Rentometer is a fine quick check: it averages the asking prices around an address, nationwide. The catch is in the word asking. An asking price is a hope. Property Priors watches every tracked Memphis rental night by night to the day it leases, so the number you get comes from rents that actually happened, plus the one number no average can give you: how many days it takes to lease.
Every grade above is computed from our public accuracy ledger, regraded weekly, misses included. See the ledger.
The honest trade: Rentometer covers the whole country and Priors does not. If you are comparing markets nationally, keep the national tool for scouting. When the address you actually care about is in Memphis, use the tool that watched the leases happen.
For Memphis addresses, yes: it answers the same question from tracked leases instead of asking-price averages, adds days-to-lease, and grades itself in public. Outside Memphis it is not, and we say so plainly.
We grade our own reads against the rent each tracked listing actually leased at: median 8.2% off across 2,049 rentals, with the misses published on the accuracy ledger. No estimate tool can publish that grade, because an estimate never finds out whether it was right.
The first full read every month is free, no card. Pro is $29 a month with a 7-day free trial and covers unlimited reads, resale value, and Airbnb revenue in the same read.
Most Memphis rentals do lease at their advertised rent, and when they do not, the cut and the wait tell you the ask was wrong. A tool built on asking averages cannot see any of that. A tool built on tracked leases is made of it.
