According to the Halifax index just out they are, but then we need to look carefully at the raw data to understand the true situation

The final Halifax index for 2009 has been released and it settles on a December 2009 average house price 5.6% above that of December 2008.

This is roughly in line with the figures from Nationwide which show a 5.9% rise.

It is easy from this to draw the conclusion that on average your house is worth about 6% more than a year ago.

That would be an ill-advised assumption at best and foolish at worst.
