Here in Silicon Valley, many agents have come to expect their real estate clients to be a bit high tech. Suggest they bring a pen and paper to take notes on all the houses you show them this Sunday and you may get puzzled looks. Pen and paper? That’s so old-school.

Wow them a bit more by suggesting an app for that: House Hunter.

House Hunter is an iOS app that works on iPhones. It makes it easy to take notes while house hunting and organize features and priorities so you can remember later and compare the homes you’ve seen.

It’s good practice anyway to have your buyer clients list out priorities for their home before you start looking at properties. House Hunter captures it all and uses the priorities to score homes your clients see against what they’ve deemed important. And after they’ve seen a handful of houses, most people naturally start to forget details about each one – or remember things a bit differently.

Another cool feature is that your clients can share their notes with you. Now you know where their heads are at: is it really the fireplace or the extra office space that will break their decision? Remove the guessing and give them details to compare.

House Hunter also has a mortgage calculator – always a good thing (if it works well, that is), and stores photos (nothing jars the memory quite like a good photo).

I can also see this app coming in handy for yourself when on broker tours. You can refer to your notes and images later and remember what you’ve seen – and easily share with clients. Then you have it for easy reference on your phone later too.

The app costs $3.99 in the iTunes store. Give it a test run and see whether this could be a solid decision-making aid when searching for the next perfect home.
