Hi Stella
We have also purchased a house in Ofena through HAI.
The rates for the year were 59 euros per person, we used the accountant recommended by HAI this year due to time constraints but his charges were 300 euros, next year we will be doing it ourselves.
If you bought through HAI have you spoken to their 'Girl Friday' Francesca Palmy she is very good and reliable and totally trustworthy? As regards the utility bills the water and electricity were transferred to our names when we purchased the house but for the gas supply we had to meet with the Gas supply company at the council offices in Ofena to sign the paperwork and arrange to have a meter fitted which cost us 540 euros(standard charge).
