Fixed vs. adjustable: What is the lowest cost mortgage?
More concerning is refinancing several times into another 30-year mortgage. Mortgages are expensive because interest is charged over a long period of time and homeowners do not stay in their homes for 30 years. According to the National Association of Realtors®, the median duration of homeownership in the US is 13 years[1] as of 2018. So, the idea of locking in a low rate may be appealing but, the reality is that most Americans are starting their mortgages over again before they are even half way through paying it off.
