How Much Can I Remortgage My Property For?

Published: 08/08/2025 By Cavender Estate Agent

Introduction

It is a common question in the current climate for many homeowners across the UK to understand how much you can remortgage your property for. Many need a cash injection for help with their home improvements, consolidating their debts, or with the goal to secure a more competitive interest rate to free up cash to spend elsewhere. This guide explains the exact factors that many lenders use, along with the practical methods to estimate your maximum remortgage amount, real-world scenarios, what fees to expect, our tips for boosting your borrowing power and why Cavender Estate Agent can potentially help.

1. Key Factors Determining Your Maximum Remortgage Amount

Your maximum remortgage sum reflects a blend of four primary considerations:

1. Outstanding Mortgage Balance and Equity
   
• Equity equals current market value minus any outstanding balance.
  
  
• You can typically borrow up to a percentage of your property’s value (loan-to-value or LTV).
  
  
2. Loan-to-Value (LTV) Thresholds
   
• High-street lenders may permit up to 95% LTV for straightforward rate-switch remortgages, subject to criteria.
  
  
• Specialist or buy-to-let remortgages often cap at 65–75% LTV.
  
  
3. Affordability Assessments
   
• Lenders review income, outgoings, credit history and future interest-rate scenarios.
  
  
• A higher income or cleaner credit record can raise your borrowing ceiling.
  
  
4. Purpose of Remortgage
   
• Standard remortgages (rate switches) follow one set of rules; borrowing extra for extensions or buy-to-let attracts stricter checks.
  
  

2. How to Estimate Your Remortgage Borrowing Capacity

While we do not not offer our own remortgage calculator, you can combine two complementary approaches for an accurate estimate:

A. Lender Decision-in-Principle (DIP) or Agreement-in-Principle (AIP)

• Submit basic details—current balance, income, outgoings and credit history—to a lender or broker.
  
  
• Receive an instant indication of your maximum loan amount with no impact on your credit score.
  
  
• Use this figure to shortlist remortgage deals.
  
  

B. Manual Estimate Using a High-Street LTV Benchmark

1. Find your property’s current market value via estate-agent valuations or online tools.
   
   
2. Subtract your outstanding balance to calculate existing equity.
   
   
3. Apply the lender’s maximum LTV percentage to the property value.
   
   
4. If borrowing extra, adjust for affordability: subtract a buffer for potential rate rises (e.g., 2%).
   
   

For example, a £300,000 home with a £120,000 outstanding balance gives £180,000 equity. A 90% LTV cap implies borrowing up to £270,000. After subtracting your balance, you could release up to £150,000 for other purposes, subject to affordability.

We do however offer an Affordability Calculator for buyers along with our Stamp Duty Calculator for those seeking such assistance.

3. Scenario-Based Examples

Scenario	Property Value	Outstanding Balance	LTV Cap (%)	Maximum Loan Amount	Funds Available
Standard Remortgage	£300,000	£120,000	95	£285,000	£165,000
Home Extension Funding	£350,000	£120,000	90	£315,000	£195,000
Buy-to-Let Investment	£250,000	£150,000	70	£175,000	£25,000
Debt Consolidation	£300,000	£100,000	85	£255,000	£155,000

• Standard Remortgage assumes a simple rate switch up to 95% LTV.
  
  
• Home Extension Funding treats the property as worth more post-works but applies a 90% cap for additional borrowing.
  
  
• Buy-to-Let Investment typically allows lower LTV (65–75%) and stricter income stress tests.
  
  
• Debt Consolidation often attracts a mid-LTV cap (80–85%) and may include higher interest.
  
  

These figures illustrate theoretical limits. Cavender Estate Agent helps verify local valuation accuracy and advises on specific lender policies.

4. Understanding Remortgage Costs & Fees

A comprehensive budget must include both product costs and associated professional fees:

Cost Type	Typical Range	Charged By	Cavender’s Support
Product Fee	£0 – £999	Lender	Comparison of fee-free vs fee-bearing deals
Valuation Fee	£150 – £1,500	Lender (if not covered)	Negotiation of free valuations on select deals
Legal Fees	£500 – £1,000	Conveyancer	Recommendation of trusted local solicitors
Early Repayment Charge (ERC)	1% – 5% of outstanding balance	Current lender	Tollgate analysis of ERC timing and costs
Broker Fee	£0 – £500	Mortgage advisor	Partnership with L&C for fee-free advice

• Product Fee: upfront charge for the mortgage offer; sometimes offset by lower rates.
  
  
• Valuation Fee: covers lender’s assessment of property value; often waived by promotional offers.
  
  
• Legal Fees: for conveyancing work; we can introduce reliable local solicitors.
  
  
• ERC: penalty for leaving a fixed-rate deal early; check your mortgage contract carefully.
  
  
• Broker Fee: avoidable  options are available.
  
  

We coordinate our activities with lenders to secure cashback offers, legal-fee waivers or valuation incentives wherever possible, reducing your overall cost.

5. Tips to Maximise Your Borrowing Power

• Improve Your Credit Profile
  
  
• Correct errors on your credit report before applying.
  
  
• Keep existing credit accounts open and avoid multiple credit applications.
  
  
• Reduce Existing Balance
  
  
• Overpay your current mortgage where permitted.
  
  
• Lower your LTV to access more competitive rates.
  
  
• Stabilise Your Income and Outgoings
  
  
• Maintain continuous employment and clear any outstanding debts.
  
  
• Prepare documentation: payslips, bank statements and proof of bonuses or overtime.
  
  
• Consider Term Length
  
  
• Extending the mortgage term can lower monthly payments and support higher borrowing.
  
  
• Shortening the term can reduce total interest but raises monthly commitments.
  
  
• Shop Across Lenders
  
  
• Use our’ network to compare high-street, specialist and buy-to-let remortgage products.
  
  
• Balance interest rate savings against any product fees or arrangement charges.
