Buying art as an investment.

Buying art as an investment fails most often at the first step, not the last. Collectors who start by browsing end up owning whatever they happened to see; collectors who start by defining an area end up owning a collection.

Set three things before you look: a budget you can leave untouched for seven to ten years, a holding period you genuinely mean, and one or two areas — a period, a medium, a group of artists — you are willing to learn properly. Depth beats breadth every time, because the whole edge in art is knowing what a good example of a specific thing costs.

Then look at far more work than you buy. A working reference for pricing takes months to build and is the difference between negotiating and guessing.

There is no single entry point to art investment, but there is a sensible thing to do at each level. The ranges below are the way we actually advise, not a price list.

Auction is transparent on price and unforgiving on everything else. The estimate is a marketing device, the buyer's premium adds roughly a quarter to the hammer, and the work is sold as seen — condition problems discovered afterwards are yours. Attend the view in person or commission a condition report before you bid, and set an absolute ceiling before the room warms up.

A dealer or adviser negotiates privately, sees material before it reaches public sale, and carries reputational responsibility for what they place. You pay for that in the margin, and you get access, information and recourse in return. Ask any dealer directly how they are paid.

Art fairs are efficient for seeing a lot in a short time and for meeting galleries you would otherwise never encounter. They are also engineered for fast decisions. Use a fair to look and to start a conversation, then take the decision off the stand.

Online is now a routine part of the market and works well when the seller will put condition, provenance and dimensions in writing and will accept a return. The fraud to guard against is invoice interception: verify bank details by phone with the gallery, using a number you sourced independently, before transferring funds.

Six checks decide whether an asking price is defensible. Run them before you negotiate, not after — questions asked after a deposit rarely improve the outcome.

The price is rarely the price. At auction, add the buyer's premium and any applicable VAT or artist's resale right. Everywhere, add specialist transport and crating, framing or conservation where the work needs it, and the first year of insurance.

Then plan for the ongoing cost of roughly one to two per cent of value a year across insurance, storage and conservation, and for the exit, where seller's commission and buyer's premium together can consume up to a quarter of what the next buyer pays. A work has to appreciate meaningfully before a sale simply breaks even.

We set all of this out in writing before a purchase, so the number you approve is the number you pay.

Photograph the work front and back on arrival and keep the images with the invoice, certificate, condition report and any exhibition or publication history. That file is your provenance, and it is worth real money at resale.

Insure at replacement value with a specialist policy rather than a household contents extension, and review the sum insured every few years. Hang away from direct sunlight, radiators and damp external walls; store climate-controlled if the work is not on display.

Then leave it alone. The most common unforced error in art investment is impatience — bringing a work back to market too soon, where a failed sale is publicly recorded and follows the work for years.
