What you might want to do is look for somewhere that is available for rent with an option to buy. This would then give you the enjoyment of the place you want to buy, plus time to save the money. You would not be committed to buy, but you would have the right to do so at a price agreed now, and at any time over the next X months/ years, whatever is agreed between you and seller. The seller may even be willing to help you finance the purchase, but finding a seller willing to do that on the one property you want to buy, may be tough.
The time to try and buy without money is when house prices are appreciating rapidly, not the reverse. You need cash in this market, otherwise my advice is don't even attempt it - stay away until you do.
