Today I calculated the appreciation of my parents’ home in Potomac, Maryland which is a suburb of Washington DC in Montgomery County, one of the wealthiest counties in the United States.
They sold it for $439,000 on 1/27/1998. Zillow.com says today it is worth $863,654.
The buyers have owned it 19 years, 11 months and 25 days (7,299 days or 239.9669 months).
That means their home has appreciated $1,769.63 a month.
