Are You Missing Out on Bigger Equity Gains? - 6/10/2026

Many homeowners are holding back from moving because they don't want to give up their low mortgage rate. But in doing so, they may be missing out on long-term equity gains that far outweigh the interest savings. Let's walk through an example.

The Current Situation

Imagine you own a $400,000 home with a $200,000 mortgage at 4%, with 24 years left. On the surface, it feels smart to stay put...you've got a great rate and manageable payments. But what happens if you want to upgrade to a $600,000 home and you keep waiting?

Selling & Buying

Selling your current home at $400,000 and accounting for about 7.5% in selling costs leaves you with around $170,000 in equity. Apply that equity toward your next purchase, and your new loan on a $600,000 home would be roughly $430,000.

At today's 6.25% for 30 years, your principal and interest would be higher than your current payment. But here's the bigger picture:

Equity Growth on the New Home

  • Appreciation: At an average of 4% annual growth, a $600,000 home could rise to about $730,000 in just 5 years, an increase of $130,000.
  • Amortization: Over those 5 years, you'd also pay down about $50,000 in principal on the new loan.
  • Combined Equity Gain: That's about $180,000 in new equity, more than you'd ever gain by staying put in your current $400,000 home.

The Cost of Waiting

If you don't move, your $400,000 home will still appreciate, but at 4% annually, that's only about $87,000 in five years. Plus, your mortgage paydown would be much less since your loan balance is lower and further into amortization.

By staying put, you're essentially trading short-term savings for long-term opportunity. The gap in wealth-building between the $400,000 home and the $600,000 home widens more every year.

The Smarter Move

Yes, you'll give up a low rate—but you'll gain the bigger advantage: a larger asset that appreciates more in dollar terms and builds more equity through amortization. Over time, appreciation on a higher-value home creates significantly more wealth than clinging to a lower-rate mortgage on a smaller property.

Don't let the fear of losing a low interest rate stop you from moving up. By investing your equity into a larger home today, you benefit from greater appreciation, stronger amortization, and the long-term financial rewards of owning a more valuable property.
