A Complete Guide to NatWest Second Home Mortgages

Buying a second home can be one of the most rewarding financial decisions you make — whether it’s a weekend bolthole, a place nearer work, or somewhere for family to stay. But unlike your first mortgage, arranging finance for a second property comes with a few more moving parts.

That’s where we step in. At Strive, we’re whole-of-market mortgage brokers. We’ll guide you through NatWest’s second home mortgage options, but we won’t stop there. Because we can access the full market — including exclusive rates you won’t find directly — we’ll help you see if NatWest really is the best fit, or if another lender might give you more flexibility.

Can I Get a Second Home Mortgage with NatWest?

Yes — NatWest is very much open to second home applications, and they’re one of the more appealing choices among high street banks.

One big advantage is the deposit requirement. Unlike many lenders who ask for at least 15–25%, NatWest will consider applications with just a 10% minimum deposit.

That doesn’t mean everyone will qualify at 90% LTV — your affordability still needs to check out. A 10% deposit is the starting point, but the loan you qualify for will ultimately depend on your income and commitments.

Key Criteria for NatWest Second Home Mortgages

When looking at NatWest as your lender for a second home, here are the essentials you need to keep in mind:

• Deposit: At least 10% (up to 90% loan-to-value), subject to affordability.
• Usage: The property can be used by you, a partner, or family. It could be a holiday base, a weekday work home, or somewhere for relatives.
• Affordability: You’ll need to prove you can comfortably manage this new mortgage alongside your existing commitments.

How Does NatWest Assess Affordability?

NatWest takes a practical approach to affordability. They don’t just add up your total borrowing and stop there. Instead, they look at:

• Your monthly mortgage payments (current and proposed).
• Your income and fixed commitments (loans, credit cards, childcare, etc.).
• How sustainable your overall budget looks once the new mortgage is factored in.

This approach can sometimes mean NatWest is more generous than lenders who focus purely on aggregate borrowing. But it’s not as simple as saying “4.5 or 5 times income” — the reality is shaped by your broader financial picture.

What Credit Score Do You Need with NatWest?

Like most high street lenders, NatWest doesn’t publish a fixed minimum credit score. But in practice, you’ll usually need a reasonable to good score to be accepted for a second home mortgage.

That means:

• A solid history of paying bills and credit on time.
• No serious recent defaults or county court judgments.
• A track record that shows you can handle borrowing responsibly.

If your credit history is more complex, it doesn’t necessarily rule you out, but it could mean NatWest isn’t the most suitable lender — that’s where a whole-of-market broker can help find alternatives.

Are NatWest a Good Choice for Second Home Mortgages?

They certainly can be. NatWest are a well-known, stable lender with clear policies and a good track record for second homes.

✅ Where they stand out:

• Lower minimum deposit (10% vs 15–25% elsewhere).
• Competitive rates aligned with their main residential deals.
• Fair affordability assessments based on monthly outgoings.

⚠️ Where they may be less ideal:

• If your affordability is already stretched — another lender might give more headroom.
• If you need very specialist criteria (e.g. unusual income, complex structures).

Stamp Duty on Second Homes

One extra cost that often catches people out is Stamp Duty Land Tax (SDLT).

For second homes, you’ll pay the usual stamp duty plus a 5% surcharge. This can be significant on higher-value properties, so always build it into your budget planning.

How Much Can I Borrow with NatWest?

There isn’t a simple one-size-fits-all answer. While NatWest may lend up to typical income multiples, the amount available will vary depending on your current borrowing and financial commitments.

Put simply: expect your existing mortgage and outgoings to reduce how much you can borrow for a second home.

Deposit Sources Accepted by NatWest

NatWest usually allows a second home deposit to come from:

• Savings
• Gifts from family
• Equity released from your current property (subject to affordability)

Should You Choose NatWest for Your Second Home?

If you’re looking for a second home mortgage with a lower deposit requirement and competitive rates, NatWest is well worth considering.
