How many viewings are enough

Two failure modes bracket every room search. One person takes the first room they see because it seemed fine and they were tired. The other views eleven rooms, develops elaborate opinions, and loses each of the good ones to somebody who decided faster.

Both are the same error: no model of how many viewings the decision actually requires. It isn’t a matter of thoroughness. It’s a question about what a viewing adds, and viewings stop adding much sooner than most people expect.

What each viewing is for

The first viewing calibrates. You learn what the advertised figure buys in this area, what a room of that description actually looks like, and how much wide-angle distortion to discount. Almost none of its value is about that particular room.

The second and third build the comparison. Now you can tell whether a room is good or merely inoffensive, because you have something to hold it against.

The fourth onwards is where it gets interesting: mostly you’re confirming a judgement you already formed, and the marginal information drops off sharply. You’re no longer learning about the market. You are shopping, and in a competitive market shopping has a cost.

The number, and what changes it

Three to five viewings is the shape of a good search in most markets. Fewer than three and you have no baseline, which is the specific reason first-room decisions go wrong: not that the room was bad, but that you had no way to know.

What pushes the number up: an unfamiliar city, an unusual requirement, a wide area, and a slow market where listings sit for a while. What pushes it down: a tight market where good rooms go the same day, a hard deadline, and a clear sense of what you need.

The dominant variable is market speed, and you can measure it directly. Watch a handful of listings you liked but didn’t pursue. If they’re gone within a day or two, you are in a market where the fifth viewing costs you the third room. If they’re still up next week, you have room to be leisurely.

Cluster them

Whatever the number, see them close together. Two viewings on the same evening compare far better than two a fortnight apart, because you’re comparing rooms rather than memories, and memory of a flat degrades quickly and flatteringly.

Booking three or four in one weekend also removes the worst dynamic in a slow search: viewing one room, feeling uncertain, waiting, and then evaluating the next one against an idealised version of the first.

Leave enough time between them to see the place properly and to get across town. Back-to-back viewings half an hour apart produce two rushed half-look-arounds and no useful comparison.

Keeping the record

Write four lines immediately after each one, before you get on the train. Not later — later you will have compressed it into a single adjective.

What’s good about it. What’s actually wrong with it. What you still don’t know. Whether you’d be comfortable saying yes today.

That last one is the useful question, and it changes as the search progresses. The room that was a maybe on Tuesday sometimes reads as a clear yes on Saturday, purely because you now know what else is out there. The record is what lets you see that rather than just feel it.

Deciding while options remain open

The hard part isn’t the count. It’s that in a competitive market you’ll be asked to decide on room two while rooms four and five haven’t been seen.

The workable rule: you may commit to a room you’d be genuinely happy in, at viewing two or later, without seeing the rest. What you shouldn’t do is commit to a room you have doubts about because you’re tired, and you shouldn’t hold out for a hypothetical better room once you’ve found a good actual one.

If you’re at viewing one and it’s excellent, the honest move is to ask for a short window rather than either committing blind or losing it — a day is often available and reasonable to ask for. Whether that hold involves any payment is a separate matter, and the rules about that are the ones that don’t bend.

Flag check

FLAG CHECK — the pace of the decision

  · Asked to decide on the spot, at the
    viewing, with no window at all
                    → pressure tactic in most
                      contexts. Ask for a day.

  · Told several other people are interested
                    → NOT A FLAG. Frequently true.
                      Doesn't change what you'd be
                      agreeing to.

  · Room is still advertised a fortnight later
    at the same price
                    → not a flag, but a question.
                      Something is putting people
                      off.

  · Any money to hold a room you haven't
    stood in
                    → WALK AWAY.

  · Lister happy to give you a day to think
                    → NOT A FLAG. This is what a
                      normal household does.

  · You've seen eight rooms and rejected all
    of them for small reasons
                    → look at yourself, not the
                      rooms. The list has become
                      a defence mechanism.

When more viewings genuinely help

Two situations. First, when you can’t articulate what’s wrong with the rooms you’ve seen — that usually means your criteria are still forming, and more looking is the way to form them.

Second, when your requirements are unusual enough that the market has few matches: a specific area, a pet, an odd start date, a need for a genuinely quiet room. There the count is high because the hit rate is low, not because you’re deliberating.

The situation where more viewings don’t help is the common one: you’ve found something good and you’re looking for permission to stop.

What a viewing count can’t tell you

Nothing about whether you chose well. Some people view twelve rooms and get it wrong; some take the first and are happy for three years. Viewings reduce a specific kind of error — the one where you didn’t know what was available — and they do nothing about the rest.

More importantly, the number of viewings has no bearing on the things that decide a share. Noise at two in the morning, water pressure at eight, whether the housemate who was charming in the kitchen is someone you can live with in February: none of that is in the sample, however many times you sample it.

Three to five viewings is enough because five viewings and fifteen viewings are equally blind to the same things. Get the baseline, form the judgement, and stop.
