Can I use a revolving credit facility like a property overdraft?

Can I use a revolving credit facility like a property overdraft?

For UK buy-to-let landlords and property investors, managing cash flow is a constant challenge. When a new investment opportunity arises, waiting months for a traditional mortgage to clear can mean missing out on a lucrative deal. If you are looking for a flexible way to fund your next project, you may have asked: can I use a revolving credit facility like a property overdraft?

The short answer is yes. A buy-to-let revolving credit facility functions in much the same way as a property overdraft, offering you a pool of pre-approved capital that you can access whenever you need it. However, it is essential to understand how this product works, how it differs from traditional borrowing, and the risks involved before you apply.

What is a Buy-to-Let Revolving Credit Facility?

A buy-to-let revolving credit facility is a specialised financial product designed specifically for UK landlords. It is vital to note that this is a secured facility. Unlike a personal credit card or an unsecured business loan, this facility is secured as a second charge against an existing residential buy-to-let property. This means it sits directly behind your existing first-charge mortgage.

Because the facility is secured against the equity in your property, it is not an unsecured product. This security typically allows lenders to offer higher credit limits and more competitive interest rates than you could obtain through unsecured business revolving credit lines. Promise Money is an FCA-authorised broker (Ref: 681423) — not a lender — that can help you compare these products to find a suitable solution for your portfolio. You can learn more about how this works on the promisemoney.co.uk/landlord-revolving-credit-100 hub page.

How the Property Overdraft Concept Works

Using a secured revolving credit facility is highly straightforward and operates just like a traditional bank overdraft, but on a much larger scale. Here is how the process typically works for property investors:

  • Apply Once: You arrange the facility based on the available equity in your buy-to-let property.
  • Draw Down Speed: Once the facility is fully arranged, funds can typically be drawn in 24 to 48 hours.
  • Pay Only for What You Use: Interest is only charged on drawn amounts, not on the full facility limit. If your limit is £100,000 but you only draw £20,000, you only pay interest on the £20,000.
  • Repay and Reuse: As you repay the balance, your available credit limit restores. You can draw down those funds again for your next project without having to submit a new application.

Real-Life Landlord Scenarios

How do property investors use this property overdraft facility in the real world? Here are a few common scenarios where revolving credit proves highly useful:

  • Auction Deposits: Purchasing a property at auction requires speed. You must typically pay a 10% deposit on the day of the auction, with the remaining balance due within 28 days. A revolving credit facility allows you to draw down the deposit immediately, giving you time to arrange long-term financing.
  • Refurbishments and EPC Upgrades: Making a property ready for tenants or upgrading insulation to meet modern energy standards can be expensive. You can use your facility to pay contractors and purchase materials, then repay the balance once the property is let or remortgaged.
  • Covering Void Periods: If a tenant leaves unexpectedly, your first-charge mortgage payments do not stop. You can draw from your property overdraft to cover the mortgage and maintenance costs, then repay it when a new tenant moves in.
  • Bridging Remortgage Gaps: If you are waiting for a slow remortgage to complete but need deposit funds immediately to secure another property, the revolving facility can temporarily bridge that gap.

Revolving Credit vs. Bridging Finance and Remortgaging

When landlords need to raise capital, they traditionally look at remortgaging or bridging finance. It is helpful to compare these alternatives to see why a revolving credit facility may be a highly flexible choice.

Remortgaging

Remortgaging involves refinancing your existing first-charge mortgage to release equity. While this can provide a lump sum of cash, it is often a slow, rigid process. Additionally, if you currently benefit from a low historical interest rate on your primary mortgage, remortgaging the entire balance could force you onto a much higher rate. A secured revolving credit facility sits as a second charge, meaning your attractive first-charge mortgage remains completely untouched.

Bridging Finance

Bridging loans are short-term loans designed to transition a buyer from one transaction to another. They generally fall into two categories: open bridging loans and closed bridging loans.

A closed bridging loan has a firm, realistic exit plan, such as an agreed sale contract on another property. An open bridging loan is used when the exit date is less certain, though it typically must still be repaid within a set timeframe, usually 12 months. Crucially, most bridging loans roll up interest, meaning monthly payments are not typical, and the entire balance is repaid at the end. While useful, bridging loans are single-use products. Once you repay them, the facility is closed. A revolving credit facility provides a permanent, reusable safety net without the need to pay arrangement fees for every single project.

Understanding the Risks

While a property overdraft offers excellent flexibility, it is a serious financial commitment. Your property may be at risk if repayments are not made. Because this facility is secured as a second charge against your residential buy-to-let property, failing to meet your financial obligations can have severe consequences.

If you do not keep up with your repayments, the lender may take legal action. This can result in the repossession of your investment property. Furthermore, defaulting on your payments could lead to increased interest rates, additional administrative charges, and negative marks on your credit profile, making it harder to secure funding in the future.

Before applying for any secured facility, it is highly recommended to check your current credit status. Lenders will perform comprehensive credit assessments during the application process.

Conclusion

A buy-to-let revolving credit facility offers UK property investors a highly flexible way to manage cash flow, acting just like a property overdraft. It allows you to draw down funds quickly, pay interest only on what you use, and reuse the facility as your portfolio grows. However, because it is secured as a second charge against your property, you must ensure you can comfortably meet the repayments to avoid the risk of repossession.
