Linh and Minh, here is your property journey

Preston is the strongest room market we have measured, and it is not close. Eight people searching per room available against 5 registered properties, in a suburb this size, is a genuine supply gap rather than a statistical quirk. Room rent at $278 sits just under Pascoe Vale and Bundoora, but the demand behind it is in a different league. It is also the closest to the city of anything on your list at about 9km, with Regent and Preston stations on the Mernda line and the 86 tram down High Street. The trade is price. A $1,247,000 median is the most expensive entry of the eight, and house prices have moved 36.97% over ten years, which is the softest ten year figure here. So you are paying for location and for a room market that should fill fast, not for capital growth history.

A big, busy suburb that has been steadily improving for years, and the one you named first. The supply gap is the real story: 13 registered properties in a suburb this size is very few, and room rent sits at $265 a week. The demand ratio of 2 to 1 is healthy but not as tight as the other two. Dineth lived here for five years and has bought, renovated and sold here, so we can tell you street by street which pockets to buy in and which to avoid. Trains run from Reservoir, Ruthven and Regent stations.

Be clear about why this suburb is here. On room rent and on growth, Glenroy and Pascoe Vale both beat it. Watsonia earns its place on three things: not one registered property like yours in the entire suburb, and the lowest vacancy rate of the six at 1.45%. It is a smaller, quieter and noticeably better off pocket with its own station and shopping strip. Tenant pools are close. La Trobe University is 3.5km with about 38,000 students, RMIT Bundoora is 4km, the Austin and Mercy hospitals at Heidelberg are about 6km with roughly 1,000 beds between them and round the clock shift work, and the Uni Hill and Polaris business park is 2.4km. Greensborough Plaza is 2km. North East Link runs through the suburb, tunnelling from Watsonia to Bulleen, and opens in 2028. The station car park is being rebuilt as a 630 space multi level facility with a new bus interchange, though the station building itself is not part of that work. It beats the other two comfortably on area quality, which usually means a better calibre of tenant and steadier rent. What lifted it was the room data: rent at $267 a week and zero registered properties like yours across the whole suburb. Zero can mean untapped or it can mean untested, and we will only know once we are operating there. This is the suburb we would like your permission to keep looking in.

Bundoora runs on the 86 tram rather than a train, which puts the top of the city 58 to 61 minutes away. For a tenant heading into the CBD daily that matters. For a La Trobe student or someone working at Northpark it does not, because they are travelling minutes. House prices have moved 37.30% over 10 years but only 0.54% in the last year, so it has been the quietest of the northern suburbs recently. Rents have been growing faster than prices, which is why yields there are expanding.

Greensborough arrived on this list because Stuart assessed a house here, not because we were searching it. The room data says we probably should have been. Four people searching for every room advertised, against just 2 registered properties like yours, in a suburb of this size. Room rent at $269 is a couple of dollars above Watsonia. On the house side it has the strongest ten year growth of anything on your list at 51.35% and the tightest vacancy at 1.05%, both by a clear margin. The honest caution is distance: at about 17km it sits at the outer edge of the range you gave us, one stop past Watsonia on the Hurstbridge line. Everything else about it reads well.

This is the find of the search so far. Room rent at $292 a week is nearly $30 above Reservoir and Watsonia, and $55 above Lalor, and there are zero registered properties like yours across the entire suburb against a measured 2 people searching for every room available. Being 10km from the city with a station in walking distance is the sort of location that holds its value regardless. The caution is that zero registered can mean untapped or it can mean untested, and we will know more once we have walked 102 Derby Street and pulled the full street reading.

Glenroy is where the money goes furthest. The median house price is roughly $862,000 against $1.18m in Pascoe Vale, and room rent only drops about $19 a week, so the same conversion works harder here. The trade is demand: 47 people searching against 23 rooms advertised is balanced rather than tight, and there are already 4 registered properties like yours. The pocket around View Street is visibly gentrifying, with subdivisions and good quality townhouses going up on the same street.

Further out and cheaper, and the low register count does look like a gap. But the area rating of 11 out of 100 puts it in the bottom band nationally, and it has the lowest home ownership and the only public housing of the three. You told us plainly that you want steady working tenants and not management headaches. Cheaper to buy does not always mean better to own, and this is the clearest example of that in the search so far.
