How the Tech Bros Shop for a House

The open-house ritual used to be simple: peek in the closets, flush the toilets, squint at the water heater and hope for the best.

Then the tech guys showed up with their phones out.

Some software engineers shopping for homes have turned the walk-through into a data-gathering exercise.

One buyer house hunting this summer photographed the furnace, air conditioner, and water heater — the metal boxes many buyers barely glance at.

He fed the pictures into an AI chatbot and asked it to read model plates and serial numbers, estimate the age of each unit, and give him a rough idea of how much useful life might remain.

Upstairs, he leaned out a bedroom window and photographed the roof.

Then he asked the chatbot to look at the shingles, flag visible wear, and estimate whether replacement might be coming soon.

By the time he walked out the front door, he had a rough repair budget in his pocket.

That can matter.

An aging furnace may become a point of negotiation.

A roof that appears near the end of its life can make one house look very different from another.

He is not alone.

About 39% of prospective buyers have used AI tools during their home search, according to a Veterans United survey cited for this report.

Real estate agents are also seeing more buyers arrive with chatbot-generated price opinions in hand, according to CNBC.

Sellers are experimenting with the tools too.

Fortune reported that a homeowner in Cooper City, Florida, listed his house $100,000 above what local agents recommended after consulting ChatGPT and had a signed contract at that price within five days.

The cautions are important.

AI repair estimates can rely on outdated pricing, and a photograph cannot reveal everything that may be wrong with a house.

It cannot see a cracked heat exchanger inside a furnace or a soft spot beneath roof shingles.

It cannot tell whether a foundation problem is cosmetic or serious.

And it cannot replace a licensed home inspector.

But as a first pass — before earnest money, inspection fees, and repair negotiations — the phone in your pocket can give you a useful list of questions to ask.

No chatbot has ever crawled through an attic in August.

For now, that still matters.
