People sometimes ask whether they should use bridging finance or a commercial mortgage as if the two were alternatives. Occasionally they are. More often, they do different jobs, and the real question is which job you need doing right now.
This guide compares the two side by side and explains how they frequently work together on the same property.
The short version
A commercial mortgage is long-term finance for property that is ready to be occupied or let. It is assessed on the income the property or business generates and is repaid over years.
Bridging finance is short-term finance used to cover a gap: to complete quickly, to fund works, or to hold a property until it can be sold or refinanced. It is assessed mainly on the security and the exit, and is repaid within months.
Comparing the two
Purpose
A mortgage is for holding property. Bridging is for getting from one position to another: from auction to ownership, from unlettable to let, from no planning to planning, from purchase to sale.
Speed
Bridging is generally quicker to arrange. Lenders are set up to move fast, and the assessment focuses on fewer things. A commercial mortgage involves a fuller review of the business or tenants, a valuation and more extensive legal work, and typically takes longer. Exact timescales depend on the lender and the deal in both cases.
Cost
Bridging is usually more expensive. Interest is quoted monthly, fees are often higher, and the total cost over even a short term can be significant. A commercial mortgage is priced for the long term and is generally cheaper on a like-for-like basis. This is why bridging is used for a purpose, not as a default.
Term
Bridging terms are usually measured in months. Commercial mortgage terms are measured in years.
How lenders assess them
For a mortgage, lenders want to see that the income (trading profits or rent) comfortably covers the repayments. For bridging, lenders focus on the value of the security and whether the exit is realistic. This means bridging can sometimes be arranged for a property or borrower a term lender would not consider, at least not yet.
Interest payments
Mortgage interest is paid monthly. Bridging interest can be serviced monthly, retained from the loan at the outset, or rolled up and paid at the exit, depending on the lender.
When bridging tends to be the right tool
- You need to complete within a timeframe a mortgage cannot meet, such as an auction deadline.
- The property is not yet in a condition a term lender will accept, for example vacant, in poor repair or mid-refurbishment.
- You are buying a site or building before planning is granted.
- You are waiting for the sale of another asset to complete.
- You have a clear, realistic exit within months.
When a commercial mortgage tends to be the right tool
- The property is ready to occupy or already let.
- The business or rental income supports the repayments.
- You intend to hold the property for years rather than months.
- There is no time pressure that a mortgage timescale cannot accommodate.
- You want the lowest cost over the long term.
How they often work together
In many commercial deals, bridging and a mortgage are two stages of the same plan:
- A business buys a tired industrial unit at auction using bridging finance.
- It refurbishes the unit over several months.
- Once the works are complete and the business has moved in, it refinances onto a commercial mortgage, which repays the bridge.
Here the bridge makes the purchase possible and the mortgage makes it sustainable. The key is that the mortgage, which is the exit, is realistic before the bridge is taken. A specialist will usually want to think about both stages at the same time.
Questions to ask yourself
- Is the property ready for a term lender now? If yes, a mortgage is probably the direct route.
- Is there a hard deadline? If so, can a mortgage realistically meet it?
- If I bridge, how exactly will I repay it, and by when?
- What is the total cost of the bridge over the term I actually need, including fees?
- What happens if the exit is delayed?
Where FundingFrame fits
FundingFrame does not advise on which route to take. Our checker asks about the property, the amount, the timescale, the condition of the property and, for short-term finance, the exit, and structures your answers into a Deal Snapshot. Where appropriate, we introduce it to a specialist commercial finance broker who can discuss whether bridging, a mortgage, or both in sequence makes sense for your deal.
Key points
- A commercial mortgage is long-term finance for property that is ready to occupy or let.
- Bridging is short-term finance to cover a gap and is repaid within months.
- Bridging is faster and more flexible but generally more expensive.
- Mortgages are assessed on income; bridging on security and exit.
- The two frequently work together: bridge to buy and improve, mortgage to hold.
- Always know the exit, the total cost and what happens if the plan slips before taking a bridge.
