Remortgaging involves fees, ERCs, and rate comparisons that make the decision harder than it should be. Propty calculates the break-even point — the exact month when switching starts saving you money — so you can decide with confidence.
Portfolio Planning
Many portfolio landlords fund deposits by releasing equity from existing properties. Propty models the impact on your monthly payment and shows how much capital you can unlock at different loan-to-value ratios.
Most people remortgage when their fixed rate ends, as they'll revert to the lender's Standard Variable Rate (SVR) which is usually much higher. You can start the process 3-6 months before your deal expires. Our calculator shows whether switching early (with an ERC) or waiting saves more.
Typical costs include an arrangement fee (£0-£1,999), valuation fee (often free), legal fees (£300-£1,000, sometimes covered by the lender), and potentially an Early Repayment Charge if you're still in a fixed term. Our calculator includes all fees in the break-even analysis.
An ERC is a penalty for leaving your mortgage deal before the fixed or discounted period ends. It's usually a percentage of the outstanding balance — typically 1-5% — and often reduces each year. For example, 3% in year 1, 2% in year 2, 1% in year 3.
Yes — if your property has increased in value, you can borrow more than your current balance and take the difference as cash. Most lenders allow up to 75-85% LTV. This is common for portfolio investors using equity from one property to fund a deposit on the next.
Two-year fixes are typically cheaper but you'll need to remortgage again sooner (incurring fees). Five-year fixes cost slightly more but give you payment certainty and fewer transactions. If you think rates will fall further, a 2-year fix lets you switch sooner. Our calculator compares both options.
