This article explores some buy-to-let financing options for landlords, including first and second charge mortgages, and bridging loans and equity release.
For landlords looking to grow a buy-to-let portfolio, fund refurbishments, or unlock the capital tied up in existing properties, there is a range of buy-to-let financing options available. First charge mortgages, second charge loans, bridging finance, and equity-based products each occupy a different space within the lending landscape, and the right choice depends on what a landlord is trying to achieve, how quickly they need funds, and what their existing mortgage commitments look like. Understanding how these products work and when each is most appropriate is good to understand.
1. First charge mortgages: The foundation of buy-to-let finance
A first charge mortgage is the primary loan secured against a property and the most familiar instrument in a landlord's financial toolkit. When a buy-to-let property is purchased with borrowing, or when a landlord refinances a buy-to-let to release equity or secure a better rate, the lender takes a first legal charge over the property, meaning they are first in line to recover their money in the event of default.
Refinancing on a first charge basis is one of the most widely used strategies for releasing equity. If a property appreciates in value and the gap between its market value and the outstanding mortgage widens, a landlord can potentially remortgage to a higher loan amount against that increased value, drawing out the difference as cash. Landlords released £2.37 billion of equity through buy-to-let remortgaging in 2025, a 60% rise on the prior year.
2. Second charge loans for landlords: Borrowing without disturbing your existing mortgage
A second charge loan sits behind the first charge mortgage in the repayment hierarchy and is secured against the equity remaining in the property after the primary mortgage is accounted for. Its key advantage is that it leaves the existing mortgage entirely undisturbed.
Where a landlord has locked in a competitive fixed rate and would face significant early repayment charges by remortgaging, a second charge loan allows them to access additional funds without triggering those penalties or moving the whole loan balance onto a higher rate overall.
In 2025, the second-charge market reached its highest lending levels since 2008, partly because many landlords found themselves tied to attractive deals which they were reluctant to exit. Second-charge mortgage rates generally fall in the range of 6% to 9% for borrowers with strong credit profiles, reflecting the additional risk the lender carries by sitting in second position. The combined loan-to-value across both charges is a key factor lenders assess, with lower ratios attracting more competitive pricing. The combined interest coverage is another key factor.
3. Bridging loans for buy to let: Speed and short-term flexibility
A bridging loan for buy-to-let is a short-term, interest-only facility designed for situations where speed matters and there is a clear exit strategy. Typical terms run from one to twenty-four months, and most deals in 2026 are being priced between 0.65% and 0.95% per month, depending on loan-to-value and the strength of the exit plan.
Common uses include purchasing at auction, funding refurbishment before refinancing to a longer-term mortgage, acquiring properties that standard lenders will not accept in their current condition, and moving quickly on an opportunity while longer-term arrangements are put in place.
First charge vs second charge bridging
Bridging finance can be arranged as either a first or second charge. A first charge bridging loan is secured against an unencumbered property or one where the bridge replaces the existing mortgage entirely. A second charge bridging loan sits behind an existing mortgage, giving the lender second-priority repayment, which typically commands a higher rate.
Second charge bridging is useful in property development finance scenarios where a landlord needs to fund works on a mortgaged property without remortgaging, preserving an existing deal while releasing capital for the project.
4. Equity-based alternatives: A different kind of property finance
Pauzible offers an equity partnership for buy-to-let landlords in England and Wales. Landlords can release up to £500,000 per property over a chosen term of two, three or five years, paying a modest monthly share of the rent alongside a separate interest cost that can be paid in full monthly or deferred to the end of the loan term.
For the end of the term, the final capital repayment amount is either agreed upfront as a fixed amount or linked to the property's value at that point, provided at least three years of the term have passed. Settling earlier than that means the higher of the property's value then and its value at the outset is used instead, alongside any deferred interest becoming due in full.
With an application-to-funding timeline of three to four weeks and no requirement to disturb an existing mortgage, it is a strong option for landlords who may be equity-rich but cash-constrained. To explore scenarios and how much equity you may be able to release, use our helpful calculator.
Conclusion
Buy-to-let finance options are broad. No single option suits every landlord or situation. The right choice depends on the purpose of the funding, the status of the existing mortgage and the timescale and cost involved. Taking the time to understand each product type and seek specialist advice where needed is the optimal route to a financing decision that works across the life of a portfolio.

FAQs
Q. What is the difference between a first charge and a second charge mortgage?
A. A first charge mortgage is the primary loan secured against a property, giving the lender first priority on repayment if the property is sold or repossessed. A second charge mortgage is an additional loan secured against the same property, sitting behind the first charge mortgage in the repayment queue and carrying a higher interest rate to reflect that risk.
Q. When is a bridging loan for buy to let the right choice?
A. A bridging loan is most appropriate when speed is essential and a clear exit strategy exists, such as purchasing at auction or funding a refurbishment before refinancing. It is usually an expensive short-term financing option and should ideally not be used as a substitute for longer-term finance, if possible.
Q. Can I take out a second charge loan if I am locked into a fixed-rate buy-to-let mortgage?
A. Yes. A second charge loan sits alongside your existing mortgage rather than replacing it. This is a primary reason landlords choose second charge borrowing while holding a competitive deal they do not want to lose.
Q. How much can I borrow on a second charge loan against a buy-to-let property?
A. The amount available depends on the equity remaining after the first charge is accounted for and the combined loan-to-value ratio. Combined LTV for second charge buy-to-let mortgages typically ranges from 60% to 85%, depending on the lender and the borrower's circumstances.
Q. What is the typical term for a bridging loan on a buy-to-let property?
A. Bridging loans generally run from one to twenty-four months, designed to bridge a temporary gap rather than serve as a long-term solution. The exit strategy, whether a sale or remortgage, is central to how lenders assess and price the facility.
Q. How does refinancing a buy-to-let differ from taking out a second charge loan?
A. Refinancing replaces the existing first charge mortgage entirely, which can release equity but may trigger early repayment charges during a fixed-rate period. A second charge loan adds a separate facility without disturbing the first mortgage, making it preferable when the existing rate is worth preserving.
Q. What is equity-based property finance and how does it differ from a loan?
A. Equity-based finance involves sharing a portion of a property's future value in exchange for capital today. Principal repayment is tied to how the property performs over the agreed term.
Q. Are buy-to-let bridging loans regulated by the FCA?
A. Most buy-to-let bridging loans are unregulated, as FCA regulation applies where the borrower or a family member occupies or intends to occupy the property. Landlords using bridging finance for investment properties should seek independent specialist advice before proceeding.
Q. What should I consider before choosing between buy-to-let finance options?
A. The key factors include the purpose of the funding, the size and urgency of the financing required, whether an existing mortgage carries early repayment charges, and the total cost of each option, rather than the headline rate alone.
Q. How does Pauzible's equity product compare to a traditional buy-to-let remortgage?
A. A traditional remortgage replaces the existing loan and releases equity as cash, but resets the mortgage rate and may incur early repayment charges. Pauzible's product leaves any existing mortgage untouched, releasing up to £500,000 per property over a chosen term of two, three, or five years in exchange for a rent share and a separate interest cost, which can be deferred, and with a final repayment due at the end of the term that is either fixed upfront or linked to the property's value.
