Property transfer taxes in Seville

Hi,

I have recently heard a few horror stories about people who have paid property transfer taxes on a place, only to be hit with astronomical tax demands a few months/years down the line. The reason for this being that the property market has pretty much collapsed since the original valuations (valor catastral) were made.

I personally know of a couple of people this has happened to, but not regarding huge amounts of money (1-2,000 euros), but I've read about people losing much more. 

I'm currently to buy a place in Sevilla which had its valor catastral made in 2001, which was then valued at around E30,000 more than the current asking price! So I suspect that I might have some problems later down the line if I do go through with the purchase. Has anyone bought something in Sevilla over the last year or two who can share their experiences?

I believe the values are assessed by using a multiplier and the square metres.   That multiplier varies according to the  town, the part of the town  and the ‘quality' of the property.   A notary can access the web page and see the value the tax office will use, but I am not sure if they will tell you if you ask.  A gestor, abogado etc.  should be able to do so too.

Exactly, the tax value of the property is made up of multiplying the cadastral value by a local public index
