Remortgaging a second home is something we get asked about all the time at Heron Financial.

This guide walks through what’s possible, what lenders look at, what changes depending on how the property is used, when to start the process, and where the most common pitfalls are.
Can I remortgage my second home?
Yes — remortgaging a second home is definitely something that can be done. It’s viable, but it’s very situation-based, depending on the use of the property and your financial circumstances. The starting point is an assessment to understand the needs and requirements, but in general, it can be done.
Does it matter if it’s a holiday home or a buy-to-let?
Yes, the use of the property is quite important.
If it’s any sort of investment property, a holiday let or a buy-to-let, the assessment is going to be heavily dependent on the rental income the property is receiving. If it’s a second home for personal use, a holiday home, or a property where a dependent relative lives, then it’s more based on your personal income and outgoings — less about any rent, and more about your overall financial circumstances.
That can also change the loan-to-value caps — how much mortgage you can raise up to. As a rough standard, if it’s an investment, you’ll typically be looking at around 75–80%. If it’s more of a second home where family members live or it’s a weekend place, you could potentially go higher — around 85–90%, depending on the lender. So it does come down to the use of the property and what we’re using to assess.
Is the process different from remortgaging your main home?
A remortgage in itself is a fairly standard process across the board in terms of how it’s assessed, looking at lender options based on the situation, the property’s current use, financial circumstances, and so on. That doesn’t change too much.
The main difference, as above, is whether the property is an investment, a holiday let or a second home will affect which lenders are available to you.
Why do people remortgage a second home?
There are a few common reasons.
A lot of the time it’s about pulling out equity. If it’s an investment property and you’re looking to buy a new investment, you can release equity from this one to allow that to happen. You can also pull equity from a second home to bring down the mortgage on your main residence and offset things — using the second home as a vehicle to take money out, reduce payments on your main property, knowing that if you’ve got a tenant in there, the rental income can help cover those mortgage payments.
It could also simply be that you’ve already got a mortgage on it, the deal is coming to an end, and it naturally needs reviewing to avoid moving on to a higher rate once that deal does end.

Could it just be about getting a better rate?
Yes, that’s definitely something that can be looked at, depending on circumstances.
It could be that your deal is ending and a new rate could improve things at renewal. It could be that you’re on quite a high rate, and even before your deal ends we can look at remortgaging onto something cheaper in the market.
What we have to take into account is any fees you’d incur if you leave your current deal early. So on a cost-assessment basis, we work out: if you leave early and pay an early repayment charge, does the new rate still leave you with an overall saving? That’s the key question.
What happens when a fixed rate is ending on a second home mortgage?
Very similar to a main residence — when the rate naturally comes to an end, you’d usually start reviewing the mortgage options within the last six months of that deal ending. The simple reason for the six-month window is that mortgage offers usually last around six months, so it ensures we’ve got an offer in place that runs through to the day your current deal ends.
If you decide to do nothing once that rate ends, you’ll move on to your lender’s standard variable rate, or SVR. That’s a higher rate the lender sets, often loosely linked to the Bank of England base rate, with a margin above it. It’s almost always higher than the rate you’ve moved off, so we usually want to avoid that. The only real exception is if you’re selling the property and the sale is going to complete very soon after your deal ends, in which case it may not be worth committing to a new deal.
The vast majority of the time, we want to make sure that when the deal ends, something better is ready to replace it.
How do lenders decide if you can afford to remortgage a second home?
Lenders can be stricter on a second home, and again it comes back to the use of the property.
If it’s a second home for your personal use or for a dependent relative, lenders are stricter, because they’ll take into account the running costs and mortgage for that property as well as for your main residence — to make sure that, based on your personal earned income, it’s all genuinely achievable and affordable.
If the property is an investment property or holiday let, it’s more based on the rental income, so it’s not as strict on your personal affordability. Either way, there are different ways lenders approach it.
Can I release equity from my second home?
Yes, you can. But it’s very situation-dependent and very LTV-dependent, because the LTV caps can be stricter depending on the use of the property.
What we find a lot of the time is that people use released equity for debt consolidation. That covers unsecured debts; credit cards, personal loans, overdrafts, hire purchase or PCP. Anything that isn’t already secured against a property is unsecured, and that can be incorporated into the mortgage.
The benefit is that it can reduce the overall payment. You’ve got everything in one place, it becomes secured, and you’re often paying a lower interest rate than you would on those unsecured products — especially on credit cards, where rates can be very high.
The other common use is gifting equity to children. Some people have younger children looking to buy and take money out to give them as a deposit for a purchase. There are ways this can be done as a gift or as a loan. If it’s structured as a loan, the parent can effectively have a charge on the child’s property, so when that property is sold in the future, they receive a share of the equity back.
Does the purpose of the property change the remortgaging options?
Yes. The purpose of the property has a real impact.
On the investment side, holiday let or standard buy-to-let, you’ll typically be looking at the lower LTV caps of around 75–80%. So if your mortgage is already at 70%, that limits how much you can take out.
Lender options also change even on a like-for-like remortgage where you’re not raising additional borrowing — the panel of lenders available is different for an investment property compared to one held in your personal name. The main thing is the use of the property and the impact that has on LTV and lender options.
The biggest mistakes people make when remortgaging a second home
The biggest one is probably the assessment of what people believe their property is worth. That can often be quite skewed, and what we find is that when the valuation is done and the figure doesn’t agree with the homeowner’s expectation, it can affect the application and the rate we’ve applied for.
Especially in a more difficult market where rates have been moving, what can happen is: we submit the application, the valuation comes back a week later lower than expected, and by that point the rate we’d applied for might no longer be available — because the lender hasn’t agreed the value, and rates may have moved in the meantime. So we always want to use as realistic a property value as possible going in.
The other one is taking on a lot of debt just before a mortgage application. Lenders will assess that. And even if it’s an investment property, where lenders typically don’t dig as much into your personal outgoings, that doesn’t mean they won’t — because they can. If a lender feels you’re “over-indebted” — meaning your debt-to-income ratio is too high — they may not want to take on the risk regardless of the situation.

Your home may be repossessed if you do not keep up repayments on your mortgage.
FAQs
Will I need a solicitor to remortgage?
Yes. Whenever you change lender, a solicitor is needed to transfer the charge over the property. The lender will usually offer either a free legal service or a cash-back contribution that lets you instruct your own solicitor.
How do lenders work out what my second home is worth?
The lender instructs an independent RICS-certified valuer, who uses local comparables — typically around three similar properties sold in the last six months or so within roughly half a mile to a mile — to arrive at a value.
What happens if I do nothing when my second home mortgage deal ends?
Your lender will move you on to its standard variable rate (SVR), which is almost always higher than the deal you came off. In most cases, it’s worth arranging a new deal in advance to avoid that.
