Worst case scenario? It's probably closer to this: buy way more house than you need and can sensibly afford. Buy heavily leveraged at market peak. Housing market tumbles. Have a bit of bad luck and lose your job and your income. Be in a position where you can't keep up with mortgage repayments and be forced to sell when the market price for the house is less than the amount of debt you still owe the bank... Or even grimmer: as above, but start renovations before the market crashes and losing your job. Discover there are major structural problems so it costs 3x more than expected to put the house back into a sellable state. Then, before construction is finished, be forced to sell an unfinished house with negative equity....
