You are welcome, i glad you thought it of some use.
I have no knowledge of Gib, but have been there several times. I am guessing that the very small land area and unique characteristics of being a British outpost? and having special tax status, indeed does make it different. I do know that for example it is now a very attractive home to IT and internet based businesses from all over the world.
Actually property profs would probably use a nett figure of closer to 7 to 8% and remember there is an important difference between gross and nett. Buy carefully and think always of having to resell, imagine yourself in the sellers shoes when looking at the good and bad bits. Never ever let your emotions take over and never overpay. Other halfs have a tendancy to both - oh dear i shall be in trouble now lol!
Good luck
