Enrich
Add owner contact data from multiple sources
Run contact, mail, compliance, location, and web-research enrichments only where they are worth the cost.
Select only the rows and fields that need more data.
Use provider waterfalls when one source is not enough.
See credit estimates before you run an enrichment.
Included property data
Every list starts with real property data
Property lists include ownership, property characteristics, valuation, tax, sale, mortgage, and location fields by default. Add enrichments later when a row needs owner contact data or another field.
Included fields
178
Property, ownership, tax, sale, mortgage, value, and location fields are included before any enrichment credits.

Fair pricing, no traps
Clear pricing before you run a list
Property data tools should not make cancellation hard, hide enrichment costs, or push users into expensive plans before they know what works. Affix keeps the workflow and costs visible.
Cancel yourself
No support ticket, phone call, or retention runaround required to cancel your plan.
Know what credits cost
See enrichment costs before you run a list, so you can decide whether the extra data is worth it.
Start small
Use the free plan or a lower monthly plan before scaling into larger lists and enrichment runs.
Pay for useful data
Enrich the rows that matter instead of paying for bloated bundles you do not need.
FAQ
Plain answers
What does Affix do?
Affix helps you find properties, upload property spreadsheets, enrich owner data, review the results, and export a clean list.
Can I upload a CSV?
Yes. You can import CSV or Excel files, keep the original rows visible, match property addresses, and enrich selected records.
Can Affix find owner contact data?
Affix is built for owner and contact enrichment workflows. You choose what to enrich, how providers should run, and what results are ready to export.

How are credits used?

How is Affix different from PropStream or ListSource?
