What do you mean by "just finished" ? If you have just made the final payment it can take up to 6 months for the formalities to be completed and the fianl completion certificate to be issued. Many firms do this within a few weeks to 2 months, but some take longer.
My opinions are merely that .. opinions based on experience. Always seek professional advice.
