I think you need to check with professionals in the relevant country. In the UK, the word "bid" would suggest that the property was being sold by auction, but that is not how most properties are sold in the UK.
In the UK, "n offers have been received" (where n is a number) seems right (but I am not a professional). Buyers make "offers" to buy and name the price they are prepared to pay. The seller can accept any of the offers, not necessarily the one with the highest price. Offers to buy are normally made "subject to contract" and are not legally binding until a contract (written by a lawyer) has been signed and exchanged. http://hoa.org.uk/advice/guides-for-homeowners/i-am-buying/making-an-offer-and-haggling-over-the-price/
In an auction, the auctioneer chooses a price that he or she will accept, and buyers "bid" to accept that price. The auctioneer then raises the price until only one "bidder" is left. The "final bid" is a legally binding contract, even though you don't know, at the time when you make the bid, whether or not it will be the final one.
