Hi Bun.
Well If I were you I would pull out of the contract now (*). Don't buy off-plan as an investment now or you'll lose alot of money.
On the other hand If you are buying O-P as a home then carry on.
(*)The reservation 3.000 euros is a non-refundable deposit. If you pull-out now you lose the 3.000 euros and you cannot in any way reclaim it back.
Well of course Bun, once you pay 3.000 euros or 30% downpayment before completion you are LEGALLY entitled to PESTER/MOLEST your lawyer until he obtains on your behalf said bank guarantee or insurance policy. It is outr job to ensure this. Accept no excuses whatsoever, the lawyer MUST obtain this guaranteee.
The bank guarantee is only given a few months after you've paid the 30%, never before. It guarantees past payments you've done, not future payments and only for the amount of the guarantee.
DEMAND from your lawyer a faxed copy of said guarantee, it is vital.
If he doesn't obtain the guarantee for you I guarantee you 100% he works for the developer and not for you.
Water, electricity etc.. all that comes into play after the Licencia de Primera Ocupación (Licence of First Dwelling) shortly before completion, in your case probably in year 2007 or later.
You paid a lawyer 2% ?? I wish I had more clients like you.

seriously, that is not right,the legal standard fee is 1% whether if the plot is rustic or urban. If you pay more than 1% renegotiate or wheel and deel with your lawyer saying you'llgo with a more competitive one.
If you have any further queries Bun just post them in this forum, I'll reply.
