A research layer for rental markets
RentMarker turns public US housing, employment, migration, supply, affordability and climate records into a consistent research surface. The aim is to answer the market question before a buyer spends time underwriting individual listings: what is measured, what is changing, where the risks sit and what still needs local verification.
A location page keeps its figures, release periods, definitions and source trail together. A comparison page is published only for a reviewed pair with a material decision difference. A tool uses the same prebuilt evidence rather than inventing a second set of numbers at runtime.
What the site publishes
Metro pages carry the broadest market evidence and the only composite score. County pages add local housing stock, labor, migration, hazard and municipality context. City pages focus on the place-level price, rent, household and nearby-market evidence that can be supported without pretending a city is a metro.
State pages summarize their measured metros and counties; research studies reproduce a defined join across datasets; rankings and interactive tools help narrow the catalog. These scopes are linked, but their figures are not substituted for one another.
A practical way to use it
Start with the national rankings, the evidence map or the opportunity matrix. Open a location to read the underlying series and risks, shortlist only the markets that still fit the thesis, and compare a small number of reviewed alternatives.
Only then move to a property. The cash-flow test makes financing, vacancy, maintenance and expense assumptions explicit, but those inputs must come from the actual deal. A market median is a screening fact, not a pro forma.
Independence and incentives
RentMarker is an independent research product, not a brokerage, lender, appraisal service or listing marketplace. The current release has no sponsored rankings, paid placement or lead-resale program. A source does not receive a better presentation because it is commercially prominent.
Source selection is based on geographic usefulness, release quality, reproducibility and permission to use the published research data. If the business model changes, the relevant disclosure and policy pages must change with it.
The boundary of the evidence
RentMarker does not value a property, predict appreciation, inspect a building or know a reader's financing, tax position, insurance quote and operating skill. Metro, county and city summaries describe an area; they do not describe a particular address.
Missing evidence remains n/a. A reproducible error should be reported through Contact and corrections so the underlying pipeline can be fixed for every affected page. The scoring definitions and current source catalog are public in Methodology and Data sources.
