Unenforceable HMO mortgage rules?

Many lenders require that all occupants of Houses in Multiple Occupation (HMOs) be on a single joint Assured Shorthold Tenancy (AST) rather than having individual ASTs per room. This article explores whether such a requirement is enforceable, particularly in light of the Renters’ Rights Act, and considers the implications for landlords managing HMOs.

Understanding the Joint AST Requirement for HMOs

Most mortgage lenders insist that landlords let HMOs under one joint AST, meaning all tenants sign one agreement collectively. This contrasts with the alternative approach where each tenant holds a separate AST for their individual room. Lenders often justify this rule by citing the ease of managing the tenancy and the ability to take action against all tenants simultaneously in the event of mortgage default.

Potential Issues with Joint ASTs

There are several concerns regarding the fairness and practicality of joint ASTs for HMOs:

• Joint and Several Liability: All tenants on a joint AST are typically jointly and severally liable for rent arrears, damages, and repairs. This means one tenant could be held responsible for the actions or debts of another, even if they are strangers sharing the property.
• Guarantor Obligations: Guarantors may be required to cover liabilities for the entire HMO, including tenants they have never met. This can be a significant and arguably unfair burden.
• Tenant Replacement Difficulties: Swapping out individual tenants becomes more complicated under a joint AST. It often requires agreement from all existing tenants or a “committee” decision, leading to increased administrative work and potential delays.

Enforceability and Legal Considerations

Given these issues, questions arise about whether lenders can enforce the single joint AST rule, especially considering recent tenant protection legislation such as the Renters’ Rights Act. This Act aims to strengthen tenant rights and may challenge tenancy arrangements that impose unfair responsibilities or obligations on tenants.

While lenders might argue that a joint AST simplifies eviction in cases of mortgage default, the practical process of regaining possession still depends on the last tenant vacating the property. Therefore, the supposed advantage to lenders may be limited.

Implications for Landlords

Landlords should carefully consider the implications of the joint AST requirement. While it may align with lender policies, it can complicate tenant management and potentially expose tenants and guarantors to unfair liabilities. Landlords must balance lender demands with fair tenancy practices to maintain good tenant relations and comply with evolving legal standards.

It is advisable for landlords to seek legal advice when structuring HMO tenancies and to stay informed about changes in tenancy law that may affect the enforceability of mortgage conditions.
