How a Home Purchase Changes Your Retirement Plan

Start with the full cost of ownership

Mortgage principal and interest are only part of the budget. Include property taxes, insurance, HOA fees, mortgage insurance if applicable, maintenance and utilities. The Consumer Financial Protection Bureau’s homebuying guidance explains why both upfront cash and ongoing ownership costs matter.

Use actual lender, insurance and tax estimates when available. Avoid applying a single monthly payment from a listing to a decades-long plan. Fixed-rate mortgage principal and interest may stay level while property taxes, insurance and repairs change.

Example: $70,000 upfront and $1,600 more each month

Fictional example · all amounts are at the time of the move

Jordan is comparing staying in the current home with moving now. The new home requires a $150,000 down payment and $20,000 of buying costs. Selling the existing home releases $100,000 after the old loan, selling costs and any sale tax.

The move adds $19,200 per year at these starting costs. Over ten years with no cost increases, that is $192,000 of additional outflow, plus the $70,000 upfront. Neither number includes the investment growth that money might otherwise earn.

These are cash-flow differences, not a calculation of lost net worth. Some principal payments build equity, the home’s value may change, and selling later has its own costs. The example holds maintenance and utilities unchanged to isolate the comparison; a larger home may cost more in both categories. No tax deduction, investment return or future sale value is assumed.

Enter the move without counting housing twice

1. Build and save a baseline with your current housing costs in everyday spending. Under Manage scenarios, duplicate it for the move.
2. Open Life events → Add life event → Buy or move home. Choose your age at the purchase and check the dollar basis. Future purchase-year estimates and today’s-dollar estimates are different.
3. Enter $170,000 under down payment and buying costs for this example. Turn on Selling your current home and enter $100,000 in net proceeds separately. Do not subtract the proceeds twice.
4. Enter the full new mortgage payment of $3,000, not just the $1,000 increase. Keep Replace current housing costs selected for a move. A linked budget supplies the old housing payment; otherwise identify the current payment already in your budget.
5. In More home details, update property costs: $500 of current combined monthly costs and $1,100 split across new property tax, insurance and HOA. Keep maintenance and utilities in your everyday spending and adjust them if needed.
6. Set mortgage timing and review upfront funding. If the old mortgage is a separate loan event, link it so it ends at the move. Do not add a second event for the new mortgage.

For this illustration the purchase happens now. For a future move, the event’s dollar basis affects the new amounts; the current housing costs you identify are in today’s dollars. Review the move summary to confirm the intended replacement and funding need.

Look beyond the ending portfolio balance

Compare available savings immediately after buying, annual saving while working, brokerage at retirement and the first funding gap. If a gap appears, try a smaller purchase, a later move or a different retirement date—changing one thing at a time.

Optional home-equity tracking adds the home and mortgage to net worth. It does not make the equity available for everyday spending. Upfront home funding can also use cash otherwise held as a reserve, so check that your chosen funding order leaves the cushion you intend.

Keep the same return path for “Stay” and “Move” before testing weaker markets. A different random path can obscure the effect of the housing choice. The calculator illustrates a plan; it does not determine loan eligibility, quote mortgage terms or fully calculate the tax consequences of a sale.
