Key Metrics Commercial Lenders Evaluate
Unlike residential consumer mortgages that evaluate personal income multiples, corporate commercial loans are assessed on asset yield, corporate debt capacity, and covenant coverage.
LTVLoan-to-Value Ratio
The percentage of the property’s current open-market valuation that the bank will advance. Standard commercial mortgages typically cap at 70%–75% LTV, while short-term bridging finance caps at 70%–75% gross. Lower LTV tiers (<60%) unlock the most competitive interest margins.
Read Valuations Guide →ICRInterest Cover Ratio

Lenders require rental income to exceed debt payments by 125% for SPV Limited Companies, 130%–135% for mixed-use assets, and 140%–145% for pure commercial units to cushion against voids, repair reserves, and interest rate volatility.
Read Limited Company BTL Guide →LTCLoan-to-Cost (Development)
In ground-up construction and conversion projects, development lenders lend up to 85%–90% of total project costs (land purchase + construction + professional fees + contingency). This minimizes upfront developer equity contribution while construction milestones are funded in staged drawdowns.
