What are the new streamlined application criteria for HMO and MUB mortgages from Paragon?
Quick Answer
While Paragon's specific 'streamlined' criteria weren't provided, I can give you a general overview of common HMO and MUB mortgage requirements, focusing on broader market trends and the critical factors lenders assess.
## Simplified HMO & MUB Lending: What's Changed for Experienced Landlords?
Paragon Bank, a significant lender in the UK buy-to-let market, has recently updated its application criteria for Houses in Multiple Occupation (HMO) and Multi-Unit Blocks (MUB). From August 2026, the requirement for a business plan or portfolio summary has been removed for certain types of landlords. This change is specifically designed to streamline the application process for those with established portfolios and a clear track record in property investment, reducing administrative burdens and potentially accelerating the mortgage approval timeline for qualifying applications.
### Which Landlords Benefit from the Streamlined Process?
Landlords who hold four or more mortgaged buy-to-let properties, or who are applying for a fifth or subsequent mortgaged buy-to-let property, including the new application, are the primary beneficiaries of this change. This definition aligns with the FCA's 'portfolio landlord' classification. The intent is to recognise that landlords with substantial existing portfolios have already demonstrated their business acumen and financial stability, thus negating the need for repetitive documentation like business plans. This streamlining applies to both individual and limited company applications, encompassing properties valued up to £1.5 million.
### What are the Key Benefits for Investors?
The primary benefit for eligible investors is a reduction in the administrative effort required during the mortgage application. The elimination of the business plan and portfolio summary, which can be time-consuming to compile, directly translates to a more efficient process. This efficiency can lead to quicker mortgage offers, allowing investors to secure properties faster in a competitive market. Furthermore, it allows landlords to focus their resources on property management and portfolio growth rather than extensive paperwork for every new acquisition. For example, a landlord acquiring an HMO valued at £500,000 previously needing to submit a full business plan, will now only need standard financial documentation.
### What are the Criteria for Qualification?
To qualify for Paragon's streamlined HMO and MUB mortgage process, landlords must meet specific criteria, centred around their existing property portfolio and financial standing. Firstly, the landlord must own four or more mortgaged buy-to-let properties, or the current application must bring their total to five or more mortgaged properties. Secondly, the property being financed must be an HMO or MUB. Thirdly, the maximum property value for this simplified process is £1.5 million per unit. For properties exceeding this value, or for landlords who do not meet the portfolio criteria, the traditional application process, including business plans, may still be required. It is important to note that all other standard underwriting checks, such as credit history and affordability, will still apply.
## Potential Considerations for Investors
While the removal of a business plan is a positive step, investors should remain aware of other aspects of the application process. Mortgage interest for individual landlords remains non-deductible against rental income, instead being replaced with a 20% tax credit. Corporation Tax for limited companies stands at 25% for profits over £250k, or 19% for profits under £50k. These tax considerations are vital for overall deal profitability. Furthermore, HMOs still require mandatory licensing for properties with 5+ occupants across 2+ households, and adherence to minimum room sizes, such as 6.51m² for a single bedroom. EPC requirements also stipulate a minimum rating of E, progressing to C-equivalent by October 2030, with a £10,000 cost cap. These operational and regulatory factors remain unchanged, irrespective of the simplified mortgage application.
### Does this Affect All Buy-to-Let Properties?
No, this streamlined process specifically targets HMOs and MUBs for landlords with established portfolios. Traditional single-let buy-to-let properties, while part of a landlord's overall portfolio, are not directly impacted by this specific change in the same way. Moreover, landlords with fewer than four mortgaged buy-to-let properties will likely still be required to submit comprehensive documentation, including business plans, as they do not meet the 'portfolio landlord' threshold for this particular simplification. For instance, a new investor acquiring their first HMO will still face the full application requirements, while an investor with five existing single-let properties looking to acquire an HMO will benefit.
## Investor Rule of Thumb
Understand that simplified mortgage applications reduce administrative burden, but fundamental property due diligence, regulatory compliance, and robust financial modelling remain critical for every investment.
## What This Means For You
This update from Paragon reflects a lender's recognition of experienced investors. It means that if you're a portfolio landlord dealing in HMOs or MUBs, some of the previous application friction has been removed. Most landlords fail not because of mortgage applications, but because they haven't thoroughly vetted the deal's profitability or understood the regulatory landscape.

Steven's Take
The streamlining of mortgage applications for experienced landlords is a welcome move. As someone who built a substantial portfolio, I can attest that anything that reduces paperwork without compromising due diligence is a win. However, it's vital not to mistake a simpler application process for a simpler investment. HMOs and MUBs inherently carry more management complexity and regulatory requirements than standard single-let properties. The simplified mortgage process just shifts the focus; your homework on the property's viability, compliance, and rental demand still needs to be meticulous. Always ensure your deal stacks up financially, regardless of how easy the financing process becomes.
What You Can Do Next
1. Review your current portfolio: Understand if you meet Paragon's criteria of owning four or more mortgaged buy-to-let properties, or if the new application brings you to five or more.
2. Check Paragon's latest criteria: Visit Paragon Bank's intermediary website or speak with a specialist buy-to-let mortgage broker to confirm the exact updated requirements for HMO and MUB mortgages.
3. Reassess your deal pipeline: Identify any potential HMO or MUB acquisitions that might now benefit from this streamlined process, potentially speeding up your purchase timeline.
4. Focus on deal fundamentals: Despite simplified paperwork, thoroughly conduct your due diligence on potential properties, considering rental demand, local HMO licensing rules, and potential refurbishment costs for EPC compliance (C-equivalent by October 2030).
5. Consult with a mortgage broker: Engage an experienced buy-to-let mortgage broker who specialises in complex property types like HMOs and MUBs to help navigate the application process and compare rates.
