Avoid Costly Mistakes When Building Your Portfolio
If you’re planning to invest in buy-to-let properties through a limited company, setting up an SPV (Special Purpose Vehicle) is a smart move. It can make your portfolio more tax-efficient, simplify mortgage applications, and help separate personal and business finances. But setting it up properly is essential — and that’s where tailored SPV mortgage advice makes all the difference — (Click here to learn more).
Here’s a step-by-step guide to help you avoid common pitfalls and lay strong foundations for your SPV.
1. Decide if an SPV is right for your investment goals
SPVs are limited companies created solely for property investment. They’re especially useful for landlords building a portfolio or planning to expand in the future. Whether you’re just starting out or transitioning from personal ownership, it’s crucial to understand how lenders assess SPVs differently. That’s why seeking SPV mortgage advice early can save you both time and money.
👉 Outcome: Gain clarity and control over your property investments while laying the groundwork for long-term tax efficiency.
2. Choose the correct SIC code
Lenders expect your SPV to use a specific Standard Industrial Classification (SIC) code linked to property letting. The most commonly accepted codes include:
68100 – Buying and selling of own real estate
68209 – Other letting and operating of own or leased real estate
Stick with property-only codes. Don’t be tempted to include unrelated business activities like consulting, construction, or property development unless you’ve discussed this with your broker or accountant.
👉 Outcome: Avoid lender rejections by ensuring your company is properly classified for mortgage eligibility.
3. Common Mistakes to Avoid
Too many landlords rush through the SPV setup process — and it can cost them later in tax, lending issues, or compliance. Here are some of the most common (and costly) mistakes I see:
❌ Choosing the wrong SIC code – It confuses lenders and can result in declined applications.
❌ Mixing personal and business finances – This undermines the SPV’s legal structure and complicates tax.
❌ Using a trading company instead of a clean SPV – A company with other activities or trading history is far less attractive to lenders.
❌ Not taking tax advice upfront – Stamp duty, capital gains, or dividend planning can trip you up later.
❌ Naming the company poorly – Overly personal or vague names can appear unprofessional to lenders.
Lenders vary in their SPV requirements. Some require minimum ICRs (Interest Coverage Ratios), experience, or specific ownership structures. That’s why working with a specialist in mortgages for portfolio landlords helps keep your application on track — Click here to learn more
👉Outcome: Set yourself up for success and avoid the pitfalls that can stall mortgage applications or lead to compliance issues.
4. Pick a relevant company name
Choose a name that clearly reflects your property investment business. Lenders prefer straightforward names over overly creative ones. Including “Properties” or “Holdings” can be helpful.
👉 Outcome: Make your business appear credible and focused when applying for mortgages or dealing with accountants.
5. Appoint directors and shareholders
Most lenders prefer the directors and shareholders to be the same individuals – and ideally, you want minimal cross-ownership with other businesses. Keep the structure clean and simple to make mortgage applications easier.
👉 Outcome: Align your ownership with your long-term tax planning and estate strategy.
6. Open a dedicated business bank account
Once your company is registered, open a business bank account in the SPV’s name. This helps keep your finances separate, and you’ll need it when applying for mortgages or receiving rental income.
👉 Outcome: Stay compliant and make financial tracking easier come tax season.

7. Set up your accounting and tax structure
Appoint an accountant who understands property investment through SPVs. They’ll help you manage:
- Corporation Tax
- Annual returns
- Dividend structure
- Mortgage interest relief
Keeping your books clean is crucial for both compliance and funding.
👉 Outcome: Minimise tax, reduce admin stress, and improve your bottom line.
8.Notify your accountant early
Before buying any property, run your plans past your accountant. They can help you make tax-efficient decisions, and flag any issues early on – particularly around stamp duty, capital gains tax, or ownership splits.
👉 Outcome: Avoid penalties and start your business with the right financial systems in place.
9. Understand lender requirements for SPVs
While many buy-to-let lenders now offer limited company mortgages, most prefer SPVs that have no trading history or involvement in unrelated business activities. A clean, property-focused company structure makes you more attractive to lenders.
One of the most common reasons for mortgage refusals is failing to meet rental income requirements — specifically the Interest Coverage Ratio (ICR). If your portfolio doesn’t generate enough rental income, your application could be declined — Learn more about how this works.
Lender criteria vary significantly. Some focus on loan-to-value (LTV) ratios, property types, or rental stress tests. Others assess the company structure or require a minimum ICR, which depends on whether you’re a basic-rate or higher-rate taxpayer.
This is where working with a specialist broker becomes essential — especially if you own multiple properties. I provide tailored support on SPV and Limted Company Buy-to-Let Mortgages, helping you meet the right criteria and secure the most suitable deals — Click here to learn more.
👉 Outcome: Improve your chances of mortgage approval by ensuring your SPV meets lender expectations from day one.
10. Secure a mortgage with a specialist broker
Don’t assume your usual high street lender will help – most SPV buy-to-let mortgages are accessed through specialist brokers. I work with over 170 lenders, including those who cater specifically to SPVs, portfolio landlords, and limited companies.
If you’re unsure how lenders assess your affordability, read my mortgage stress testing guide to see how your application might be scrutinised.
👉 Outcome: Secure better rates, borrow more, and benefit from specialist underwriting support.
11. Keep your SPV compliant
Once up and running, your SPV must submit:
- Annual accounts to Companies House
- Corporation Tax returns to HMRC
- Confirmation statements
Failure to keep up with admin can affect your credit profile and mortgage eligibility.
👉 Outcome: Stay on the right side of Companies House and HMRC — and avoid costly fines or delays.
12. Keep personal and business finances separate
Never mix SPV income with personal finances. All rental income, expenses, and mortgage payments should flow through the company’s bank account. It’s cleaner, simpler, and keeps your liability limited.
👉 Outcome: Stay compliant, avoid confusion, and maintain a clean record for mortgage lenders and HMRC.
