What the numbers mean, and what they cannot mean

• Property record and characteristics from public records data
• Transaction history for the address, including recorded sales and financing events
• National house price index data
• Metro-level and, where coverage allows, ZIP-level house price index data

Estimated value is an estimate produced from these inputs. It is not an appraisal, a broker price opinion, or an offer.

The rating runs from 0.0 to 10.0 and describes the property only. It is a weighted blend of four components:

• Relative appreciation against the local benchmark, 40 percent
• Long-term appreciation, 25 percent
• Market resilience through downturns, 20 percent
• Appreciation consistency, 15 percent

Debt is excluded on purpose. A mortgage balance says something about an owner, not about a house, so it never moves the rating.

If the minimum evidence is missing, the report shows the rating as unavailable rather than guessing. That happens when recorded property history for the address is still limited, or when national or metro benchmark coverage cannot be established for the address. A missing rating is a statement about our evidence, not a judgment about the home.

Where a standard measurement window does not fit the ownership period, we measure from the purchase date to the present for spans long enough to be meaningful. If the transaction history shows a refinance or cash-out event, principal reduction is reported as unavailable rather than inferred, because the original amortisation no longer holds.

Any balance you type into a report is used only to draw the equity view on your screen and in a PDF you download yourself. It is not sent to our servers, not stored, and not included in analytics.

Every stored report shows the date its data is current to and marks itself when it has aged past our freshness window. If an address looks wrong on a report, the report page links to a correction path and we handle it by hand. See contact.

Estimates cannot see condition, renovations that were never permitted, a difficult neighbour, or a roof about to fail. Treat a Home Wealth report as one input to a decision, alongside an inspection, an appraisal, and professional advice.
