A $500k home with 20% down means a $400,000 loan. At current rates, your monthly payment — including tax and insurance — is likely higher than most buyers expect.

In year 1, 87% of your payment goes to interest and only 13% reduces your balance.
At this rate, it takes until year 21 before more than half your payment builds equity.
On your $400,000 loan, you'll pay $558,036 in interest — 1.4x what you originally borrowed.
Switching to a 15-year term would cut your interest in half — but raise your monthly payment.

If the payment feels high — a lower home price or larger down payment will move the needle more than a slightly better rate.
If you're close to 20% down — getting there eliminates PMI and meaningfully reduces your monthly cost.
If you're comparing loan terms — a 15-year mortgage costs more monthly but saves significantly on total interest.
On a $400k loan at 7% for 30 years, principal and interest alone comes to roughly $2,661/month. That number climbs fast if your rate is higher or your term is shorter.
Property tax (~1.1%) and homeowner's insurance add $500–$700/month on a $500k home depending on your state. Your true all-in payment is often $400–$600 more than P&I alone.
Putting $100k down keeps your loan-to-value at 80%, which eliminates PMI entirely. That saves $150–$250/month compared to a 10% down scenario.
