I used this site when i was researching my first-step onto the property ladder, but I also found What Mortgage quite useful. It has a checklist type section in the middle that you can pull out and take with you when you look at houses etc, and also helps with things like what to ask your mortgage lender, broker or IFA.

Enjoy house hunting!
