Understanding the Financials

The Buy Side

•Mortgage Interest & Principal (Forced savings)
•Property Taxes & Homeowners Insurance
•Maintenance (typically 1% of home value/year)
•Asset Appreciation & Tax Benefits

The Rent Side

•Monthly Rent (100% expense, subject to inflation)
•Renters Insurance
•Opportunity Cost (Investing down payment in stocks)
•Zero exposure to housing market fluctuations

1. How Appreciation Builds Wealth

Home appreciation works as a leveraged return. If you put 20% down on a $500,000 home ($100,000) and the home appreciates by 3.5% in year one, the home's value increases by $17,500. That is a 17.5% return on your actual cash invested. Over 30 years, compounding appreciation is the single largest driver of a homeowner's net worth.

2. The Impact of Selling Costs

When you buy a home, you start with a negative net wealth position relative to renting. This is because selling a home typically costs about 6% of the home's value in real estate agent commissions and title fees. If you were to buy a home and sell it the next day, you would lose thousands of dollars. The calculator factors this in, which is why the "Buying Wealth" line starts lower than the "Renting Wealth" line.

3. Why the First 5 Years Favor the Renter

Standard 30-year fixed mortgages are front-loaded with interest. In the early years, the vast majority of your monthly payment goes directly to the bank, with very little paying down the principal (your equity). Combined with closing costs, this means renting and investing your down payment is almost always mathematically superior if your time horizon is less than 5 to 7 years.
