How does it help with mortgage points calculations?

The skill calculates the 'breakeven point' by comparing the upfront cost of points against monthly interest savings to determine if buying down the rate is financially beneficial.

Can I use this to see how much house I can afford?

Absolutely. By analyzing your income, existing debt (DTI), and available down payment (LTV), the skill provides a realistic assessment of loan qualification and affordability.

Can this skill compare 15-year and 30-year mortgages?

Yes, it provides detailed comparisons including monthly payment differences, total interest costs, and the speed of equity accumulation for both terms.

Does the skill handle HELOC and home equity analysis?

Yes, it evaluates Home Equity Lines of Credit, including Combined Loan-to-Value (CLTV) ratios and the transition from draw periods to repayment periods.
