The median home price in February, 2019 was approximately $315,000 (source: https://www.census.gov/constructionrs/pdf/uspricemon.pdf). Assume that a family is purchasing a typical house by making a $35,000 down payment and then financing a $280,000 mortgage at an annual interest rate of 4.50% (a typical rate for a 30-year loan in early 2019).
