An expired domain does not have one objectively correct price. Its value depends on the name, the buyer’s intended use, the evidence available and the terms of acquisition. Your practical aim is to produce a defensible range and a maximum purchase price, while keeping uncertain assumptions visible.

Separate three numbers: what you might pay, what you would ask when selling and what comparable buyers have actually paid. Treating an appraisal estimate as all three is a common way to overbid.

Establish what is available to buy

Record the domain, extension, current listing and acquisition route. Expired does not mean unregistered. ICANN’s typical gTLD lifecycle separates expiry from later stages that can include restoration and deletion. Confirm the auction or registrar terms, possible renewal by the previous registrant and any delivery conditions.

Next, define the asset. A domain-only purchase normally requires a different valuation from a website with verified earnings, content rights and operating costs. Do not include a former business’s revenue or audience merely because it once used the address.

Assess the name without looking at metrics

Write one sentence explaining who could use the name and why. Consider natural wording, spelling, length, pronunciation, extension fit and whether the name is narrow enough to limit its audience. Identify plausible classes of buyers rather than assuming a specific company will want it.

Check potential conflicts before turning that idea into a price. WIPO’s UDRP guide explains trademark-based domain disputes. A name that appears attractive mainly because it resembles an established brand may carry a risk that outweighs its apparent resale potential.

Then review the domain’s previous use, important backlinks and any traffic evidence you can legitimately obtain. A high authority score is a research prompt. Age alone and a large link total do not establish a premium. Separate verified observations from seller claims and missing information.

Select comparables you can explain

Use reported completed sales, rather than current asking prices, to investigate what buyers have paid for similar assets. Match the extension, word structure, subject and likely buyer type as closely as practical. Record the sale date, venue, currency and any uncertainty about what was included.

Historical sales services can help gather evidence. NameBio’s own documentation describes recorded sales and filters including date, extension and venue categories. Such a database is useful evidence, but it is not a complete account of all transactions or of names that failed to sell.

If your closest comparisons are investor auctions, avoid presenting their prices as established retail values. If only exceptional sales resemble the name, explain why they may overstate its prospects. A range based on several imperfect comparisons is more honest than a precise number based on one spectacular sale.

Use an automated appraisal as a cross-check

An automated estimate can highlight a comparison or naming factor you missed. It should not set your bid automatically. GoDaddy’s GoValue documentation explicitly explains that actual sales may fall above or below its estimate and that it makes no purchase or sale guarantees.

Our appraisal tools guide and report interpretation guide help distinguish the output from the evidence behind it. If the tool estimate contradicts your comparisons, investigate the disagreement rather than averaging the numbers mechanically.

Turn the range into a purchasing limit

Suppose, hypothetically, your research supports considering a future sale around £1,200. Assume a 20% selling commission, £40 of holding costs, £60 of other transaction costs and a desired £400 margin before tax. Commission would be £240, leaving £960. Subtracting the other costs and margin gives a £460 acquisition ceiling.

That ceiling is conditional on the sale happening at the assumed price. At a £700 sale, the same commission rate leaves £560; subtracting £40, £60 and a £460 acquisition leaves £0 before tax. If there is no sale, acquisition and renewals remain costs. These are planning scenarios, not forecasts.

Use the domain flipping ROI guide to include unsold inventory in the wider budget. Set a lower limit if the evidence is weak, your holding period is long or the domain would have little usefulness without a resale.

Keep a valuation note you can revisit

Save the comparable records, check date, observed history, current fees and reasoning for the range. Mark confidence as strong, limited or speculative, with a sentence explaining that judgement. Reassess when costs or evidence change.

Before bidding, read your note again. A useful valuation lets you explain both why the domain interests you and why you will stop at a particular price. If you cannot identify a credible use or support the assumptions, declining the purchase is a valid result.
