When does it make sense to refinance?

Refinancing makes sense when: (1) Your new rate is at least 0.75–1% lower than current rate. (2) You plan to stay in the home longer than the break-even period (closing costs ÷ monthly savings). (3) Your credit score has improved significantly since your original loan. Typical break-even: 18–36 months. If you move before break-even, refinancing costs you money.

How does UK remortgaging work?

UK remortgaging is equivalent to US refinancing. UK borrowers typically remortgage every 2–5 years when their fixed-rate deal ends. If you don't remortgage, you move to the Standard Variable Rate (SVR), which is typically 2–3% higher. Early Repayment Charges (ERCs) apply during the fixed period — typically 1–5% of the outstanding balance. Best time to start: 3–6 months before your current deal ends.

What are typical refinance closing costs in the US?

US refinance closing costs are typically 2–5% of the loan amount. On a $300K loan: $6,000–$15,000. Main costs: origination fee (0.5–1%), appraisal ($300–$600), title insurance ($500–$2,000), recording fees, prepaid taxes/insurance. Some lenders offer 'no-closing-cost' refinances by rolling costs into the rate (higher rate) or loan balance.
