Dear [first name],
City records show an open code case on [property address]. Repair orders come with deadlines and fines, and fixing everything is not always worth it.
I buy houses as-is, including the repairs the city has asked for, so the case stops being your problem.
The app fills in each owner's name and address and prints envelopes or labels.
What you get in the app
- Every property on the list, with owner and mailing address
- Likely-to-sell score 1–10 and the reasons
- Stack with absentee owner
- Map, property history, export one row per property to Excel / CSV
- New owners on the list every Monday
The score and the reasons on every owner show who is under the most pressure, so you start with the best odds.
