I've been to England and I like it but I wouldn't want to live or work their although I could since I'm a British citizen. I actually have plans with a friend to go back-packing through Europe but that's in the far future atm.

Well if you apply for the WHP visa you will have the option of staying for a few years. I don't know when the application date for that visa is, but follow the link I gave you earlier in the thread and you'll find all the information there.
I'm not sure if you'll find a "more stable higher paying job" here. Have a read of some other threads regarding the credit crunch and some hard times people are experiencing over here. I don't want to burst your bubble, but just read them and be aware that the job you want may not be that high paying or that stable. A number of members on here have stated that foreign workers on temporary work permits are the first to be "let go." I cannot comment on the particular job you are interested in though as I have no idea about real estate! Maybe a memeber with experience there will be along soon to let you know about exams/courses/qualifications etc that you need.
It's good that you are doing your research and asking questions. You may not get all the answers you want, but it will help in the long run.
