Commercial Mortgages
in Boston

Securing a commercial mortgage for your Boston property requires matching the asset with a lender whose criteria align with your property type, tenant profile, and investment strategy. The commercial lending market includes high-street banks, building societies, specialist commercial lenders, insurance company lending arms, and debt funds, each with different appetite, pricing, and underwriting approaches. The residential market fundamentals in Boston, with a median price of £190,000, support commercial property values and rental demand in the area.

Unlike residential mortgages, commercial lending is an individually underwritten product where the property's income characteristics drive the terms. Rental coverage ratios, tenant covenant strength, lease length, and the weighted average unexpired lease term (WAULT) all influence the rate and leverage available to you. A commercial mortgage broker who understands the Lincolnshire investment market can position your application to highlight the property's strengths and address potential concerns.

We arrange commercial mortgages from our panel of 100+ lenders for offices, retail units, industrial premises, warehouses, mixed-use buildings, and specialist commercial property across Boston and the wider Lincolnshire area. Submit your property details for indicative terms.

The live Boston planning register currently shows 32 residential applications awaiting decision in Boston, together proposing 238 units. The largest — at Near PE20 1AS — proposes 66 units. That pipeline is a useful gauge of both local competition and lender familiarity with Boston schemes.

Against Boston's £190,000 residential median, commercial and semi-commercial lot sizes in the town remain accessible: a 70% LTV commercial mortgage on a £380,000 mixed-use asset means a facility around £266,000, assessed principally on rental cover.

Our commercial mortgage service covers acquisition finance for purchasing income-producing commercial property, refinancing existing commercial debt onto better terms, equity release from owned commercial assets, and portfolio finance for investors with multiple commercial properties. We also arrange development exit finance for developers transitioning completed schemes into long-term commercial holdings.

Across Lincolnshire, we regularly finance offices (single-tenant and multi-let), retail premises (high street and out-of-town), industrial units and warehouses, mixed-use buildings with commercial and residential elements, pubs, restaurants, and leisure properties, medical and dental practices, and care homes. Each property type has specific lender criteria, and we match your Boston asset to funders with proven appetite for your sector.

For properties requiring improvement before long-term finance, we can structure a refurbishment facility or bridging loan to fund the works, followed by a refinance onto a commercial mortgage once the property is stabilised and income is flowing. This two-stage approach often achieves better long-term mortgage terms than financing an un-renovated property directly.

Commercial mortgage credit for Boston assets is competitive: Together, Aldermore, Shawbrook, and InterBay compete with the high-street banks (Barclays among them) on standard investment cases. Lenders assess debt service cover (DSCR) as closely as LTV, and adjacent products matter — a commercial bridging finance facility to acquire quickly before terming out, buy to let structures for resi-heavy assets, or a second charge to release equity without disturbing an existing first.

Commercial mortgage interest rates for Boston properties typically range from 5.5% to 8% per annum on a fixed-rate basis, or base rate plus 2-4% on variable terms. The rate depends on property type, tenant quality, lease strength, and leverage. Well-let multi-tenanted properties with strong covenants attract the keenest pricing, while single-tenant assets with shorter leases or weaker tenants carry a premium.

Arrangement fees are typically 0.5-1.5% of the facility, with valuation fees of £1,500-£5,000 depending on property complexity. Legal costs are payable for both borrower and lender solicitors. Fixed-rate terms are available from 2 to 25 years, with longer fixes providing income certainty but carrying early repayment charges if you need to exit the facility before maturity.

LTV on commercial mortgages typically ranges from 60-75%, with the maximum depending on property type and income strength. Properties with government or blue-chip tenants on long leases may achieve 75% LTV, while more marginal assets might be capped at 60-65%. The interest coverage ratio (ICR) requirement, typically 125-175%, can also limit the effective LTV where rental income is modest relative to property value.

Commercial mortgage lenders primarily assess the property's income characteristics: rental income level and sustainability, tenant financial strength (covenant), lease terms and break clauses, the weighted average unexpired lease term, and comparable evidence for re-letting if current tenants vacate. For Boston commercial properties, local market evidence of rental demand and comparable investment transactions supports your application.

Borrower assessment focuses on experience with commercial property, financial standing, and the management plan for the asset. Most commercial mortgages are made to limited companies or SPVs rather than individuals. Personal guarantees are common for smaller facilities (under £2M) but can sometimes be avoided or limited for larger, well-secured loans. The Financial Conduct Authority does not regulate most commercial lending, though some mixed-use properties with residential elements may fall within regulatory scope.

Vacant or partially vacant commercial properties can be financed, though terms will reflect the income risk. Lenders typically apply a void cost calculation and stress-test the income coverage assuming continued vacancy. Having a credible letting strategy and evidence of tenant interest helps secure finance for properties that are not fully let at the point of application.
