A commercial mortgage for buy-to-let purposes is a loan secured against a rental property, where the expected rental income forms part of the affordability assessment. This type of finance suits landlords and property investors purchasing or refinancing rental property through a business entity, whether as an individual or via a limited company. At £150,000, the loan amount sits comfortably within most lenders' appetite for single buy-to-let investments.
Comparing buy-to-let lenders goes well beyond headline rates. Loan-to-value caps determine your deposit requirement and vary between lenders. Most will stress-test rental income at 125% to 145% of mortgage interest, though calculation methods differ. Whether you apply personally or through a limited company affects both product availability and tax treatment. The type of property and tenant profile can also narrow your lender options at the £150,000 level.
Important note:
Funding Agent
Published loan rangeFrom £10,000 to up to £1,000,000
Rate typeInterest from 6.8% annually
Why it is included:It is included because many business owners need to compare several finance routes before choosing where to apply.
Funding Agent can help businesses compare suitable options across a lender panel, especially when eligibility depends on turnover, sector, trading history, credit strength and available documents.
Best use case: When the borrower wants to avoid applying to one lender at a time.

Why it stands out
- Useful when a business wants to compare lender fit rather than guess which lender to apply to first.
- Can help position the application around the funding purpose, trading profile and available documents.
- Works well as a conversion route for readers who are unsure whether a direct lender will approve a larger unsecured facility.
Need to know
- Funding Agent is a broker, not a lender.
- The lender, not Funding Agent, sets the final rate, term, fees and approval decision.
- The best match may be unsecured, secured, revolving credit, invoice finance or another product depending on the case.
Expert take
Funding Agent is a useful honourable mention for business owners who want to compare lender options before submitting a full application. A larger unsecured loan is not always approved by the first lender a business finds, so understanding lender fit early can reduce wasted time and avoid unnecessary declines.

Commercial Mortgage Calculator
How LTV and rental yield shape a £150,000 buy-to-let application
Buy-to-let lenders at the £150,000 level assess two main factors: the property's valuation and its projected rental income.
Loan-to-value caps vary across the market. Brightstar offers up to 100% LTV, so a property valued at £150,000 could be fully funded. Offa caps LTV at 80%, meaning a £30,000 deposit on a £150,000 purchase. Together Money and MT Finance sit at 75% and 70% respectively, requiring larger deposits but often offering more competitive monthly rates.
Lenders also apply an interest cover ratio, typically 125% to 145%, to ensure rental income comfortably covers mortgage payments. On a £150,000 property generating £750 monthly rent, a lender charging 5.5% annually on interest-only would need roughly £688 to meet a 125% cover ratio.
A surveyor's valuation determines the final borrowing figure, not the purchase price, so landlords should factor in a conservative valuation when planning a £150,000 buy-to-let purchase.
Personal ownership versus limited company for £150k buy-to-let finance
Landlords arranging £150,000 in buy-to-let finance must decide whether to borrow personally or through a limited company, often a special purpose vehicle (SPV).
Borrowing via an SPV has become more common since the restriction of mortgage interest tax relief for individual landlords. Lenders on this list that work with limited companies include Offa, Together Money, and MT Finance, though most also accept individual applicants. A key difference is that limited company applications nearly always require a personal guarantee. One Stop Business Finance, Inhale Capital, Brightstar, NatWest, HSBC, and Virgin Money all confirm personal guarantees are required.
Personal borrowing may suit landlords with one or two properties and simpler tax affairs. Limited company borrowing typically suits portfolio landlords seeking to ring-fence liabilities and manage tax more efficiently. Some lenders charge slightly higher rates for limited company buy-to-let mortgages, so comparing both routes on a £150,000 application is worth the effort.
Comparing short-term and long-term rates on a £150,000 buy-to-let mortgage
Buy-to-let finance at £150,000 spans short-term bridging and long-term mortgages, with very different rate structures.
Short-term lenders charge monthly rates. Inhale Capital publishes rates from 1.05% to 1.3% per month. MT Finance sits between 0.89% and 1.05% per month. One Stop Business Finance ranges from 1.6% to 3% per month. These products suit auction purchases, refurbishments, or fast completions, with terms running 3 to 18 months.
Dedicated buy-to-let mortgage products use annual rates and longer terms:
| Buy-to-Let Product | Rate Type | Rate Range | Max LTV |
|---|---|---|---|
| Offa Buy-to-Let | Annual | 5.9% – 7.5% | 80% |
| Together Money BTL | Monthly | 0.55% – 1.5% | 75% |
| MT Finance | Monthly | 0.89% – 1.05% | 70% |
Traditional banks sit in wider bands. NatWest and Virgin Money both range from 4.5% to 10.5% annually, with terms up to 25 years. Barclays stretches from 8.5% to 14.9% annually. Landlords funding a £150,000 buy-to-let should match the product term to their investment strategy.
Practical steps to securing competitive £150,000 buy-to-let terms
Landlords targeting a £150,000 buy-to-let mortgage can take several practical steps to access better rates and terms.
First, the deposit matters. With LTV limits ranging from 70% at MT Finance to 100% at Brightstar, a larger deposit opens up more lenders and typically earns lower rates. A 25% deposit on a £150,000 property equals £37,500 and brings most lenders on this list into reach.
Second, check minimum loan thresholds. One Stop Business Finance requires a minimum facility of £100,000. Offa starts at £80,000. Virgin Money begins at £30,000. A £150,000 application clears all of these minimums.
Third, expect to provide a personal guarantee if applying through a limited company. Most lenders on this list require one regardless of the borrowing structure.
Finally, prepare your rental evidence. Lenders want tenancy agreements, rental statements, and proof of projected yields. A well-documented £150,000 application moves faster and attracts sharper pricing.
