Call the guys at JWS and see if they will give you discount if you group a few purchases together.
When it come's time to purchase your house, give me a buzz and ill come over have a beverage with you and tell you how much you can borrow and which bank product is best for you, then write your application to said bank/lender when you are ready. etc etc (i.e. i take the pain and stress out of buying a house)
