Whether you\u2019re a nosy neighbor, a real-estate agent, a potential homebuyer or seller, or all of the above, you\u2019re going to want HomeSnap on your iPhone. Just don\u2019t expect it to always be a snap.\n\tHomeSnap is a free iOS app optimized for iPhone\/iPod touch screens (current version is 1.10). To use the app you simply take a photo of a house with your iPhone camera. HomeSnap then serves up vitals on the property, such as its asking price if it\u2019s for sale or how much it\u2019s worth or recent sale price if it\u2019s off the market. You get other details, too, such as number of bedrooms and bathrooms; one or more photos; and listings of nearby schools and similar properties.\n\tIf a home you snap is for sale, HomeSnap delivers much of the same information you\u2019d get from the listing agent\u2019s marketing flyer, such as features and amenities, and homeowners dues (if it\u2019s a condo). HomeSnap will also tell you how long the property\u2019s been on the market\u2014something a flyer probably won\u2019t tell you. And you can sign up for email alerts to be notified when the property price changes or the home is in contract or sold.\n\tHomeSnap is by no means the only smartphone real estate app. But its use of the iPhone camera and GPS to give you property details is impressive. (The app developer says an Android version is coming soon.)\n\tHowever, HomeSnap doesn\u2019t always make it easy to get the details you want. In the majority of my tests, HomeSnap didn\u2019t correctly identify the property I\u2019d photographed. I had to sort through several home listings in the app until I found the correct one. On a few occasions, the home I photographed wasn\u2019t even among the choices HomeSnap offered. Given that I only photographed properties under sunny skies and with few if any obstructions, I was hoping HomeSnap would be a bit more precise.\n\tHomeSnap was developed by real-estate online-broker Sawbuck. If you see a home for sale you want to visit, you can click a \u201cGet Inside This Home\u201d link to see two additional options: \u201cCall a Sawbuck Advisor\u201d or \u201cSchedule a Visit\u201d with a Sawbuck agent. While you\u2019ll find the listing agent\u2019s name and their brokerage firm at the bottom of the information HomeSnap provides, the app doesn\u2019t provide contact information. In other words, Sawbuck\u2019s hope is that HomeSnap will funnel new clients its way, which is a smart marketing move.\n\tHomeSnap isn\u2019t just for buyers on the prowl for properties. I can imagine it being useful to sellers, too, who could drive around with their iPhones, snap photos of properties and find comparable sales in their neighborhoods. They'll probably want to be discreet about it, however; people often become anxious when they notice someone photographing their homes. That practice may put you into another category of potential HomeSnap users: the nosy neighbor.
