How does the council determine the value (in your rate notice) of a property and is there a relationship with market value. e.g. if a property had council value of 350k in 2008 and bought for 400k and in 2010 the new council value is 400k can you assume the market value to be at least 450K now ?
Is using council value this way a good way to re-value your property like for re-finance etc.
I have heard agents say that council values are much lower than the 'worth' of a property, and for buyers not to worry too much about it.
This may be most true after several years of strong growth and council values have not kept up with the market.
But I most certainly do not believe claims that properties always sell for way above council value correct.
I won't consider them infallible, but I'd consider council valuations a 'good value' purchase price. If you can buy at or near such a price the property is probably better than average value and yield (it's renovation potential might be poor, making this approach less suitable for the renovator though).
Supposing one did little but put in offers at council valuations and only bought when the vendor came down to near that price, you'd get a lot of rejections but would also end up with some great value purchases.
If one had a policy of researching and making one offer per week over 40 weeks of the year (near council valuation) and only one in 20 of those offers were accepted, that's still 2 property purchases per year (subject to finance and cashflow) which for 95%+ of property investors is a good result.
So in short, council valuation is one piece of information that could provide guidance on whether a property is good value or not. But if I as a buyer wouldn't pay much above council valuation, it would be rash for you as a seller to rely on your property being much more than that. A more realistic approach then would be to consider the council valuation as a fair (but probably conservative) estimate of value.
I think it varies between states but Victorian council valuations give both an unimproved (ie land) and an improved (ie house and land) figure.
