Hi Gary and Julie,
The provision of funds is calculated according to the price of the property. We completed lot of properties in Condado de Alhama (Naranjos, Jardines and La Isla) during 2008 and 2009 and our services included the inscription of the properties with the Land Registry (for clients with no mortgages) so maybe I can help you a little.
Polaris World usually sign the Deeds at the Notary's office in Torre Pacheco and it is quite expensive. Apart from that you will have to pay Land Registry's fees and Stamp Duty.
As I told you provision of funds depends on the price of the property but roughly:
Notary's fees + Land Registry's fees: 1.500€ - 1.700€
Stamp Duty: 1% of the price of the property.
And if the arrangements are made by a managements office (gestoria) you could be charged their fees: 200€ - 400€ depending on the company. In case that you apply for a mortgage your bank will inform you of the provision of funds because it will include Notary's fees, Land Registry's fees and taxes for the mortgage (not for subrogations).
Hope it helps.
