Data sources

A RenIQ report combines a small number of clearly-bounded sources. We would rather show you where a figure comes from than present a single confident-looking number with no provenance. Every report also carries a data-confidence marker so you can see how much of it rests on observed evidence versus modelled assumptions.

1. Your inputs

The purchase price, expected rent, and any costs you enter are the primary inputs. When you provide a listing URL, we fetch the page and use AI to extract structured fields (price, size, rooms, location, listed rent). You can review and correct every extracted value before a report is generated. If you leave an optional field blank (rent, operating costs, renovation), RenIQ substitutes a conservative, clearly-labelled estimate rather than a silent guess.

2. Comparable listings

To judge price and rent against the local market, RenIQ gathers comparable properties from public listing pages, the same portals a buyer would browse. Comparables are matched by property type, a size band around the subject property, and location.

Two limitations matter, and we state them plainly on every report:

• Comparable prices and rents are asking prices from listings, not recorded transaction values. Actual sale prices in Slovakia and Spain are not publicly available at the individual-property level, so asking prices are the best public proxy. They tend to sit above eventual sale prices.
• Each cited source is automatically checked to be a real, reachable public web page. That confirms the source exists. It is not a guarantee that the page substantiates every figure attributed to it. Always confirm material facts directly at a viewing or with the selling agent.

3. Country financial defaults

Where you do not provide a figure, RenIQ applies conservative, country-specific defaults: mortgage rate and term, loan-to-value, vacancy allowance, maintenance/CapEx reserve, and the tax model. These are configured per market (Slovakia and Spain), updated periodically rather than in real time, and listed in full on the methodology page.

4. Residential price indices

The appreciation estimate that feeds a report's first-year Total Return is drawn from residential price-index data where it is on file for the region, and a conservative country default otherwise. Appreciation is deliberately kept out of the yield and cash-on-cash figures. It only ever contributes to the clearly separated Total Return line.

What RenIQ does not use

RenIQ does not access live market feeds, current-minute mortgage rates, official property registers, or any private MLS. Everything in a report is derived from your inputs, publicly available listing pages, and the reference data described above. AI is used only to read pages and write the narrative, never to compute the numbers, as described in our AI-use disclosure.
