The data that disappears at closing
Everything about a home is known at exactly one moment, and then it scatters. Here is what gets lost, and why the timing matters.
A home is the most thoroughly understood it will ever be on the day it changes hands.
The builder knows which breaker runs the kitchen. The inspector knows the age of the roof. The previous owner knows the upstairs fan trips the same GFCI as the garage, that the water heater was replaced in 2021, and which filter the fridge takes. For one afternoon, every detail about the house is in the room.
Then everyone leaves, and it scatters.
Where it goes
Some of it lives in a binder that ends up in a drawer. Some of it stays in the previous owner's head and walks out the door. Most of it was never written down at all, because nobody had a reason to. The buyer nods through the walk-through, certain they will remember. Within a week they have forgotten the breaker, the filter, and where the water shutoff is.
So the next time something breaks, they start from zero. On their knees behind the water heater with a phone flashlight, reading a model number off a sticker. Calling three contractors before one works on that system. Texting the previous owner, who has also forgotten.
None of this is hard knowledge. It is just lost knowledge.
Why the timing matters
You cannot reconstruct a home's details later, at least not easily. The cheapest moment to capture them is the one moment they are all present: the close. After that, every fact gets more expensive to recover, and some become impossible.
That is the bet behind Helm. Capture the home once, at the close, room by room, while someone still knows. Hand it to the owner as something they keep for as long as they live there. When the dishwasher stops draining at 10pm, the answer is two taps away instead of a crawlspace and a flashlight.
The data does not have to disappear. It just needs somewhere to go.
