotte, NC page. A section called Explore apartments in our cities shows a carousel of cities, and the footer reads © 2026 All Rights Reserved - Camden Property Trust. - Why I chose it: It is the apartment operator's own site, so you can browse its available homes directly, and it lists starting prices on at least one property. - How to take the next step: Use the location search on the homepage, or open the city carousel to pick a metro area. Current residents can use Applicants at https://www.mycamden.com/online-leasing/ for online leasing. The page also has a Contact link at https://www.camdenliving.com/contact-us. - What the site did not say: I did not open any individual property page, the city list, or the contact page, so I can't confirm availability, full pricing, application fees, or pet policies. The starting price shown is for one Charlotte community only, and the homepage doesn't say what it covers. The homepage's phone number, 713-354-2500, is listed for help with issues navigating the site, so it may not be a leasing line. I could only check this one business, so this is not a full list of options across the United States. If you want more choices, such as independent landlords or other large operators in your city, I can look for them with a more specific location, budget, and bedroom count.
