For higher-rate taxpayers, the cheapest buy-to-let rate is rarely the cheapest structure.
Limited company mortgages usually price a little higher — but how the rental profit is taxed often matters more than the headline rate.

How your case is assessed
How lenders assess limited company buy-to-let
Company BTL lending is underwritten on the property's income and the people behind the company — the SPV itself has no trading history to assess.
The company structure itself
Most lenders want a special purpose vehicle set up for property, with the right SIC code and no trading activity. A general trading company narrows the panel sharply.
Rental coverage at the stress rate
Rent typically needs to cover 125–145% of the payment at a stress-test rate. Company borrowers are often assessed at the lower ratio because interest is fully deductible — which can help borrowing capacity.
Directors, shareholders and guarantees
Lenders credit-check the directors personally and usually require personal guarantees. Adding a non-borrowing shareholder can quietly remove lenders from the panel.
Rate, fees and total cost
SPV rates and arrangement fees usually sit above personal BTL. The question is never the rate alone — it's the rate plus fees against the tax you keep.
You don't need to guess whether an SPV is right — we model both structures against your tax position before any hard search.
Specialist insight
Not every lender treats a company purchase the same way
New SPV · first company purchase · extra shareholders
Higher challenge
Narrower panel · personal guarantees expected · trading companies and non-borrowing shareholders remove lenders before the application starts.
Clean SPV · strong coverage · experienced landlord
More lender choice
Broader specialist SPV panels · sharper pricing tiers · clearer path when the company, rent and deposit all line up.

“Landlords come to us with a cheaper personal rate on screen. Once the tax on the rent is included, the company deal is often the cheaper decision — and the rate was never the point.”

Lived experience
Mistakes we repeatedly see
Not theory — patterns that keep showing up when landlords incorporate because they heard it was tax-efficient, without modelling their own position.
Comparing rates instead of outcomes
A personal deal half a percent cheaper can still leave a higher-rate taxpayer worse off once rental profit is taxed as income. Model the net, not the headline.
Assuming incorporation is always better
For a basic-rate taxpayer with one or two properties, personal ownership is often simpler and cheaper. Company ownership adds accountancy, filing and extraction costs.
Forgetting that moving a property in is a sale
Transferring a personally-owned property to your own company usually triggers Stamp Duty and a Capital Gains Tax event. That cost decides more cases than the rate does.
Setting up the company wrong first
Trading SIC codes, extra shareholders or a holding structure added for convenience can remove most of the SPV panel. Get the structure right before the application.
Ignoring how you get money out
Profit inside a company is taxed again when it comes out as dividends or salary. If you need the rent to live on today, the tax case is much weaker.
Real client scenarios
How we've helped company landlords
Based on genuine cases we've helped with. Personal details have been changed to protect privacy.
Higher-rate taxpayer — the cheaper rate was the costlier route
- 40% taxpayer
- New SPV
- Tax modelled
- Company won
Situation
Higher-rate taxpayer buying a second rental, holding a personal BTL quote from a comparison site.
Challenge
The personal rate looked clearly cheaper, but no one had modelled tax on the rental profit or the restricted interest relief.
What changed
Set up a clean SPV with the right SIC code, then placed the purchase with a specialist company lender at a slightly higher rate.
Outcome
Marginally more interest, materially more retained profit — and a structure that scales to the next purchase.
Why it worked
We compared net position, not headline rates. The comparison-site winner was the expensive long-term answer.
SPV set up wrong — fixed before the application
- Trading SIC code
- Extra shareholder
- Panel restored
- Placed once
Situation
Landlord had already incorporated using a general trading SIC code, with a family member added as a shareholder.
Challenge
Most SPV lenders wouldn't look at the company as constituted — an application would have burned a hard search for nothing.
What changed
Corrected the company's SIC code and shareholding position before applying, then matched a single specialist lender.
Outcome
One clean application instead of a trail of avoidable declines.
Why it worked
The barrier was the company, not the borrower. Fixing the structure first put the whole panel back in play.
Basic-rate landlord — advised to stay personal
- Basic-rate taxpayer
- Single property
- Needed the rent
- Stayed personal
Situation
Landlord assumed a company was automatically the smarter option for a first rental property.
Challenge
As a basic-rate taxpayer drawing the rent as income, incorporation added cost and complexity without a tax gain.
What changed
Modelled both routes honestly and recommended personal ownership with a mainstream BTL lender.
Outcome
Cheaper borrowing, simpler admin, no unnecessary company overheads.
Why it worked
The right answer was the one that suited the client's tax band — not the one the internet was recommending.

Advisory promise
When we might tell you to wait
We won't always tell you to apply today.
We may advise waiting where the company needs restructuring before lenders will look, where your tax position doesn't actually justify incorporation, or where moving an existing property into a company would cost more in Stamp Duty and Capital Gains Tax than the tax saving recovers.
If a different structure or a short delay would meaningfully improve your long-term position, we'll say so before another footprint goes on your file. We give advice — not just applications.

Common questions about limited company buy-to-let
Our promise
What we'll never do
- Tell you to apply if it won't work
- Send applications everywhere
- Recommend borrowing beyond your budget
- Hide bad news
We don't sell the cheapest BTL rate. We help you understand which ownership structure leaves you better off.
Find out which structure fits
Tell us your tax position, the property and the rent — we'll model personal against limited company before you commit to either.
We don't recommend a lender until we understand your tax band, how long you plan to hold the property and whether an SPV genuinely improves your position.
Moving a property into a company later usually means Stamp Duty and Capital Gains Tax. A conversation now is far cheaper than restructuring in three years.
