How long does it take to get an HMO mortgage approved?

The time taken to secure an HMO (House in Multiple Occupation) mortgage is highly variable and usually takes significantly longer than standard residential or even basic buy-to-let (BTL) mortgages. Due to the complex nature of the property, specialist underwriting requirements, and mandatory compliance checks, applicants should typically budget between 8 and 16 weeks from initial submission to final completion. However, poorly prepared applications or properties with licensing issues can extend this timeline considerably.

How Long Does It Take to Get an HMO Mortgage Approved? Understanding the Timeline

Securing a mortgage for a House in Multiple Occupation (HMO) is a necessary step for landlords looking to maximise rental yield by housing multiple unconnected tenants. Because HMO properties carry greater regulatory and management risk than standard single-family dwellings, the lending criteria are stricter, and the approval process naturally takes longer.

Understanding the detailed timeline and the potential sticking points is crucial for managing expectations and speeding up your application process.

Key Factors Influencing HMO Mortgage Speed

The duration of the approval process depends on several interdependent factors. It is rarely a straightforward 28-day turnaround often seen in simple residential cases.

Lender Type and Expertise

The choice of lender is perhaps the most significant factor affecting speed. High-street banks often approach HMO lending cautiously, relying on slower, rigid underwriting processes. Specialist HMO lenders, while often more flexible, are typically dealing with complex cases and may still require extensive due diligence.

• Specialist Lenders: Usually offer faster decisions in principle (DIP) and quicker access to specialist surveyors, but the underwriting depth remains high.
• High Street Lenders: May have longer administrative backlogs, especially when dealing with complex properties that fall outside their typical lending criteria.

Applicant Profile and Experience

Lenders place significant weight on the experience and financial standing of the applicant. If you are an experienced landlord with a clean financial history and established portfolio, the underwriter may process your case quicker than if you are a first-time HMO investor.

• First-time HMO Landlords: Will face extra scrutiny on their business plans and proposed management arrangements, potentially adding weeks to the timeline.
• Credit History: Any past credit issues, especially defaults or County Court Judgements (CCJs), will trigger deeper investigations by the underwriter, causing delays.

Property Complexity and Licensing

HMO properties require an additional layer of regulatory compliance that standard BTL properties do not. This includes adherence to local council regulations regarding room sizes, fire safety, and amenity provision. Crucially, most large HMOs require a mandatory licence, which must be secured (or demonstrably in process) before completion.

• Valuation: HMO valuations are specialist. The valuer assesses the property based on its commercial earning potential, which can take longer to arrange and complete than a standard residential survey.
• Licensing Status: Delays are extremely common if the property requires an HMO licence but the application is incomplete or pending approval from the local authority. Lenders will not complete without assurance that the property is legally compliant. You can find detailed requirements for HMO licensing on the UK government website: HMO Licence Guidance (Gov.uk).

The HMO Mortgage Application Timeline: Step-by-Step Breakdown

While timelines vary, the process generally breaks down into three distinct phases:

Phase 1: Initial Preparation and Agreement in Principle (2–4 weeks)

This phase is heavily dependent on the applicant’s preparation. Getting the right advice early is essential.

• Broker Consultation and Product Sourcing: Working with a specialist broker ensures you are matched with the right lender quickly. They will determine affordability and eligibility.
• Documentation Gathering: Providing all required personal, financial (SA302s, bank statements), and property documents (EPC certificates, existing tenancy agreements) promptly.
• Decision in Principle (DIP): The lender provides a non-binding offer based on the information provided. While a DIP might be received within days, it is only the starting point.

Phase 2: Underwriting, Valuation, and Due Diligence (4–8 weeks)

This is typically the longest and most volatile phase, as external third parties and internal lender scrutiny take place.

• Full Application Submission: Once the DIP is accepted, the full application is submitted, along with supporting documents.
• Valuation Instruction: The lender instructs a specialist surveyor. Due to the complex nature of HMOs, booking the survey and receiving the detailed report can take 2–3 weeks.
• Underwriting Review: The dedicated underwriter reviews the valuation report, checks all submitted documentation, and verifies the property’s compliance status (HMO licence status, planning permission if applicable).
• Mortgage Offer Issued: Once the underwriter is satisfied with all aspects—the applicant, the property, and the required compliance—the formal mortgage offer is issued.

Phase 3: Legal Work and Completion (2–4 weeks)

The final phase involves the legal transfer of funds and ownership.

