Setting Up an SPV for HMO Mortgages: Step-by-Step Guide

If you have decided that buying your HMO through a limited company makes financial sense — and for many higher-rate taxpayers, it does — the next question is how to actually set one up. The good news is that forming an SPV (Special Purpose Vehicle) for property investment is straightforward. The bad news is that getting the details wrong can cause problems with mortgage lenders down the line.

This guide walks through the entire process of setting up an SPV specifically for HMO mortgage purposes, from choosing the right company structure to the SIC codes lenders expect to see. If you are still weighing up whether an SPV is the right move, read our SPV vs personal name comparison first.

What Is an SPV and Why Use One for HMOs?

An SPV is a limited company set up specifically to hold property investments. It is a separate legal entity from you personally, which means:

The company owns the property, not you
Rental income is the company's income, taxed at corporation tax rates
Mortgage interest is a fully deductible business expense (unlike personal ownership post-Section 24)
Your personal assets are protected by limited liability

For HMO investors, the SPV structure is particularly attractive because HMOs generate higher rental income than single-let properties, which means the Section 24 mortgage interest restriction hits harder when you own personally. An SPV sidesteps this entirely.

Corporation tax in 2026 is 19% for profits up to £50,000 and 25% for profits over £250,000, with marginal relief in between. Compare that to personal income tax at 40% or 45% for higher-rate and additional-rate taxpayers, and the advantage is clear — provided you structure things correctly from the start.

Step 1: Incorporate Your Company

Setting up an SPV begins with incorporating a limited company through Companies House. You can do this yourself online at gov.uk for £12, or use a formation agent for £20-£100 if you want additional services like a registered office address.

Key Decisions at Incorporation

Company name: Choose something professional that reflects your property business. Many investors use their surname plus "Properties" or "Investments" — for example, "Wallace Property Holdings Ltd". Avoid anything misleading or too generic.

Registered office address: This is a public record. You can use your home address, your accountant's address, or a formation agent's address. Many investors prefer not to use their home address for privacy reasons.

Directors: You must have at least one director who is a natural person (not another company). You can be the sole director, or you can appoint additional directors — such as a spouse or business partner. Some lenders require all directors to be named on the mortgage application, so keep the structure simple.

Shareholders: You and any co-investors will typically be shareholders. Share structure matters for tax planning — discuss the allocation with your accountant before incorporating, as changing it later can trigger tax charges.

Articles of association: The standard Model Articles are fine for most property SPVs. Only consider bespoke articles if you have specific requirements around shareholder agreements or profit distribution.

Step 2: Get the SIC Codes Right

This is where many new investors make mistakes that cause problems months later when they apply for a mortgage.

SIC (Standard Industrial Classification) codes tell Companies House and lenders what your company does. For a property SPV, you need to include the correct codes from day one. The most important ones are:

68100 — Buying and selling of own real estate
68201 — Renting and operating of own or leased real estate (excluding Housing Association)
68209 — Other letting and operating of own or leased real estate

Most HMO mortgage lenders expect to see 68100 and 68209 as a minimum. Some also want 68201. Including all three covers your bases and signals clearly that the company exists to buy, own, and let property.

Do not add unrelated SIC codes. If your company has codes for consulting, construction, or any non-property activity, some lenders will either decline the application or require additional due diligence. Keep the SPV clean and focused on property.

You can add or change SIC codes after incorporation via the annual confirmation statement, but it is far easier to get them right at the start.

Step 3: Open a Business Bank Account

Your SPV needs its own bank account, separate from your personal finances. This is not optional — it is a legal requirement for a limited company, and lenders will want to see that the business operates properly.

Opening a business bank account for a property SPV is straightforward. Most high-street banks and digital banks (Starling, Tide, Monzo Business) offer accounts suitable for property companies. You will need:

Certificate of incorporation
Proof of identity for all directors and persons of significant control
Confirmation of the company's activities

Some banks are faster than others. Digital banks typically open accounts within days, while high-street banks can take several weeks. Start this process early — you do not want a delayed bank account holding up your mortgage completion.

Step 4: Appoint an Accountant

A property-specialist accountant is not optional for an SPV — it is essential. Your accountant will handle:

Annual accounts filed with Companies House
Corporation tax returns filed with HMRC
VAT registration if applicable (unlikely for residential HMOs)
Dividend planning to extract profits tax-efficiently
Payroll if you draw a salary from the company

The cost of a specialist property accountant for a small SPV is typically £500 to £1,500 per year, depending on the complexity of your portfolio. This is a deductible business expense.

Choose an accountant who understands property investment specifically. General practice accountants often miss property-specific tax reliefs and structuring opportunities that can save thousands over time.

Step 5: Understand How SPV Mortgages Work

SPV mortgages are structured differently from personal buy-to-let mortgages in several important ways.

Personal Guarantees

Almost all SPV mortgage lenders require personal guarantees from the directors. This means that while the company owns the property, you are personally liable for the mortgage debt if the company defaults. Limited liability protects you from most business debts, but mortgage lenders carve out an exception through personal guarantees.

This is standard practice and should not put you off SPV ownership — but it does mean you should not view the SPV as a way to shield yourself from mortgage obligations.

Deposit Requirements

SPV HMO mortgages typically require a minimum 25% deposit, compared to 20-25% for personal name purchases. Some lenders require 30% for limited company HMO lending. The slightly higher deposit reflects the additional perceived risk of lending to a company rather than an individual.

For a full breakdown of deposit requirements, see our HMO mortgage deposit guide.

Interest Rates

SPV mortgage rates are typically 0.5% to 1% higher than personal name equivalents at the same LTV. This gap has narrowed in recent years as more lenders have entered the limited company buy-to-let market, but it still exists.

