The main disadvantage of the commonhold model of ownership in the senior living sector is that, short of an independent operator being brought in to provide care services under a contract with the commonhold owners (the terms of which would need to be specifically negotiated), there is no landlord in place to provide care services or delegate the provision of care services to the commonhold occupants under a single contract negotiated with a care provider. This is a problem which is unique to the sector. It is not experienced, for example, in PRS schemes, where health and care services are not required by the vast majority of occupants. The landlord's role in negotiating, entering into and policing care contracts at the freehold level is removed and the burden must be placed on the commonhold association, who may not have the commercial experience or negotiating power to secure beneficial terms for the commonhold occupants. By contrast, the leasehold model offers a convenient division of responsibilities between landlord and tenant for these and other professional or commercial purposes.
In this and other respects, commonhold will have to compete with the leasehold model for some time. This is not in the least because of the prevalence and length of leases which are already in circulation (particularly long leases with terms of 99 years, 125 years, 150 years, 999 years etc), which would need to be extinguished to be replaced, but also due to lack of familiarity. This lack of familiarity brings with it problems with obtaining finance or accurate valuations on commonhold property and it can be more complicated to insure. Fewer mortgage products are currently available on purchase and the pool of potential purchasers for commonhold properties may be limited due to a lack of understanding of what commonhold ownership actually entails. Some purchasers may in fact be put off by shared management responsibilities which they would otherwise prefer to have been administered by the landlord, particularly in the context where the commonhold association has not appointed a professional manager for this purpose. This is particularly the case in a retirement living context where occupiers are typically looking to take on less responsibility rather than more when they move into the scheme.
It is also unclear how commonhold ownership will operate in a mixed-use context. This is a challenge for senior living schemes which offer shared facilities with a commercial element, such as restaurants, leisure facilities, or guest accommodation available at an additional charge. Many of these elements involve outsourcing to third party operators; are run at a profit which needs to be paid back into the scheme and re-administered; or require independent licensing (such as for the sale of alcohol or provision of entertainment) that must be carefully regulated. This will nearly always require the involvement of a professional manager whose expertise will come at a charge. Management arrangements such as this, even though negotiated on commercial terms, would not benefit from the many protections which have been set down in statute and at common law in respect of leasehold service charges regimes and have evolved over several decades. It is questionable, therefore, if residents are left more exposed when entering into independent management arrangements where they are free to enter into a "bad bargain" (the avoidance of which would require sophisticated commercial negotiation and advice) and would in any event have to pay a fee for. It diminishes the argument that commonhold ownership provides better opportunity to reduce costs and also the argument that it offers better protection for its participants, given it has not been challenged in the courts and has no body of case law supporting it. This would change over time, but it would be a lengthy process.
Removing the leasehold model also creates new complications. Aspects of real estate management that are regulated under leases and are in the common interest of all occupiers (e.g. restrictions on alterations, changes in use etc) have to be regulated by the commonhold community statement rather than under the individual leases granted for the estate. All residents are required to sign up to this statement on purchase, and have their buyers sign up to the statement on sale. However, rather than one party (the landlord) being responsible for enforcement, as in the case of leasehold ownership, all residents would be jointly responsible for enforcing it between themselves through the commonhold association. How exactly this would work in the case of one or multiple defaulting parties (who are themselves party to the document), and in circumstances where not all parties are inclined or willing to enforce, is unclear and could create huge complications. Failure to take prompt action or granting individual concessions could result in accidental waiver of certain of the provisions in the document, which would then become more complex to enforce over time. There is also the question of how enforcement will work if forfeiture is not available as an ultimate sanction – the forced sale of individual units would be an inequitable option, but means uncooperative residents remain embedded within the scheme. Delegation of enforcement or management responsibilities by the commonhold association to a managing third party could circumvent some of these issues, but this does not do away with the complication that that managing agent has been appointed by and acts for the residents jointly, some of whom it would then be responsible for enforcing against.
Ultimately, collective ownership brings with it the complication of enforcement against individuals within the collective, and that is never neat. Common ownership also comes with the assumption that all parties have the same interests in common, which is very unlikely to be the case for the entire duration of the time that the various owners and their successors remain in residence. Though commonhold decisions are made by vote – a process which is innately more democratic than that allowed under any lease – it is impossible to satisfy all parties who, as joint and common owners, would naturally all expect an equal say. Quite aside from issues with enforcement (which is the final stage of problem-solving), if there is any disagreement in the collective or delay (over, for example, any items of expenditure or effecting structural repairs upon which individual units are interdependent), this could lead to larger problems which are ultimately more costly and time-intensive to resolve. The withholding of payments by certain residents may also put the solvency of the commonhold association at risk, with as yet no mechanism to prevent this from happening.
