Comps and rents are only as good as their locality. Here's why accurate real-estate data is a geo-IP problem — and how to assemble a clean cross-market dataset.
Property portals serve listings, prices, and availability by visitor location, and many are region-locked. To collect accurate comps and rents, query each market from an IP physically in it — US portals from US IPs, UK from UK IPs. A geo-diverse residential/mobile pool (17+ countries) lets you assemble a consistent cross-market dataset for valuation, yield modelling, and pricing tools. Same geo-truth principle as travel pricing.
A comp from the wrong market isn't a slightly-worse comp — it's noise. Real-estate value is intensely local: the same property attributes price differently block to block, let alone country to country. Because portals key their output to the visitor's location, the only way to capture a market's real prices is to appear to be in that market. That turns "data quality" into an infrastructure question — how broad and how local is your IP coverage.
For AVMs, investment screens, and rent-estimate tools, that's the whole game: collect sold and listed comps plus rental asking rates, per market, on a schedule, through local high-reputation IPs, and you have a defensible dataset. Skimp on geography and the model inherits the distortion.
Property portals serve listings, prices, and availability based on the visitor's detected location, and many are region-locked entirely. Collecting US comps from a UK IP, or UK rents from a US datacenter IP, returns distorted or empty results. To get the data a local buyer or renter actually sees, you query from an IP physically in that market — so the comps and rents reflect reality.
Comparables ("comps") are recently sold or listed properties similar to a subject property, used to estimate value. Collected systematically across neighborhoods and time, they power automated valuation models (AVMs), investment screening, and pricing tools. Rental comps do the same for rent estimates and yield modelling. Accuracy hinges on local, current data.
With a geo-diverse proxy pool you collect from each market through a local IP. PROXIES.SX covers 17+ countries with real mobile and residential IPs, so you can gather comps and rents market-by-market — US portals from US IPs, UK from UK IPs, and so on — assembling a consistent cross-market dataset.
