There is a frequently quoted expression “more money has been lost from indecision than was ever lost from making a bad decision.” Regardless of the extent of its accuracy, most people can recall when procrastination has cost them money. 
There are markets so short of inventory that buyers have become frustrated after losing bids for several homes and have decided to wait until more homes come on the market. In the meantime, the shortage of homes is driving the prices up more by the month.
There are buyers who can’t find what they want for the price they want to pay and think that waiting will somehow change things. In some cases, what they want just keeps moving farther and farther away from them.
The other dynamic in play is, of course, the mortgage rates. While they’ve remained low for several years, most experts agree that they’re going to rise; it’s just a matter of when. If you look at what positive increases in both of these would do, it becomes apparent that waiting will matter.
A $250,000 home purchased today on a FHA loan at 4% for 30 years will have a principal and interest payment of $1,151.76. If a buyer were to wait a year and the price increased 5% and the rate went up by 1%, the payment would increase by over $200 a month. In a seven year period, the increased payment alone would cost the buyer over $17,000.
Use the Cost of Waiting to Buy calculator to see how much it will matter based on the home you want to buy and what you think the prices and rates will do in the next year.
The Super Bowl and World Series determine the football and baseball champions. Since there can only be one champion, the other team loses the competition. In feudal times, a knight might champion for the king or a patriotic, romantic or religious cause.
