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.

ICRInterest Cover Ratio

The ratio of property rental income to mortgage interest obligations. 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.

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.

Read Development Finance Guide →

GDVGross Development Value

The projected aggregate open-market value of the completed development scheme. Lenders maintain an overarching borrowing cap of 65%–70% of GDV to ensure that project sales comfortably redeem the principal debt, accrued interest, and arrangement fees upon project completion.
