Personalized Insights

4 insights based on your inputs

Consider Carefully

Break-even of 23 months is long. Make sure you'll stay in the home that long to benefit.

Significant Rate Drop

A 1.00% reduction is typically worth refinancing if you plan to stay 3+ years.

Extending Your Loan

Refinancing to 30 years extends your payoff. You'll pay more total interest even with lower rate.

Frequently Asked Questions

When should I refinance my mortgage?

Generally refinance when you can lower your rate by 0.5-1% or more, plan to stay in the home past your break-even point, have good credit (720+), and have at least 20% equity. Also consider refinancing to remove PMI, switch loan types, or access cash-out equity.

What is the break-even point?

The break-even point is when your monthly savings equal the closing costs paid. After this point, you start actually saving money. Calculate by dividing closing costs by monthly savings. If break-even is 24 months and you plan to stay 5+ years, refinancing makes sense.

What are typical refinance closing costs?

Closing costs typically range from 2-5% of the loan amount. This includes appraisal ($300-600), title insurance ($500-2000), origination fees (0.5-1%), recording fees, and other lender fees. Some lenders offer "no-closing-cost" refinancing with higher rates.

Should I do a cash-out refinance?

Cash-out refinancing lets you borrow against home equity for renovations, debt consolidation, or major expenses. Rates are slightly higher than regular refinance. Only do this for value-adding purposes, not lifestyle inflation. Remember you're increasing your debt and risk.

What is the difference between rate-and-term and cash-out refinance?

Rate-and-term refinancing changes your interest rate and/or loan term without borrowing more. Cash-out refinancing lets you borrow more than you owe and pocket the difference. Cash-out has higher rates and stricter requirements (usually max 80% LTV).
