Can I get a commercial mortgage to purchase office premises?

Yes. Commercial mortgages are available for office premises — either owner-occupied (for a business to trade from) or as an investment (to let to office tenants). The assessment approach differs between the two.

What deposit is needed for an office commercial mortgage?

Deposits for office commercial mortgages typically range from 25% to 40% of the purchase price or valuation. The exact requirement depends on the office type, location, occupancy and the borrower's financial profile.

Are professional practice offices eligible for owner-occupied commercial mortgages?

Yes. Law firms, accountancy practices, dental and medical practices and other professional businesses can access owner-occupied commercial mortgages to purchase the premises from which they operate. These are assessed on the practice's trading performance and ability to service the debt.

How are vacant or partly let office buildings assessed?

Partially let or fully vacant office buildings present additional complexity for lenders, as there is no current rental income to support the assessment. Lenders may require larger deposits, apply stricter criteria or require evidence of potential lettability before proceeding.

Are serviced offices eligible for commercial mortgage finance?

Serviced office buildings can attract commercial mortgage finance, though the assessment is more complex than for a standard let office. Short-term licence arrangements rather than formal leases, and the operational nature of the business, mean that specialist lender consideration may be required.

Office Commercial Mortgage Finance

Commercial mortgages for office premises can be arranged on both owner-occupied and investment bases, covering a wide range of office types — from professional practice premises and single-tenanted office buildings to multi-let office investments and serviced office centres.

Owner-Occupied Office Mortgages

Professional firms, businesses and practices purchasing the office premises from which they operate are assessed on the financial performance of the business. Lenders review business accounts, profitability and the ability of the business to service the mortgage from its operating income.

Solicitors, accountants, architects, engineers, dental and medical practices and other professional firms commonly use owner-occupied commercial mortgages to secure their business premises. This can provide long-term security of tenure and asset-building benefits compared to renting.

Office Investment Mortgages

Investors purchasing office buildings to let to business tenants are assessed on the rental income, tenant quality (covenant strength), lease terms and occupancy of the building. Multi-tenanted buildings with a diversified income stream are often viewed more favourably than single-let offices where all rental income depends on one tenant.

Serviced Office Buildings

Serviced office centres — where desk space or offices are let on short-term licences rather than formal leases — present a different profile from a traditional office investment. The underlying property may have strong occupancy, but the absence of formal long leases and the operational nature of the business model means specialist lender assessment is typically required. Some lenders will consider well-established serviced office operations with strong occupancy records.

What Lenders Consider for Office Mortgages

✓ Owner-occupied: business accounts, profitability and trading history
✓ Investment: rental income, tenant covenant and lease terms
✓ Office location, specification and marketability
