GOOD IDEA FOR SOME?

I have read an idea on another site........

If you own a house in Spain and you have a UK mortgage on another property - borrow against the Spanish property with a Euro mortgage - lower rates than the UK and the Euros are now worth around 14% more pounds - transfer pounds to the UK and pay off/ reduce the UK sterling mortgage.

Just an idea someone had which I thought was cute and may be good for some others.........

PS Pound now 1.27 to the Euro (thats much better for some)
