How it works

01

Today’s price is only half the story.

Listing sites show you what an apartment costs now. Arizona Rent Tracker shows you what it cost last week, last month, and whether it’s about to drop.

Where the prices come from

02

Every morning we check the advertised rent on the landlords’ own websites, for 187 complexes so far. We record the price and keep it, so each complex builds a price history over time.

Older history

03

History before we started checking daily comes from the Internet Archive’s Wayback Machine, which saved copies of these same landlord pages. We read about one saved copy per week, so older history is weekly rather than daily. It goes back to Jul 22, 2019 for some complexes.

What the numbers mean

04
  • Starting at is the lowest price the landlord advertises, usually for the smallest unit on a specific lease length.
  • Specials like “weeks free” are tracked separately. Advertised rent usually doesn’t include them, so what you pay can be lower.
  • Total vs base rent: where a landlord shows both, total rent includes required monthly fees.
  • Some landlords show prices per floor plan; others show one starting price for the whole complex. Each page shows what’s available.

Public records

05

For Phoenix and Mesa complexes we show city code-enforcement complaints (things like broken AC, pests, or leaks reported to the city) and, for Phoenix, eviction filings from Maricopa County Justice Courts data. They’re matched to each complex’s main address, so counts are a floor. A complaint isn’t a confirmed violation. We never collect tenant names or contact details.

What this isn’t

06

These are advertised prices, not signed leases. Prices change daily and depend on the unit, lease length and move-in date. Always confirm with the property. We’re not affiliated with any landlord, and we don’t sell pricing data to landlords.

About our crawler

07

Our crawler is called ArizonaRentTrackerBot. It reads each landlord’s public floor-plans page once a day, at about 6:00 a.m. Arizona time, and records only the advertised price, floor plan, availability and special. It never collects personal information.

It follows each site’s robots.txt rules and never gets around a site’s bot protection. To stop it, add this to your robots.txt and it won’t visit again:

User-agent: ArizonaRentTrackerBot
Disallow: /

To let it read a page your bot protection blocks, allow requests whose user agent contains “ArizonaRentTrackerBot”.
