Enter a few details below to get an estimate of your borrowing potential.

Whether you’re investing in your first commercial property, expanding your portfolio, or refinancing an existing loan, our commercial mortgage calculator helps you estimate how much you can borrow based on the income from the property.

How much you could comfortably borrow?

Our Commercial Mortgage Calculator provides a quick, high-level estimate of how much you could borrow for a commercial investment property. However, it’s important to note that the actual borrowing amount can vary significantly depending on several factors:

  • Lender Criteria: Each lender has its own approach to assessing affordability and risk.
  • Property Type: Mixed-use properties, specialized units, or multi-tenanted properties may influence the amount you can borrow.
  • Covenant Strength: The financial stability of tenants and lease agreements play a significant role in determining borrowing capacity.
  • Product Type: The terms of the mortgage, such as fixed or variable rates and loan term length, also affect calculations.

Frequently Asked Questions

What Factors Affect How Much I Can Borrow for a Commercial Mortgage?

Several factors influence your borrowing capacity, including the property type, rental income, loan-to-value ratio, lender-specific criteria, and the strength of the tenant covenant. Each lender evaluates these factors differently, making it essential to understand their specific requirements.

How Do Lenders Assess Interest Rates for Commercial Mortgage Affordability?

Lenders typically account for two key aspects when assessing affordability:

  1. Coverage for Rental Voids: Lenders often require the rental income to cover mortgage payments by 125% to 145% to account for potential void periods or unexpected expenses. This ensures that the property remains financially viable even during periods of reduced income.

  2. Interest Rate Volatility: To mitigate the risk of interest rate fluctuations, lenders apply different stress tests depending on the product type. For five-year fixed-rate mortgages, they often stress test at the actual pay rate, providing greater certainty. However, for two- or three-year fixed, variable, or tracker mortgages, which don’t offer long-term rate stability, lenders typically add an additional 1–2% on top of the product rate to ensure repayments remain affordable under changing market conditions.

 

Can I Use the Commercial Mortgage Calculator for Mixed-Use Properties?

Yes, the calculator can provide an estimate for mixed-use properties, such as those with commercial units on the ground floor and residential spaces above. However, the actual amount will depend on the proportion of commercial versus residential use and how lenders assess the property.

How Do Tenant Covenant Strength and Lease Agreements Impact Borrowing Capacity?

The financial stability of tenants (covenant strength) and the length of lease agreements are crucial factors in determining how much you can borrow. Properties with long-term leases and reliable tenants are seen as lower risk, offering predictable rental income, which may allow for higher borrowing limits or better terms. On the other hand, shorter leases or tenants with weaker financial profiles could lead to stricter lending criteria or reduced borrowing capacity.

How Can I Get a More Accurate Borrowing Estimate?
