Rent comps built to defend, not explain away
Every comp cited in an appraisal is a comp that might need defending later, to a lender or compliance reviewer. Get property-level data sourced directly from property management systems, not scraped or surveyed, so the income approach number stands on its own.
Property-level granularity • Never scraped • Localized to your jurisdiction

A comp you cite is a comp you’ll have to defend
County-wide blends don’t survive a reviewer’s questions
The income approach lives or dies on the specificity of your comp. A county-wide blend invites pushback from any reviewer who asks why that number applies to this specific property, in this specific submarket.
Scraped and self-reported comps carry that risk further
Comps pulled from scraping listing sites bring duplication and legal exposure that can surface during a lender review. Survey-based comps are self-reported, collected infrequently, and often reported at a community-average level — neither holds up well under scrutiny.
Comps sourced to stand on their own
Dwellsy IQ delivers property-level data sourced directly from property management systems, not scraped or surveyed, so the number in your income approach doesn’t need a qualifier when a lender or compliance reviewer asks where it came from.
Built for valuation workflows
Property-level comps
The income approach lives or dies on the specificity of your comp. Dwellsy IQ’s unit-level data lets you cite the rent for a comparable property in the exact submarket you’re appraising — not a county-wide blend that a reviewer will push back on.
Scoped to your jurisdiction
National scale doesn’t help you if it can’t drill into the one county or MSA you’re actually appraising in. Coverage can be scoped tightly — a single jurisdiction, a specific asset class, whether the assignment is SFR or multifamily — so you’re not paying for or wading through data outside your territory.
Slots into your existing workflow
Retraining analysts and re-validating models is the real cost of switching a data source in a compliance-approved workflow. A defensible comp layer added to what you already run instead, manual or programmatic, no rip-and-replace required.
Historical trends for trend-line support
When a report needs to show how rents have moved over time — not just where they are today — Dwellsy IQ’s data reaches back to January 2020, giving you a defensible historical baseline instead of a single-point estimate.
Low-commitment access to start
Committing to a large data contract before you’ve proven the comps hold up against your own review standard is backwards. Get scoped, right-sized access so the first engagement is a real evaluation, not a leap of faith.
First-party sourcing, not scraped listings
Comps sourced by scraping listing sites carry duplication and legal exposure that can surface during a lender review. Dwellsy IQ is sourced directly from property management systems — public, owner-disclosed data — built to withstand that scrutiny.

FAQ
How granular is Dwellsy IQ’s rent data — can I get a comp for a specific property, not just an area average?
Dwellsy’s data is hyper-local. Every record is unit-level, with final asking rent, 50+ attributes and 250+ amenities tied to a specific rental unit. You’re not working from a county or ZIP-code blend.
Can I scope data to just my jurisdiction instead of buying national coverage?
Yes. Coverage can be scoped to a specific county, MSA, or asset class, which is how most appraisal engagements actually work — right-sized, not national.
Will these comps hold up under lender or compliance review?
Dwellsy IQ data is sourced directly from property management systems — public, owner-disclosed listing data, never scraped, never surveyed. That sourcing model is built to be defensible under exactly that kind of scrutiny.
Do I have to change my whole appraisal workflow to use this data?
No. Dwellsy IQ is designed to slot into your existing valuation process as an additional, defensible comp source — not to replace the models or workflows you already have approved.
How is Dwellsy IQ’s data different from scraped comp data?
Scraped data is pulled from listing sites, which introduces duplication, staleness, and legal exposure. Dwellsy IQ is sourced directly from property management systems through the Dwellsy marketplace — continuous, deduplicated, and legally compliant.
How is Dwellsy IQ’s data different from survey-based rent data?
Survey data is self-reported, collected infrequently, and often reported at a community-average level. Dwellsy IQ captures final asking rents directly at the unit level, updated continuously.
How far back does historical data go?
January 2020 to present, which supports trend-line analysis for reports that need to show rent movement over time, not just a current snapshot.
Is there an API for firms that run their own valuation models?
Yes. API IQ delivers unit-level or aggregated data programmatically, filterable by geography, property type, or attribute.
Can we test the data before committing to a larger contract?
Yes. Scoped, lower-commitment access is available so you can validate the comps against your existing review standard before expanding.
What asset classes does Dwellsy IQ cover?
SFR (single-family rental) and multifamily — all within the same dataset and sourcing standard.
Does the data include any private or personally identifiable information?
No. All data is public, owner-disclosed listing information at the unit level. No PII, no private data.
We’re a municipal appraisal district — can Dwellsy IQ work at that scale and budget?
Yes. Municipal and government appraisal buyers have historically scoped engagements tightly to their jurisdiction and budget, rather than committing to broad enterprise coverage.
