Understanding the Article 4 Area
An Article 4 area is a designated zone where additional planning controls are in place to manage the conversion of residential properties into HMOs (Houses of Multiple Occupancy). This is often done to prevent over-saturation of HMOs in certain neighborhoods.
Current Interest Rates for HMO Mortgages
Interest rates for HMO mortgages can vary depending on several factors, including the lender, the property’s location, and the borrower’s creditworthiness. It’s essential to get quotes from multiple lenders to compare rates and find the best deal.
- 2 year fixed rate of 4.59% – No C4 certificate required (No certificate of lawful use)
- 5 year fixed rate of 5.14% – No C4 certificate required (No certificate of lawful use)

The Lack of a Certificate of Lawful Use
A Certificate of Lawful Use (CLU) is a document that confirms that a property is being used lawfully. In the case of an HMO in an Article 4 area, obtaining a CLU can be challenging, especially if the property has been used as an HMO for a significant period without planning permission.
Establishing Lawful Use Through Sufficient History
Despite the lack of a CLU, it’s possible to establish lawful use based on sufficient historical evidence. This typically involves providing documentation such as:
- Tenancy agreements: Contracts that demonstrate the property has been rented out as an HMO.
- Council tax records: Evidence of the property being assessed as an HMO for council tax purposes.
- Utility bills: Statements showing the property’s consumption patterns consistent with an HMO.
Mortgage financing for HMOs in Article 4 Areas
While many lenders are hesitant to provide mortgages for HMOs in Article 4 areas, it’s not impossible. By demonstrating lawful use through sufficient historical evidence, you can increase your chances of securing mortgage financing.
Avoiding Cash Purchases and Bridging Loans
A cash purchase can be a significant financial burden, and bridging loans often come with higher interest rates. By working with a specialist lender or mortgage broker, you can explore alternative financing options that may be more suitable for your circumstances.
Key Considerations When Purchasing an HMO in an Article 4 Area:
- Thorough due diligence: Ensure that the property has a strong history of being used as an HMO.
- Legal advice: Consult with a solicitor experienced in property law, particularly in relation to HMOs and Article 4 areas.
- Specialist lenders: Seek out lenders who specialise in HMO financing and understand the unique challenges associated with Article 4 areas.
By carefully considering these factors and working with experienced professionals, you can successfully purchase an HMO in an Article 4 area without a Certificate of Lawful Use while avoiding the need for a cash purchase or expensive bridging loan.
