I agree that the odds are stacked against single buyers. I bought on my own so I know how hard it is to get the deposit together, to house-hunt and to pay for the upkeep of one. The mortgage is only the start of the bills that never stop coming through the letterbox. As things stand for you, OP, you're going to find it hard to buy anything that isn't a shoebox or in an undesirable area. It's not nice to read that but it's the truth.
We'd all like to have an 80k job but they're not things that fall into anybody's lap. If you don't want to leave your existing job, is there anything you can do to enhance your position and move up the ladder? Can you upskill or do extra training courses, for example?
Other than that, all you can do is grit your teeth, make sacrifices and look at it as a short-term pain for a long-term gain.
