Stay in my house vs. rent

Run the numbers on the choice that locks up a huge chunk of retirement money. This calculator counts home equity growth, selling costs, and what else you could do with the money if it weren't tied to a house.

Your house

Rule of thumb: 1% of home value per year.

The rental

First month, deposit, moving truck, etc.

Assumptions

Annual. Historical average is roughly 3–4%.

What the freed-up equity could earn after selling.

Realtor commission + closing costs.

Monthly cash flow

Stay

$2,120/mo

Mortgage, tax, insurance, HOA, upkeep, utilities

Rent

$2,075/mo

Rent, renter's insurance, utilities

-$45/mo

Renting costs less each month.

After 10 years

If you stay

$321,964

Estimated home equity after selling costs

  • Future home value$470,371
  • Remaining mortgage$120,185
  • Selling costs$28,222
If you rent

$258,775

Invested proceeds plus monthly difference

  • Net proceeds from sale today$149,000
  • Move-in cost$3,600
  • Total rent paid$249,000
Net-worth differenceStaying ahead by $63,189

This is the difference in liquid wealth after 10 years, assuming you sell the house at the end of the stay scenario. It ignores taxes, emotional value of owning, and the risk of rent rising faster than assumptions.

Break-even rent

$2,595/mo

If you can rent for about this much or less, the economics of leaving start to look competitive — counting interest, taxes, upkeep, and the opportunity cost of your equity.

The bottom line

Based on these numbers, staying put builds more wealth over 10 years. The forced savings of the mortgage and home appreciation are outpacing the rental alternative right now.

Things this calculator can't count

  • Peace of mind. Not having a landlord, a lease renewal, or a sudden move has real value that doesn't show up in dollars.
  • Taxes. Mortgage interest and property tax deductions vary by state and income. Capital gains exclusions may apply when you sell a primary residence.
  • Rent increases. This model assumes rent stays flat. In many markets, rents rise faster than ownership costs.
  • Maintenance surprises. A roof, HVAC, or foundation problem can wipe out several years of expected savings in a house.
