Constaia

Rental applications

Pay stubs, bank statements and IDs reviewed as applications arrive

Income and identity documents for rental applications, with math, dates and names checked.

The problem

  • Applicants upload stubs, statements and W-2s in every format.
  • Old stubs, and statements in someone else's name.
  • Edited documents that look fine at a glance.

With Constaia

  • Pay stub math and bank statement balances reconciled; ABA routing checksum validated.
  • max_age_days and holder checked against the application.
  • Possible-edit warnings to prioritize manual review.
  • Constaia is not a consumer reporting agency and does not provide consumer reports. It checks the documents applicants give you; screening decisions and fair housing obligations stay with you.
