Commercial Bridging Finance: Funding a Property Before the Rent Roll Exists

You have found the asset. The location is right, the price is achievable, and you have a plan to let it. The problem is that a bank won't lend against it until there are tenants in place, and there are no tenants in place yet.

This is the stabilisation gap. Commercial mortgage lenders underwrite against Net Operating Income: if there is no income, the coverage calculation returns zero and the loan fails before the credit committee sees it. It doesn't matter how strong the location or how clear the letting prospects are. Contracted income is required before a conventional lender will commit.

Commercial bridging finance is built for this precise situation. The lender values the asset as it stands, funds the acquisition or refinance on that current value, and gives the borrower time to create the rent roll that supports the exit. Understanding the loan structure and LTV methodology in advance is what determines whether a bridge solves the problem or merely defers it.

Why Commercial Lenders Need a Rent Roll First

A commercial mortgage is sized against the property's Net Operating Income. The lender divides that income by the annual debt service to produce a Debt Service Coverage Ratio; most commercial lenders require 1.25x to 1.5x coverage before the loan passes credit. A vacant building has no income, so coverage is zero and the loan fails at the first screen.

This logic holds whether the property is an office in the City of London, a shophouse on Club Street in Singapore, or a retail parade anywhere in between. The lender needs contracted income, not projected income. Heads of Terms with a prospective tenant, comparable rents on neighbouring units, and a credible track record from the borrower are useful context, but none of them replaces a signed lease.

In the UK, the Bank of England's base rate feeds directly into the hurdle rates commercial mortgage lenders set for coverage and pricing, making the income-first test more rigorous when borrowing costs are elevated. In Singapore, banks apply their own commercial loan credit policies that similarly anchor to demonstrable rent before committing to a facility.

How a Bridge Buys the Stabilisation Window

A commercial bridging loan operates on different underwriting logic. The lender values the asset as it stands today, vacant, part-let, or mid-refurbishment, and lends against that current value rather than projected income. The borrower gets a short-term facility, typically 3 to 24 months, to complete the stabilisation work: secure a tenant, execute a lease, carry out refurbishment if needed, or resolve a planning condition.

Rolled-up interest, where interest builds into the loan balance rather than being paid monthly, preserves working capital during a period when the property is generating no income. This is a material point for borrowers managing fit-out costs or leasing incentives at the same time. The lender holds a first charge over the asset throughout.

Speed is a practical advantage. A term sheet typically arrives within 24 hours of a complete enquiry; drawdown typically completes in two to three weeks, with urgent situations often resolving in under seven days. That timeline can meet auction deadlines, vendor completion dates, or refinance pressures that a commercial mortgage application cannot.

LTV Methodology on a Vacant Commercial Asset

The LTV is calculated against the current 'as is' value, not against what the property will be worth once let. A building with a projected fully-let value of £5M may carry an 'as vacant' valuation of £3.5M; a 70% LTV on that lower figure produces a £2.45M loan. The difference between those two numbers is the equity buffer the lender needs to absorb bridge costs and still refinance cleanly at term.

This conservatism is deliberate. If the stabilisation plan fails and the exit doesn't materialise, the lender's security is the asset as it stands today, not a projected value that depends on events that haven't happened yet. Lending against the higher figure would leave the lender exposed on any enforcement scenario.

In Singapore, indicative LTVs on commercial assets including shophouse bridging loans and office bridging loans run up to 70%. For UK commercial bridging loans, the ceiling typically reaches 75%. Both figures are subject to valuation, due diligence, and the specific asset's risk profile: location, tenure, covenant of any existing tenants, and the visibility of the exit all affect the actual number.

What the Exit Must Look Like Before the Bridge Is Drawn

A bridge is a short-term instrument with a hard stop. The exit is not deferred to the end of the term: a lender models it from the moment you submit an enquiry, because a bridge that doesn't produce a viable refinance position at term is a loss for everyone involved.

A credible exit for a commercial bridging loan requires three things. An executed lease, or near-exchange Heads of Terms, with a tenant of reasonable covenant. Projected income that supports the debt service of the refinancing commercial mortgage, meaning the Net Operating Income once tenanted will cover the new lender's DSCR requirement. And a timeline that fits inside the bridge term with enough margin for slippage.

What doesn't constitute a credible exit: letting income projected at above-market rents, a timeline with no buffer for a delayed signing, or a refinancing quantum that assumes a fully-let value the lease hasn't yet created. A private lender assesses this before issuing terms. For a worked example of how exit structure shapes deal underwriting on a large commercial asset, see our £18.8M facility against a West London hotel.

When commercial bridging finance is not the right tool. If the stabilisation cost outweighs the margin between current value and exit value, the arithmetic doesn't work. If letting prospects are speculative rather than backed by active leasing evidence, the exit is not credible. And if the LTV required against current value exceeds what the lender can offer, a bridge won't cover the full funding gap. The honest test: does the stabilised value support a refinance that repays the bridge, covers accrued rolled-up interest, and leaves the borrower solvent? If not, a bridge defers the problem rather than solving it.
