If you can't afford much I think you'll have to wait for your dream home

Look for somewhere affordable for now so you can find your feet. Spend some time on here reading up on what can make for a good investment - maybe you can find somewhere that you will be able to sell on for a small profit later, to help you work your way up the ladder?
Are you in a stable job? Do you know where in the country / area you want to live? How much can you afford per month? Work out the answers to those questions and you will have an idea what your options are.
