I'm starting to think about buying a house. I'll be buying it on my own. I have no clue whatsoever about mortgages so I need some general pointers. Some basics about me might help I guess. I'm 33, earn £30K excluding overtime (of which I can have as much as I like). I'll be looking to buy in the North East. How big a mortgage could I have, and how much will that cost me a month roughly? What are the different types of mortgages available and which would be best for me? TIA.
