currency.transferFrom(msg.sender, property.ownerOf(tokenId_), price_);

If price_ is higher than current price, shouldn't we refund sender the part above?

[guoliu]

Since the bid price needs to be higher than the asking price, price_ is always higher than the current price. I think we can automatically set the price to the bid price (TODO) instead of refunding the sender. So price increases with bids, making it more reflective of market competitiveness.