• Conveyancing: Your solicitor (who should also be experienced in commercial property/HMO transactions) conducts searches, reviews the lease or freehold, and addresses specific conditions placed by the lender.
• Transfer of Funds: On the agreed completion date, the lender transfers the funds to the solicitor, and ownership is legally transferred.

Strategies for Speeding Up the HMO Mortgage Process

While you cannot control the lender’s internal processing times, you can significantly influence the speed of the first two phases.

1. Use a Specialist Broker

A broker who specialises in HMO finance understands the nuances of different lenders’ criteria and knows which providers are currently offering the fastest service. They can package the application perfectly the first time, preventing common delays caused by missing information.

2. Pre-empt Documentation Requests

Gathering all necessary documentation before applying is the single biggest time-saver. This checklist includes:

• Proof of identity and address (certified copies).
• Full three years’ worth of UK tax returns (SA302s and tax year overviews).
• Personal and business bank statements (typically 3–6 months).
• A detailed property schedule, including proposed or actual rent figures per room.
• Evidence of the current or pending HMO licence application status.

3. Address Property Compliance Early

Ensure that the property meets all necessary HMO standards before the valuer visits. If the valuation comes back with specific conditions related to safety or regulatory compliance, you will face delays while you arrange and document the necessary remedial works.

Even if you are purchasing a property that is already licensed, confirm the licence is transferable or that the existing landlord has correctly initiated the renewal/transfer process with the local council well in advance.

Potential Pitfalls that Cause Delays

Delays are common in HMO lending. Recognising these potential issues early can help mitigate risk:

• Inexperienced Solicitors: If your solicitor lacks experience with commercial finance or HMO requirements, they may struggle to handle the lender’s complex requirements efficiently.
• Low Valuation: If the specialist valuation comes in lower than anticipated, this can halt the process while you renegotiate the price or secure additional deposit funds.
• Lender Overload: Economic changes or unexpected surges in demand can slow down the underwriting teams at even the fastest lenders.
• Missing Financial Records: Self-employed or portfolio landlords who cannot easily provide verifiable income proof will face significant interrogation and potential hold-ups.

When dealing with specialist finance, thorough preparation is key. While 8 to 16 weeks is a typical baseline, complexity or poor organisation can push the timeline towards six months or more. Always build a buffer into your completion schedule if you are working to a contractual deadline.

People also asked

How is an HMO mortgage different from a standard BTL mortgage?

An HMO mortgage is a specialist commercial product, whereas a standard BTL mortgage is often classed as a consumer loan. HMO lending requires stricter underwriting, higher fees, and focuses heavily on the applicant’s landlord experience and the property’s compliance with mandatory local authority licensing and safety standards.

Can I get an HMO mortgage approved in less than 8 weeks?

While possible in rare, simple cases (e.g., small HMOs bought by highly experienced landlords using cash-back remortgages with familiar lenders), it is highly unlikely. The specialist valuation and mandatory legal checks typically take a minimum of six to eight weeks to complete accurately, making sub-eight-week completions very challenging.

Do HMO licences delay the mortgage process?

Yes, absolutely. Lenders require assurance that the property will be legally let. If a new HMO licence is required for the property, the lender will likely impose a condition on the mortgage offer stating that the licence must be granted or that compelling evidence of the final stages of the application must be provided before funds are released. This reliance on the local council’s speed often creates the biggest variable delay.

Do I need a bigger deposit for an HMO mortgage?

Generally, yes. Loan-to-Value (LTV) ratios are typically more conservative for HMOs due to the perceived risk. While some lenders offer 75% LTV, many specialist HMO products cap borrowing at 70% or 65%, meaning you will often require a deposit of 30% or more.

What happens if my property loses its HMO licence during the term?

If the property loses its licence, you are in breach of your planning and regulatory conditions, which often breaches the terms of your mortgage agreement. This could lead to the lender requiring immediate remediation or, in serious cases, demanding that the loan is repaid, potentially forcing you to refinance onto a different, non-HMO product.

Conclusion

The complexity inherent in financing Houses in Multiple Occupation dictates a longer approval timeframe than standard property purchases. By meticulously preparing your documentation, ensuring full compliance with HMO licensing requirements from the outset, and engaging specialist financial and legal professionals, you can minimise unnecessary delays and increase the likelihood of achieving approval within the typical 8 to 16-week window. Remember that effective management of the application process is just as important as the strength of your financial position.
