Claremont Avenue sits in the well established heart of Chartwell, on a street of homes that people have held onto for years. Bankwood School is around the corner. Chartwell Shopping Centre is a short walk up the road, close enough to grab dinner on the way home without moving the car. Chedworth Park and Bankwood Park are a few minutes away on foot, and Wairere Drive is close by when you need the rest of Hamilton.

At number 9, there are two homes on one site, and two front doors.

The front home is a 1970s original with three bedrooms, a bathroom and a living area. New carpet and new curtains have given it a fresh start, with the familiar layout of a classic Hamilton home underneath.

Behind it is something entirely new. The second home is a builder’s own: brand new, with two bedrooms, its own bathroom and its own living space. It faces north-west, so the living area and deck take the afternoon sun.

The two homes are well separated by fencing, and each has its own driveway. Close by, but properly apart.

What that means depends on who you are.

For a family, it means everyone close and everyone with a door of their own. Parents can help a son or daughter onto the property ladder. Grown children can make room for Mum and Dad without anyone giving up their independence. Sunday dinner stops needing a drive.

For an investor, whether this is your first property or the next one in your portfolio, it means two homes on one address, in a suburb people want to live in. It is easy to see how it adds up.

Rental appraisals put the front home at $600 to $650 per week and the back home at $540 to $590 per week.

Or you can do both: live in one, and let the other help with the mortgage.

Two front doors. However you choose to open them.
