Many might disagree, but I think, we should not lose our deposit, if a sale of property didn't go through due to an unsuccessful mortgage. Every Real Estate agent request us to put an "unconditional offer", and their reasoning is that they have to find another buyer or change the Auction date. So cost of changing the Auction date is around $100,000 ( these days a house cost one million)
BTW, I am not a risk taker, so that's why I am still hunting for a house, just don't want to lose all my savings and I am refusing to put an unconditional offer.
If it is 1% of the property that would be at least ok.
*losing, lose, loser.
Just get all of your finances and pre-approved limits sorted before you go to purchase.
