You can become frustrated making offers on properties that have multiple offers.  If you do not win the bidding war, your client does not get a home and you do not get anything.  The five top tips start with learning the most important thing about the situation: how many other offers are you competing with.  If there are a few, you offer a good price.  If there are many, many offers, you offer an amazing price.  Second, try to find out if there are any terms where you can win on something other than price. Third, before anyone else gets to the property, try to get it under contract to avoid the bidding war.  Fourth, consider an escalation clause to offer more than any other offer.  Last, if you lose, see if you can tie up the property with at back up offer.  For all the details, look at the article in Inman News.
