Loan to value (LTV) is the ratio of a loan to the value of the property used as security. In commercial property finance, LTV is the primary lever controlling how much a lender will advance — and its interplay with property type, use, and income determines the terms available to a borrower.

How LTV Is Calculated

LTV = (Loan amount ÷ Property value) × 100

A £750,000 loan secured on a property valued at £1,000,000 = 75% LTV.

The property value used in the calculation is typically the lender’s own valuation — obtained from a RICS-qualified surveyor — not the purchase price or the borrower’s estimate. Where the purchase price and valuation differ, lenders generally use the lower of the two (or the lender’s own assessment). [VERIFY current practice across commercial mortgage and bridging markets]

Commercial LTV vs Residential LTV

Residential mortgages regularly operate at 75–95% LTV. Commercial property lending is structurally more conservative:

  • Commercial mortgages: typically 65–75% LTV for standard properties [VERIFY current market norms]
  • Bridging loans on commercial property: typically 65–75% LTV [VERIFY]
  • Development finance: usually expressed as Loan to Cost (LTC) or as a percentage of Gross Development Value (GDV), not simple LTV

The lower LTV limits reflect commercial property’s characteristics: lower liquidity, wider value volatility, vacancy risk, and the complexity of enforcing security on occupied commercial premises.

How Property Type Affects LTV

Not all commercial property attracts the same maximum LTV. Lenders adjust limits based on the perceived liquidity and stability of the underlying asset:

Higher LTV typically available:
– Standard high street retail in established locations
– Office buildings in major cities
– Industrial and warehouse units

Lower LTV typically available:
– Specialist commercial property (hotels, petrol stations, pubs, care homes)
– Mixed-use properties with unusual configurations
– Properties with vacant possession risk or single-tenant dependency
– Distressed or non-income-generating commercial property

[VERIFY current lender positions — LTV limits for specialist assets vary materially between lenders]

LTV and Loan Pricing

LTV is a core pricing variable. Lenders charge more — higher margins above the base rate — for higher LTV lending because their exposure relative to security is greater. A loan at 70% LTV will typically be priced better than the same loan at 60% LTV from the same lender, because the lender’s downside protection is lower at the higher ratio.

For commercial borrowers, reducing LTV (through a larger deposit or additional security) is one of the most direct ways to improve loan terms.

LTV for Bridging on Commercial Property

Commercial bridging loans use the same LTV mechanics but typically have stricter limits and more variable pricing. The short-term nature of bridging (typically 3–18 months) does not reduce the LTV ceiling — lenders apply the same or more conservative LTV limits than for commercial mortgages, because the exit strategy (sale or refinance) is less certain at the point of origination.

Second charge bridging — where the loan sits behind an existing first charge — typically faces lower effective LTV limits because the first charge must be taken into account. Combined LTV (including the existing charge) is what lenders assess. [VERIFY]

LTV and Valuation Risk

In commercial property, the valuation itself carries more uncertainty than in residential markets. Two RICS valuers assessing the same commercial property may reach materially different figures. Lenders are aware of this and may apply a more conservative view than the stated valuation in their credit decision.

For borrowers, this means the headline “65% LTV product” may in practice deliver a lower advance than expected if the lender applies a conservative internal valuation. [EDITORIAL JUDGEMENT]

Key Terms

  • Open market value (OMV): what the property would sell for on the open market — the standard basis for commercial valuations
  • 90-day forced sale value: what the property would realise if sold within 90 days — used by some lenders for maximum exposure calculations; typically 10–20% below OMV
  • Reinstatement value: insurance rebuild cost — not used for LTV calculations
