Workflow

How it works

Follow the underwriting path lenders use: input the deal, apply constraints, then read the result.

Step 1

1. Enter market valuation or purchase price

Input RICS Red Book Market Value or contracted commercial purchase price.

UK Commercial LTV Formula

Loan-to-Value (LTV) measures the commercial mortgage facility balance as a proportion of the property's appraised RICS Red Book Market Value.

Read the calculation methodology and limitations.

LTV (%) = (Commercial Facility Balance / Property Market Value) x 100
Borrower Equity = Property Valuation - Facility Balance
Example

A £15,000,000 logistics facility in the Midlands with a £9,000,000 loan facility has an LTV of exactly 60.00%.

Quick facts

  • Post-GFC and under PRA guidance, UK clearing banks generally cap senior CRE facilities between 55% and 65% LTV.
  • LTV is always evaluated alongside debt yield and Interest Cover Ratio (ICR) to ensure cash flow supports the debt service.
