Commercial Buy-to-Let Mortgages Finance
Commercial buy-to-let mortgages provide long-term funding for investors purchasing or refinancing income-producing property. Loan terms are typically based on rental income coverage, lease structure and loan-to-value, rather than personal income alone.
At Christie Finance, we arrange commercial buy-to-let finance across a wide panel of lenders, including banks, challenger lenders and specialist funders, ensuring the most suitable structure for each asset and portfolio.
Key Factors to Consider
When you’re thinking about taking out a buy to let mortgage, there are various things that both you and a potential lender will need to consider:
- Tenant status: Has the tenant expressed a desire to vacate in the next 12 months?
- Documentation: Do you have the relevant certificates to ensure the property is let lawfully?
- Professional costs: Have you considered costs such as lender’s solicitor costs and valuation fees?
- Taxes: You may be required to pay capital gains tax, income tax, and land transaction tax.
- Insurance: Buildings insurance and landlord insurance are essential for rental properties.

Commercial Buy-to-Let vs Other Property Finance
Commercial buy-to-let is designed for long-term investment in income-producing property and is repaid over years, with lending decisions based on rental yield and asset value.
A commercial mortgage is typically used where the borrower occupies the property as part of their business, rather than letting it to tenants.

Commercial Buy-to-Let FAQs
What types of property qualify for commercial buy-to-let?
Commercial buy-to-let typically covers mixed-use, semi-commercial property, MUFBs and other income-producing assets that fall outside standard residential lending.
Can commercial buy-to-let be arranged through an SPV or limited company?
Yes. Many commercial buy-to-let mortgages are arranged through SPVs or trading companies, with lending assessed on the property and rental income rather than personal earnings.
How is affordability assessed for commercial buy-to-let?
Affordability is usually based on rental income coverage, lease terms and tenant quality, rather than personal salary. Loan-to-value and asset type also play a key role.
Can I use commercial buy-to-let after refurbishment or conversion?
Yes, once work is complete and income is stabilised. In some cases, Development Finance or Bridging Finance is used initially before refinancing onto a commercial buy-to-let mortgage.
Is commercial buy-to-let suitable for portfolio investors?
Commercial buy-to-let is commonly used for portfolio acquisitions and refinances, particularly where assets are held in limited company structures.
