Repairs and quotes

From “the water heater is leaking” to a booked plumber.

Log the repair, collect quotes from as many contractors as you like, and see the lowest at a glance. The price on a repair always says what it's based on: an accepted quote, the lowest so far, or the final bill.

AI property inspection

Coming soon

Soon: a photo in, a list of what to check out.

This one isn't built yet. The plan: you'll upload a photo of a property, AI will flag likely problems — missing shingles, a sagging gutter — and you'll decide which ones become repair tickets. Try the mockup below to see the idea.

Repairs

Nothing yet. You decide what becomes a ticket.

When it ships: AI suggests, you confirm. Nothing will happen without your approval.

Projections

Will this place pay for itself, and when?

A year-by-year cash-flow forecast that starts from your own records. Move the sliders; anything that isn't from a record is marked as an assumption.

How it works

Your records stay yours. Here's how.

Pages are rendered on the server, every form goes through a checked server action, and the database itself refuses to show one landlord's data to another.

Your browser

  • React 19 pages
  • Every form posts to a Server Action

Next.js server

  • Checks who you are on every request
  • Validates every write with Zod
  • Server-only modules for uploads and encryption

Supabase

  • Postgres with Row-Level Security
  • Auth (email + password)
  • Private file storage

The server, and only the server, also calls

Public data, server-side only

  • County parcel and sales records
  • Census and HUD rent data
  • Local news feed

Your data is walled off from every other landlord

Three checks on every request: a route guard, a signed-in check on every page and action, and Postgres Row-Level Security as the last word. Asking for someone else's property returns a 404.

Records can't point across accounts

Every tax bill, repair and quote is tied to its property and its owner together, so the database itself refuses a record that crosses users.

Private file storage

Uploaded bills and policies sit in a non-public bucket. Opening one creates a link that expires after 60 seconds, and that link is never written into the page.

Uploads are checked, not trusted

PDF, JPG and PNG only, identified by the file's actual bytes rather than its name. 10 MB cap, server-generated file names, path tricks rejected.

Policy numbers are encrypted

Insurance policy numbers are encrypted with AES-256-GCM before they're stored and shown masked, like ••••1234.

Every change is logged

Database triggers record each insert, update and delete, with the values before and after.

Built with

  • TypeScript
  • Next.js 16
  • React 19
  • Tailwind CSS v4
  • Supabase
