Housing
Calculate equity freed, monthly savings, and projected investment growth from downsizing your home.
Downsizing frees $0.00 in equity plus $6,000.00/year in reduced expenses. Invested at 7%, this grows to $609,985.50 over 30 years.
Freed equity + monthly savings invested over time

It depends on the price difference and your current mortgage. Selling a $500,000 home with a $200,000 mortgage and buying a $300,000 home outright could free roughly $170,000 (after 6% selling costs). This is a significant wealth-building catalyst.
Typical savings include lower property taxes ($100-300/month), reduced utilities ($50-150/month), less maintenance ($100-200/month), and potentially no mortgage payment. Total monthly savings of $500-$1,000+ are common.
If you have high-interest debt, pay that first. Otherwise, investing the freed equity in a diversified portfolio at 7% historical returns produces significant long-term growth — $200,000 grows to roughly $400,000 in 10 years.
Moving costs ($2,000-$10,000), selling costs (5-6% of sale price), buying costs (2-3% of purchase price), potential capital gains tax on profit over $250k/$500k exclusion, and emotional costs of leaving a home.
When your home is significantly larger than your needs (empty nesters), when you have substantial equity, when housing costs consume more than 30% of income, or when you are approaching retirement and want to convert illiquid equity to investable assets.
Calculate maximum and comfortable home-price ranges with DTI constraints, taxes, insurance, HOA, and down payment assumptions.
See your full monthly housing payment, principal vs interest, and how fast the loan balance falls over time.
See when buying actually pulls ahead of renting after monthly costs, equity buildup, and invested cash are all counted.
See whether a rent increase is still worth it once moving costs, deposits, and your new monthly baseline are all on the table.
