Private Mortgage Insurance (PMI) is required when your down payment is less than 20%. It protects the lender if you default, and typically costs 0.5–1.9% of the loan amount annually. Once you reach 20% equity (80% LTV), you can usually request removal.

Extra principal payments reduce your loan balance faster, which means less interest accumulates. On a 30-year mortgage, even $100/month extra can save tens of thousands in interest and shorten your payoff by several years.

The full monthly housing cost includes principal & interest (the core payment), property tax (1/12 of annual), homeowner's insurance (1/12 of annual), PMI (if down payment < 20%), and HOA fees (if applicable).

Higher interest rates increase the monthly payment significantly. A 1% rate increase on a $300,000 loan can add $250–300/month. Factors affecting your rate include credit score, market conditions, loan type (FRM vs ARM), and loan term.

Fixed-rate mortgages (FRM) have the same interest rate for the entire loan term, so your payment never changes. Adjustable-rate mortgages (ARM) start with a lower rate but adjust periodically (usually annually), which can increase your payment.

A higher down payment lowers monthly payment and total interest. Many buyers target 20% to avoid PMI, but 3-10% options exist depending on loan program and eligibility.

APR is better for comparing total borrowing cost because it includes interest plus fees. Use APR when evaluating lender offers with different fee structures.

Yes. Refinancing replaces your current loan with a new one. It can reduce payment or term, but closing costs and break-even time should be evaluated before proceeding.

It is a payment timeline showing how much of each payment goes to principal and interest, plus remaining balance after each period.

Choose a shorter term, add extra principal payments, improve credit for better rates, and refinance strategically when economics are favorable.
