How to Use This Buy Now vs. Wait Calculator
Enter your target home price, current mortgage rate, monthly rent, and your expectations for price and rate changes. The calculator instantly shows you the cost of buying now versus waiting 1 or 2 years.
Quick Calculator
Enter the Current Home Price, Current Mortgage Rate, and your Monthly Rent. Set your Down Payment percentage, Expected Annual Price Appreciation, and Expected Rate Change per Year (positive if you think rates will rise, negative if you expect them to fall). Results show monthly payment under each scenario, rent paid while waiting, and 5-year home value projections.
Advanced: Price Scenarios, Rate Scenarios, Rent Wasted
Price Scenarios shows how much more you'd pay for the home at 0%, 3%, 5%, and 7% annual appreciation over 1, 2, and 3 years. Rate Scenarios shows how different rate changes combine with price appreciation to change your monthly payment. Rent Wasted calculates the total financial cost of waiting including rent paid, price increases, and higher permanent payment.
Pro: Full Financial Model, Historical Analysis, Decision Matrix
Full Financial Model runs a year-by-year comparison of buyer equity versus renter portfolio wealth, accounting for home appreciation, debt paydown, rent paid, and investment returns on the down payment. Historical Analysis shows what happened to people who waited in 2012, 2019, and 2021. Decision Matrix maps the four key market scenarios (prices up/down × rates up/down) to clear recommendations.
Buy Now vs. Wait Formula
where r = annual rate / 12, n = 360 months (30 year)
Price if Wait = Current Price × (1 + Appreciation%)^Years
Loan if Wait = New Price × (1 − Down Payment%)
Cost of Waiting 1 Year:
= Rent Paid (12 × monthly rent)
+ Price Increase (new price − current price)
+ Higher Payments (extra $/mo × 12 months × remaining loan years)
Buyer Equity (Year N):
= Home Value at Year N − Remaining Loan Balance
Renter Wealth (Year N):
= Down Payment × (1 + invest rate)^N + monthly savings invested
The buy now vs. wait decision is fundamentally a question about the relative cost of your two options over a given time horizon. It's not just about mortgage payments — it's about total wealth position after accounting for equity, rent, and investment returns.
Example: Buying Now vs. Waiting 1 Year in Denver, CO
Marcus is deciding between buying now and waiting a year
| Current Home Price | $480,000 |
| Current Rate | 6.75% (30-year fixed) |
| Down Payment (20%) | $96,000 |
| Current Monthly P&I | $2,490 |
| Monthly Rent if Waiting | $2,300 |
| If he waits 1 year (4% appreciation, rates flat): | |
| New Home Price | $499,200 |
| New Monthly P&I | $2,589 |
| Extra/month (forever) | +$99/month |
| Rent Paid While Waiting | $27,600 |
| Price Increase | +$19,200 |
| Total Cost of Waiting 1 Year | ~$46,800 |
Marcus chose to buy now. The $46,800 cost of waiting exceeds his entire annual salary contribution to retirement. Even if the market softens slightly, he's unlikely to make that back in price reduction — and his rent would have continued climbing anyway.
