Where clients come from

  1. The first 90 days

    New owners read the electricity and gas distributors for the address and the weather it sees, and plan service or replacement.

  2. Closing and moving

    Around closing, the closing checklist names rental equipment on title, such as a rented furnace or water heater.

OfferDue's tools for this work

Each is sold once, at a flat price that is the same for every business; none is billed monthly. One that is not open to buy yet says so on its page.

What OfferDue does and doesn't do with this business:

  • Listing is free and shows in the order businesses were checked: no business pays for a place, a label or an order on any page.
  • OfferDue takes no fee for a client who finds a listed business, and pays none to anyone for a client.
  • OfferDue's pages say what each record shows and where it comes from: never legal, financial, insurance or inspection advice.

Public-record information, not legal, financial, insurance or inspection advice. A listing on OfferDue is not a recommendation; check licences and references yourself.
