The Mortgage Calculator Reality Check: What Banks Won't Tell You

Enter your loan amount, interest rate, and term. The calculator will show your monthly payment. But here's what it doesn't show: property taxes (1-2% of home value annually), homeowners insurance (,000-3,000/year), PMI if your down payment is under 20% (0.5-1% of loan), and HOA fees if applicable. The real monthly cost is often 25-40% higher than the calculator shows.

Tip 1: Always budget for the "real" payment, not just principal and interest. Tip 2: A 15-year mortgage has lower rates but higher payments — run both scenarios. Tip 3: Extra payments toward principal in the early years save massive interest. Tip 4: Don't trust the bank's "you can afford this" calculation — they want you to borrow more.

The biggest mistake: trusting the pre-approval amount. Just because a bank will lend you $400,000 doesn't mean you should borrow it. Another error: forgetting about maintenance. Budget 1% of home value per year for repairs. Finally, ignoring the opportunity cost — that down payment could be invested elsewhere.
