Buy to Let Through a Limited Company or Personally: Which Is Right for You?

If you’re buying a buy-to-let property, choosing between personal ownership and a limited company comes down to your tax position, mortgage costs, and long-term plans. Higher-rate taxpayers and landlords looking to scale often benefit from using a limited company, while basic-rate taxpayers buying a single property may find personal ownership simpler and cheaper. The right structure should be decided before you buy, as changing it later can be costly and complex.

If you are thinking about buying a buy to let property, one of the biggest decisions you will face is whether to buy it in your personal name or through a limited company.

There is no universal right answer. Anyone telling you otherwise is oversimplifying a decision that can affect your tax position, borrowing power, mortgage costs, and long-term plans.

As mortgage brokers, we see landlords get this wrong all the time, usually because they decide after buying, not before.

This guide explains how the decision really works, what lenders look at, and how we help landlords choose the right structure based on their goals, not generic rules.

Limited Company vs Personal Ownership: What’s the Actual Difference?

At a high level, the difference comes down to who owns the property and how the income is taxed.

Buying personally

  • You own the property in your own name
  • Rental income is taxed as personal income
  • Capital gains tax applies when you sell
  • Mortgage interest relief is restricted under Section 24

Buying through a limited company

  • The company owns the property
  • Profits are taxed under corporation tax rules
  • Mortgage interest is fully deductible
  • Additional tax applies if you take profits out personally

From a lender’s perspective, these are two completely different types of mortgage, with different criteria, rates, and deposits.

The Question We Always Ask First

Before we talk about tax or mortgage rates, we ask one simple question:

What are you trying to build?

Are you:

  • Buying one property for supplementary income?
  • Planning to grow a portfolio over time?
  • Already a higher rate taxpayer?
  • Reinvesting profits rather than living off them?

Your answers dictate the structure. Not headlines. Not forums. Not what your mate did.

How Section 24 Actually Affects Landlords

Section 24 is one of the main reasons limited companies became popular.

In plain English, if you own a buy to let property personally, you can no longer deduct your full mortgage interest from rental income. Instead, you receive a basic rate tax credit.

This impacts higher and additional rate taxpayers the most.

Simple example

  • Rental income: £18,000 per year
  • Mortgage interest: £10,000 per year

Personally owned:

  • You are taxed on the full £18,000
  • You only receive a limited tax credit on interest

Limited company:

  • The £10,000 interest is deducted as a cost
  • Tax is paid on the remaining profit

This difference alone can change whether a property stacks up long term.

We do not give tax advice, but we see the real-world impact of this every day when lenders assess affordability and clients assess viability.

Case Study 1: Limited Company Buy to Let

Structure: SPV Limited Company
Property price: £285,000
Deposit: £71,250 (25%)
Mortgage: £213,750
Rent: £1,450 per month
Tax band: Higher rate taxpayer

This client already owned property personally and wanted to scale to five plus units.

Buying personally would have pushed them further into higher rate tax and restricted cash flow. A limited company allowed:

  • Full mortgage interest offset
  • Profits retained for reinvestment
  • Cleaner long-term structure for portfolio growth

Mortgage rates were higher than personal buy to let, but the overall strategy made financial sense.

Case Study 2: Personal Name Buy to Let

Structure: Personal ownership
Property price: £190,000
Deposit: £47,500 (25%)
Mortgage: £142,500
Rent: £950 per month
Tax band: Basic rate taxpayer

This was a first buy to let purchase with no immediate plans to expand.

Buying personally gave:

  • Lower mortgage rates
  • Simpler setup
  • Less ongoing administration
  • No immediate tax pressure

In this case, a limited company would have added cost without meaningful benefit.

Mortgage Differences You Need to Know About

This is where a lot of blogs fall short.

Personal buy to let mortgages

  • Lower interest rates
  • More lender choice
  • Often lower fees
  • Simpler underwriting

Limited company buy to let mortgages

  • Higher rates and fees
  • Usually 25 percent deposit minimum
  • Personal guarantees required
  • Specialist lenders only

Limited company borrowing is not worse. It is just different. You need to know that the mortgage cost is part of the decision, not an afterthought.

A Simple Rule of Thumb We Use

This is not advice. It is a starting point.

  • Higher rate taxpayer planning to scale: Limited company often makes sense
  • Basic rate taxpayer buying one property: Personal ownership often works better
  • Unsure or mid-transition: Speak to a broker before committing

The worst position is buying personally, then realising a limited company would have been better, because moving properties later is expensive and messy.

Common Mistakes We See Landlords Make

  • Choosing structure based on tax headlines alone
  • Not checking lender criteria before setting up a company
  • Assuming limited company mortgages are unavailable or impossible
  • Buying first and asking questions later
  • Mixing personal and company strategies without planning

Most of these mistakes are avoidable with a short conversation early on.

Should You Speak to a Broker Before Deciding?

Yes, if:

  • You are a higher rate taxpayer
  • You want to build a portfolio
  • You already own property personally
  • You are unsure which structure suits your plans
  • You want clarity before making a commitment

A broker looks at:

  • Mortgage availability
  • Real borrowing numbers
  • Deposit requirements
  • Long-term flexibility

That clarity often saves far more than it costs.

Final Thought

Buying a buy to let property through a limited company is not automatically better. Buying personally is not outdated. The right choice depends on you, not the internet.

The biggest mistake landlords make is treating this as a tax-only decision or a mortgage-only decision. It is both.

If you are thinking about buying a buy to let property and want to get the structure right from day one, speak to a mortgage broker before you buy, not after.
