Learning the reason why can help you get the price you want and help the seller get what they want: a timely sale.
When given the opportunity to meet with sellers, ask them why they are selling. The reason could be anything, such as a job change to a new location or financial problems. If you can solve their problem, whether it is cash related or time related, do so.

If you can make an offer, even a low one, that gives them cash in a short time, they are more likely to accept.
