Commercial investment mortgages

A commercial investment mortgage finances property let to business tenants. The rent is expected to service the loan, so lenders study the lease and the tenant as closely as the building. A modern lease to an established tenant tells a very different story from a short lease, an imminent break or an empty unit.

Lease and covenant

Covenant strength describes how reliable the tenant is likely to be at paying rent. Lenders may review tenant accounts, credit information and payment history. They also read the lease: the unexpired term, break options, rent review provisions, repairing obligations and any rights the tenant has to renew.

Multi-let properties spread risk across several tenants, but each lease adds legal work and potential gaps.

Vacancy and income gaps

Empty space brings no rent and can bring business rates, insurance and security costs. Lenders will consider how likely the space is to let and on what terms. A part-vacant building may be financeable, but the lender will usually look harder at your wider finances and the local letting market.

Condition and obsolescence

Ageing buildings may need investment to remain lettable, and energy performance requirements for let commercial property may affect future letting. Valuers consider whether the building is likely to stay attractive to occupiers. Ask for survey information before you commit.

Your role as investor

Even where rent covers the loan, lenders may assess your experience, other borrowing and personal resources. Purchase structure, whether personal, company or partnership, affects tax and lender options.

Hypothetical example, not a real client: an investor considers a small parade of shops with a mix of tenants and one empty unit. A lender might discount the vacant unit and focus on the remaining leases, their lengths and break dates.

Rent review, lease end and renewal rights

The rent a tenant pays today is not necessarily the rent you will receive in future. Rent reviews may move it up or, depending on the drafting, keep it flat. When a lease ends, the tenant may have a statutory right to renew in England and Wales unless the lease was contracted out of that protection, which affects both your control and the security of income.

Lenders and valuers read these clauses because they shape future income. Ask your solicitor to summarise the key dates and rights for each lease before you approach lenders, so you can explain the income profile clearly rather than letting the valuer discover it.

Rent arrears and service charges

Arrears tell a lender a lot about a tenant. A record of late or partial payment may lead a lender to discount that income or ask for more of your own resources. Service charges and insurance rent recovered from tenants also matter: if you cannot recover them, those costs reduce the net income available for the loan.

If you are buying, ask the seller for a rent ledger and service charge accounts as part of due diligence. Unexpected arrears discovered late can derail an offer.

Managing the property after completion

Lenders often include obligations in the loan terms: keeping the property insured and in repair, seeking consent before granting or changing leases, and supplying updated rent information. Breaching these can matter even if payments are up to date. Read the covenants in your offer and build a simple routine to meet them, or appoint a managing agent who understands them.

Your property may be repossessed if you do not keep up repayments on a loan secured on it. Sorbus Finance is a broker, not a lender. Finance is subject to lender criteria, status, valuation and affordability. We work with a panel of lenders, not the whole market, and do not promise a rate, fee level or outcome.

Before you apply

Preparation checklist

  • Obtain copies of every lease, licence and side letter.
  • Prepare a tenancy schedule with rents, dates, breaks and arrears.
  • Check whether any part is residential or occupied by you or family.
  • Review energy performance and condition before offering.
  • Budget for voids, repairs not recoverable from tenants and management costs.
  • Agree ownership structure with your accountant.
Questions

Common questions

What does tenant covenant mean?

It describes how financially reliable the tenant is likely to be in paying rent and meeting lease obligations.

Can I finance a property with a vacant unit?

Sometimes. Lenders usually discount empty space and look more closely at your other resources and the letting prospects.

Does a break clause matter?

Yes. A tenant who can leave early creates income uncertainty, which lenders factor in.

Is a lease to my own company an investment?

Lenders may treat it differently from an arm's length lease and still assess your trading business. Discuss the structure openly.

Can I buy in a limited company?

Many lenders consider company borrowers, usually with director guarantees. Tax treatment differs, so speak to your accountant.

Is the rent guaranteed to cover payments?

No. Tenants can fail or leave, and rates can change. Plan for income interruptions.
