You can buy a home for as little as 1c!

Lowest price auctions - people register to bid (say $60) and they then try and bid the lowest unique price.

So you could get a house for 1c

The only thing you have to stipulate is that you have to sell 5000 registrations.
So they could pay 1c for a house worth $200,000 but you've sold $300,000 worth of registrations.
