If the rate were to go up by ½%, the payment on a $275,000 mortgage would increase by $82.87 per month for the entire 30-year term. That would increase the cost of the home by $29,835.
Some people are purchasing the maximum home that they can qualify for. In that case, they cannot qualify for a higher payment and the only way to buy the same price home is to put more money down which may not be a possibility. The other alternative is to buy a lower price home which may not be in the same area or size which will involve some compromises.
The rate is not the only dynamic that affects buyers waiting to purchase. The home they want could sell to someone else. Prices could increase as new homes come on the market. The question that many buyers ask themselves when they become a victim of the consequences of delay is "What could we have spent the money on if we didn't have to make a higher payment?"
Mortgage rates are very attractive currently and within ½% of the all time low of 3.35% in December 2012. The highest rate was 18.45% in October 1981. Whether you're purchasing or refinancing, it may not be this low again.
