I have lived in Wallan most of my life so I can probably help out with a few queries in this forum. My husband drives to work each day to St Kilda Road using the CityLink tool ways and it takes him just under an hour ( that is door to door ) - he can't believe it. I catch the VLine Train and it takes 45 minutes on the train and then obviously the time getting to and from the station. The train in Vline and is not has frequent as the Met but I think it's a pretty convenient service, it is so comfortable and safe. I have also lived in St Kilda and missed the Vline and I don't miss the packed Trams and Trains.
In my opinion Wallan does lack facilities and always has but with people comes investments and in the last couple of years it has started to explode, people just seen to be appearing. There is a new high school, police station, industrial zone, shopping centre and the council seems to be rezoning areas for business development zones. Give it a few years and I think it will have the facilities there will be to many people there, to many business opportunities.
There is a 4 lane highway that is about to be built that will go through the middle of Wallan, locals are annoyed and protesting but I think it will go ahead. At the risk of offending my neighbours I think it's a good thing. The main street has been neglected for years and this will improve it, basically make it look new.
I have just bought a home in Hidden Valley, its a Hidden secret, no-one seems to know about it. It has some of the most beautiful views in Victoria and does remind me of my trips to Tuscany ( you really do have to see it to believe it ) . My husband and I could not believe how cheap it was, nowhere an hour from Melbourne can you buy what we bought for what we paid in Hidden Valley.
The issue that we have found is that they are still releasing land in Hidden Valley so I don't think house prices are rising at a rapid rate, people buy and build and as I have already said no one seems to know it is there ( you can't really see it from the highway ) and people seem to think Wallan is hours from the city which is just not true. Saying that they are only permitted to sub-divide 900 blocks in this particular development and so a time will come in the next year or so when they can't release anymore land. You will still be able to get land in Wallan but Hidden Valley is very unique and land will no longer be available.
I also own an investment property in the area and have never had a problem renting it, if a tenant has left I have always been able to rent it within 2 weeks and have had a choice of long and short term tenants. The rental return isn't that high and pays for a mortgage that I took out years ago. If I was to buy another property in Wallan I would aim for a smaller house, something that you could rent out for 250 a week and be happy - I'm not sure about what will happen with house prices but I told think they will go up as much as some other areas around melbourne.
Anyway for what it's worth that is my two cents worth. Have a look at Hidden Valley the website is
