Down Payment Invested vs Tied Up in Home

A **down payment in a home** builds equity but is illiquid. **Investing that lump sum** while renting can outpace appreciation if markets cooperate—but you still pay rent with no forced savings.

Step by step

1. Set opportunity cost %

Use expected portfolio return on the down payment foregone.

2. Model rent growth

Rent hikes erode the invest-and-rent strategy over 7-10 years.

3. Add closing and selling

Buying has friction costs on both ends of ownership.

Invested down payment vs home

Breakeven depends on rent, appreciation, and after-tax invest returns.

  • Invest while renting: Liquid; market risk; no maintenance or property tax.
  • Buy with down payment: Leveraged housing exposure; forced savings; illiquid.

Common mistakes

  • Ignoring rent inflation
  • Assuming home prices always beat stocks

FAQ

Should opportunity cost be stock returns?

Use a conservative after-tax return you would actually hold.
