Your Home Finance
A second home is priced as a second home — not as another main residence.
Higher deposits, surcharge Stamp Duty and a thinner lender panel come as standard. How the property will genuinely be used decides the structure, and the structure decides the cost.

How your case is assessed
How lenders assess a second home
A second-home mortgage is residential lending on a property you won't live in full time. Lenders treat that as higher risk, and the tax position sits on top of it.
Affordability across both mortgages
Your existing mortgage payment is treated as a committed outgoing and assessed in full alongside the new one. No rental income is assumed on a genuine second home, so the whole cost of both properties has to be supported by your income.
Deposit and loan-to-value
Expect a larger deposit than on a main residence — commonly 20–25% and sometimes more, particularly on rural, coastal or non-standard properties. Deposits raised by remortgaging your main home change the assessment on both.
Stamp Duty surcharge and ongoing tax
Additional property purchases attract a surcharge on top of standard Stamp Duty rates, and the equivalents in Scotland and Wales work similarly. Council tax premiums on second homes now apply in many areas, and there is no main-residence relief on any eventual gain.
Intended use — and being straight about it
A genuine second home, a holiday let and a buy-to-let are three different products with different lenders, criteria and tax treatments. Declaring one and doing another breaches the mortgage conditions, so the honest answer has to come first.
You can't judge second-home affordability from a rate table — we model both properties, the surcharge and the running costs before any hard search.
Specialist insight
Not every second-property purchase is the same product
Minimum deposit · both mortgages tight · remote or non-standard property
Higher challenge
Short panel · surcharge and running costs squeeze affordability · lenders question whether the property can be sold easily if circumstances change.
Strong equity · clear surplus income · standard property, honest use
More lender choice
Broader panel and mainstream pricing · both payments comfortably supported · structure matched to how the property will actually be used.

“People arrive having chosen the cottage. The conversation that actually matters is whether it's a second home, a holiday let or a buy-to-let — because that single answer changes the lender, the deposit and the tax.”

Lived experience
Mistakes we repeatedly see
Not theory — the patterns that keep making second properties more expensive than expected.
Budgeting the deposit but not the surcharge
The additional property Stamp Duty surcharge on a mid-priced second home runs well into five figures. Buyers who have carefully saved a deposit are frequently blindsided by a tax bill that lands on the same day.
Taking a second-home mortgage and then letting it
Letting a property held on a second-home mortgage — even occasionally on a holiday platform — usually breaches the conditions. If letting is part of the plan, a holiday let or buy-to-let product is the honest and safer structure.
Assuming rental income will support the borrowing
Second-home lenders take no account of potential letting income. If the numbers only work with rent, you need a different product entirely — and that product tests the rent rather than your salary.
Ignoring the running cost of two properties
Two sets of insurance, utilities, maintenance, and increasingly a council tax premium on second homes. The mortgage is often the predictable part; it's the standing costs that erode the enjoyment.
Real client scenarios
Real second property journeys
Based on genuine cases we've helped with. Personal details have been changed to protect privacy.
Holiday let, not a second home
- Coastal cottage
- Letting intended
- Product changed
- Rent assessed
Situation
A couple buying a coastal cottage for family use, intending to let it for perhaps twenty weeks a year to help cover the costs.
Challenge
They had applied for a second-home mortgage, which would have prohibited the letting they were already planning — and their affordability was tight without any rental income counted.
What changed
We moved the case to a holiday-let lender that assesses seasonal rental income across low, mid and high season, and modelled the surcharge Stamp Duty into the deposit plan.
Outcome
Purchased on the correct product with letting permitted, and the rental income supporting the assessment rather than breaching the terms.
Why it worked
The plan hadn't changed — the product had. Getting the structure right at the start avoided a breach they didn't know they were heading for.
Advised to reduce the budget, not the ambition
- Two mortgages modelled
- Surcharge quantified
- Budget revised
- Bought comfortably
Situation
Homeowners with a substantial main residence mortgage wanting a second property within a couple of hours' drive.
Challenge
At their original budget, both mortgage payments plus the surcharge and running costs left almost no surplus — affordable on paper and uncomfortable in practice.
What changed
We modelled both mortgages together, quantified the surcharge and annual running costs, and showed the figure at which the second property stopped being a strain.
Outcome
They bought a smaller property in the same area with meaningful monthly headroom, and no reliance on letting it.
Why it worked
Nothing about the case was difficult to place. The advice worth paying for was the number, not the lender.

Before you enquire
What we'll ask you on the first call
Straightforward questions — no hard credit search at this stage.
- Your current mortgage balance, rate and monthly payment on your main home
- How the second property will genuinely be used — and whether you might ever let it
- The purchase price, the deposit available, and where the deposit is coming from
- Your income, and what surplus you'd be comfortable holding after both payments
Advisory promise
When we might tell you to wait
We won't always tell you to buy today.
We may advise waiting where the surcharge Stamp Duty would take the deposit below a better loan-to-value tier, where both payments leave no realistic headroom, or where letting the property is enough of a factor that a holiday-let or buy-to-let structure should be arranged instead.
A second property should add to your life, not consume the margin in it. If the numbers only work in a good year, we'll say so before another footprint goes on your file. We give advice — not just applications.

Common questions about second home mortgages
Our promise
What we'll never do
- Tell you to apply if it won't work
- Send applications everywhere
- Recommend borrowing beyond your budget
- Hide bad news
We don't finance an aspiration. We check that owning two properties works on your numbers before you commit to the second one.
Check what a second home really costs you
Tell us about both properties, how the second will be used and your income — we'll assess what's realistically affordable.
We don't recommend a second-home lender until affordability across both mortgages, the surcharge Stamp Duty and the intended use have all been established.
The deposit is rarely what catches people out. It's the surcharge and the second set of running costs — both knowable before you offer.