However, the net cost — after accounting for full mortgage interest relief at corporation tax rates — is often lower for higher-rate taxpayers buying through an SPV. This is the calculation that matters, not the headline rate. For current rates, check our HMO mortgage rates page.

Lending Criteria

Lenders assess SPV applications based on:

The rental income of the property (same as personal mortgages)
The personal income and credit history of the directors (via personal guarantees)
The company's existing portfolio and financial position
The company's trading history (new SPVs are accepted by most specialist lenders)
The SIC codes registered with Companies House

New SPVs with no trading history are accepted by the majority of specialist buy-to-let lenders. This is not a barrier — lenders understand that SPVs are typically set up specifically to acquire property.

Step 6: Get Your Mortgage Agreement in Principle

Before making offers on properties, secure an agreement in principle (AIP) from a lender who is comfortable with SPV HMO lending. Not all buy-to-let lenders offer SPV products, and not all SPV lenders are comfortable with HMOs — so you need a lender that ticks both boxes.

The AIP process for an SPV is similar to a personal application but requires additional documentation:

Certificate of incorporation
Memorandum and articles of association
Details of all directors and shareholders
Company bank statements (if the SPV has been trading)
Personal identification and proof of address for all directors
Details of any existing property portfolio (personal and company)

Working with a comparison site that specialises in HMO mortgages makes this process significantly smoother, as they can identify which lenders suit your specific SPV setup without wasting time on applications that will not progress.

Common Mistakes to Avoid

Adding Too Many SIC Codes

As mentioned above, adding non-property SIC codes — even if your company might do other things in future — creates problems with mortgage lenders. Keep the SPV focused on property.

Using an Existing Trading Company

Some investors try to buy HMOs through an existing company that trades in another sector (consulting, construction, etc.). Most mortgage lenders will decline this. They want a clean SPV with property-only activities. Set up a new company for your HMO investments.

Not Setting Up the Share Structure Correctly

The initial share allocation affects dividend distribution, tax planning, and future sale or transfer of the company. Get advice from your accountant before incorporating. Changing the share structure after the company is trading can trigger capital gains tax or stamp duty charges.

Ignoring the Company's Credit Profile

Your SPV will develop its own credit profile over time. Paying bills on time, maintaining the business bank account in good order, and filing accounts promptly all contribute to this. A well-maintained company credit profile can improve your mortgage options as you grow your portfolio.

Forgetting Annual Filing Obligations

Limited companies must file:

Annual confirmation statement with Companies House (due within 14 days of the anniversary of incorporation)
Annual accounts with Companies House (due within 9 months of the financial year end)
Corporation tax return with HMRC (due within 12 months of the financial year end)

Missing these deadlines can result in fines, and repeated failures can lead to the company being struck off — which creates serious problems if it holds mortgaged property.

The Costs of Running an SPV

Understanding the ongoing costs helps you decide whether the SPV structure is worthwhile for your situation.

Cost	Typical Amount	Frequency
Company incorporation	£12-£100	One-off
Accountancy fees	£500-£1,500	Annual
Companies House confirmation statement	£13	Annual
Business bank account	£0-£10/month	Monthly
Registered office service (if used)	£50-£150	Annual
Legal fees for mortgage	£500-£1,500	Per purchase

Total ongoing costs for a simple SPV are typically £600 to £2,000 per year. This is easily justified if the corporation tax savings on your HMO income exceed this amount — which they will for most higher-rate taxpayers with even a single HMO.

SPV Setup Checklist

Use this checklist to make sure you have covered everything before applying for your HMO mortgage:

[ ] Incorporate the company with correct SIC codes (68100, 68201, 68209)
[ ] Register at a suitable address
[ ] Open a business bank account
[ ] Appoint a property-specialist accountant
[ ] Set up the share structure (get accountant advice first)
[ ] Register for corporation tax with HMRC (automatic after incorporation, but verify)
[ ] Gather personal ID documents for all directors
[ ] Secure a mortgage agreement in principle through a specialist comparison service
[ ] Ensure directors' personal credit files are clean and up to date

Frequently Asked Questions

Can I transfer an existing HMO from my personal name into an SPV?

Technically, yes — but it is treated as a sale. You will potentially owe stamp duty land tax on the transfer, capital gains tax on any increase in value since you bought it, and there will be legal and mortgage fees. For many investors, the costs of transfer outweigh the benefits. It is usually more tax-efficient to buy future properties through the SPV and retain existing ones in your personal name. Take specific advice from your accountant.

Do I need a separate SPV for each property?

No. Most investors hold multiple properties within a single SPV. This is simpler and cheaper to administer. However, some investors use separate SPVs for asset protection — if one property encounters serious problems, it does not affect the others. Your accountant can advise on the best approach for your portfolio size and risk tolerance.

How long does it take to set up an SPV?

Company incorporation takes minutes online and is usually confirmed within 24 hours. Opening a bank account takes a few days to a few weeks. The whole process from start to mortgage-ready is typically two to four weeks.

Will lenders accept a brand new SPV with no accounts?

Yes. The majority of specialist buy-to-let lenders accept newly incorporated SPVs. They assess the application based on the property's rental income and the directors' personal profiles. You do not need a trading history.

Can I be a director of multiple SPVs?

Yes, there is no limit. However, being a director of multiple companies creates additional disclosure requirements on mortgage applications, and some lenders may want to understand the full group structure. Keep things as simple as your portfolio size allows.

What to Do Next

Once your SPV is set up and your bank account is open, you are ready to start looking at HMO deals and securing finance.
