Should I set up a revolving credit facility before I need one, or wait until I have a deal?
For active UK buy-to-let (BTL) landlords and property investors, timing is everything. Whether you are bidding at a property auction, upgrading a terrace house to meet modern EPC standards, or covering cash flow during a tenancy void, having immediate access to capital can make or break your investment strategy. When considering a Buy-to-Let Revolving Credit Facility, many landlords face a common dilemma: should you set up the facility proactively before you need it, or wait until you have a specific property deal agreed?
Understanding the mechanics of this specialized property financial product can help you make an informed decision that aligns with your portfolio goals.
What is a Buy-to-Let Revolving Credit Facility?
Not quite what you are looking for? Try these:
To understand the timing of your application, it is important to clarify what this product is. Unlike an unsecured business loan, a business credit card, or generic corporate credit, a Buy-to-Let Revolving Credit Facility is a secured second-charge facility. It is secured against your existing residential buy-to-let property and sits directly behind your current first-charge mortgage.
It functions essentially like a property overdraft. Once your credit limit is approved and legally set up, you can draw down funds, repay them, and draw them down again as often as you like without needing to reapply each time. Crucially, interest is only charged on the money you actually draw down, not on the total limit of the facility.
Option 1: Setting up the facility before you have a deal (The Proactive Approach)
Arranging your facility in advance is often favored by experienced investors who value speed and agility. In a highly competitive property market, being able to move quickly is a distinct advantage.
The advantage of speed
Setting up a second-charge property facility involves legal processes, property valuations, and underwriting. This setup process can take several weeks to finalize. However, once the facility is fully set up, you can typically draw down your funds in as little as 24 to 48 hours. Having this capability in place means you can act almost as a cash buyer when opportunities arise.
Handling property auctions
If you purchase a property at auction, you typically need to pay a 10% deposit on the day and complete the remaining 90% within 28 days. Relying on traditional mortgages or trying to organize new finance from scratch within this short window is highly risky. If you cannot complete on time, you may lose your deposit and face additional charges. Having an active revolving credit facility ready to draw down can comfortably cover these tight auction deadlines.
Managing refurbishments and EPC upgrades
Property refurbishments often present unexpected costs. Similarly, meeting modern Energy Performance Certificate (EPC) requirements can require sudden capital. If you have a revolving credit line ready, you can draw the refurbishment costs instantly to pay contractors, keep the project moving, and avoid costly delays.
Low ongoing costs
Because interest is only charged on the drawn balance, a proactive setup does not mean you will face large ongoing interest bills while the facility sits empty. While there may be initial setup costs, such as valuation and legal fees, the ongoing cost of having the unused facility ready is minimal compared to the cost of losing out on a lucrative deal.

Option 2: Waiting until you have a deal (The Reactive Approach)
Some landlords prefer to wait until they have a specific property under contract before applying for any form of finance. While this approach has some logic, it carries significant risks in the modern property market.
Avoiding speculative fees
The main reason landlords wait is to avoid paying upfront legal and valuation fees for a facility they might not use immediately. If you are unsure whether you will purchase another property in the near future, waiting ensures you only spend money on fees when a transaction is guaranteed.
The danger of transaction delays
The primary downside of waiting is that you cannot access funds instantly. If you find a distressed property deal that requires a fast completion, trying to set up a second-charge facility at that moment may take too long. Sellers who want a fast sale may choose another buyer who already has funds available. If you wait, you may miss out on the best property deals.
How does it compare to bridging finance and remortgaging?
When looking for quick capital, UK landlords generally weigh revolving credit against two traditional alternatives: bridging finance and remortgaging.
Bridging finance
Bridging loans are typically single-use, short-term loans. They can be structured as “closed bridging loans” (where there is a guaranteed exit strategy, such as an active sale contract) or “open bridging loans” (where the exit is planned but not yet finalized). Bridging loans are useful, but they generally roll up interest, meaning you do not make monthly payments, and the total cost can accumulate quickly. If you default on a bridging loan, the implications are severe. Your property may be at risk if repayments are not made. Missing payments can lead to legal action, repossession of the property, increased interest rates, and additional charges.
By contrast, a revolving credit facility allows you to draw and repay multiple times without paying new arrangement fees for every single deal.
Remortgaging
You could remortgage your existing property to release equity. However, remortgaging takes time and can trigger expensive early repayment charges if you are locked into a fixed-rate product. It also forces you to refinance your entire mortgage balance, potentially moving your cheap historical rate to a higher current market rate. A second-charge revolving credit facility avoids this by sitting behind your current mortgage, leaving your cheap first-charge rate completely untouched.
Important risk and compliance considerations
Before proceeding with any secured property finance, you should consider the risks involved. The property (your home or investment property) may be at risk if you do not keep up repayments. It is vital to have a clear exit strategy for any funds you draw down, ensuring you can repay the balance within the agreed terms to avoid default fees or legal action.

Is a BTL revolving credit facility an unsecured loan?
No. A Buy-to-Let revolving credit facility is a secured financial product, registered as a second charge against your residential investment property.
How long does it take to draw money once the facility is active?
Once your revolving credit facility is fully established, you can typically draw down funds into your account within 24 to 48 hours.
Will I pay interest on my credit limit if I do not draw any funds?
No. One of the main benefits of this product is that interest is only calculated on the money you actually draw down, not on the total credit limit.
Can I use this facility to cover tenant void periods?
Yes. Landlords frequently use their credit line to bridge short-term cash flow gaps, such as when a property is empty between tenancies or undergoing repair.
Can I use a revolving credit facility to pay for property auction deposits?
Yes, this is a very common use. Because you can draw funds in 24 to 48 hours, it is ideal for meeting tight 28-day completion deadlines at auctions.
Conclusion: What is the best path for your portfolio?
If you are an active investor who frequently bids at auction, undertakes light refurbs, or manages a growing portfolio, setting up your facility in advance is generally the more practical route. It removes the stress of sourcing finance under tight deadlines and ensures you are ready to move when a bargain appears. If you rarely buy new properties and only need capital for a single, specific project, waiting until the deal is secure might be more suitable for your needs.
