The $100K Income Equity Strategy Options
10-year equity outcomes by mortgage strategy — $420K home, 6.5%, 4% appreciation
| Strategy | Home Price | Down Payment | Monthly Cost | Year 10 Equity |
|---|---|---|---|---|
| 30-yr, 10% down | $420,000 | $42,000 | $2,620 | $218,000 |
| 30-yr, 20% down | $420,000 | $84,000 | $2,349 | $228,000 |
| 15-yr, 20% down | $420,000 | $84,000 | $3,060 | $310,000 |
| 30-yr, 10% down + $400 extra | $420,000 | $42,000 | $3,020 | $255,000 |
A 15-year mortgage on a $336,000 loan (80% of $420,000 with 20% down) at 6.0% costs $2,838/month. At year 10, the remaining balance is only $167,000 vs. $295,000 on a 30-year — $128,000 more equity through faster paydown alone. The tradeoff: $489 more per month. For $100K earners who can manage the payment, the 15-year often makes sense.
The Cash-Out Refi Timing at $100K Income
At $100K income, a strategic cash-out refinance at year 7–10 (when equity has built substantially) can fund a rental property down payment, investment, or home improvement without depleting savings. Example: $420,000 home with $218,000 equity at year 10. Cash-out refi at 75% LTV allows borrowing $315,000 — paying off existing $202,000 balance and extracting $113,000 in cash for investment, all while maintaining equity.
