The rental market in London continues to be among the most competitive in the UK. As such, many locations throughout London experience an imbalance in supply and demand where there exists greater demand than available supply of rental housing. Despite this competition, however, many vacant rental properties exist for extended periods.
A common assumption regarding why rental properties remain vacant for so long is based on the view that current market conditions cause these vacancies. Although general market trends may have an impact on vacancy rates, it is typically a number of factors that result in rental properties remaining vacant for extended periods. Specifically, vacancy rates are generally due to a combination of how a rental property is priced, presented, communicated about and managed.
The difference in performance between properties which are rented quickly and those that take much longer to rent is increasing as the rental industry becomes more professionalised.
Pricing remains one of the biggest factors
One of the most common reasons properties sit empty is unrealistic pricing.
Landlords often want to maximise their rental income because of increasing costs. However, setting the price of a rental property above market value can deter potential tenant activity in both low-demand and high-demand markets.
Today’s renters have much greater access to information about the current state of the local rental market than previous generations. When renters compare available rentals from multiple websites and online listings, they can easily determine if the initial asking price for your property is higher than average or not. Even a slight (1-2%) variance in rental pricing can result in lower numbers of inquiries for your vacant property.
Also, if you initially set the asking price of your rental property too high, it may take longer to find a new tenant. This could also potentially cause issues with prospective buyers who see that your property has been “on the market” for a long time. In several situations, adjusting the asking price of your rental property downward earlier would have resulted in less vacancy time.
Presentation matters more than many landlords realise
Quality of photography, presentation and listing can be a major factor in drawing potential tenants to your property.
With the rental market becoming more visual, especially in London, with many landlords advertising their rentals online at once, it’s essential that you have good-quality photos of each room, including lighting in every room. If there are poor-quality images, the rooms appear dark, or even worse, the listing appears to be incomplete, you could deter possible interest from the beginning.
In addition to the location being perfect, this can help create an attractive marketing package online.
This is particularly important as tenant expectations continue to rise. Many renters now expect:
- clean, modern presentation
- professional photography
- clear property information
- responsive communication
- a smoother overall experience
Properties that fail to meet these expectations can quickly fall behind competing listings.
Delays in communication can lose tenants quickly
Another significant problem with renting in London is poor communication.
As a result, the fast-paced nature of the London Rental Market means that many tenants contact multiple property agents for various rentals at the same time and have to decide very quickly.
Therefore, if responses from your agent are slow, then it may be hard to get viewings arranged, or follow-up may be sporadic, and you could lose potential tenant interest very quickly. This is why communication has become so key when managing a property.
A property can generate strong initial interest but still remain empty if:
- enquiries are not answered quickly
- viewing requests are delayed
- follow-up communication is poor
- applications are handled slowly
In practice, operational efficiency is often just as important as the property itself.
Maintenance standards increasingly affect demand
Tenant expectations around property condition are also changing.
The amount of attention (influencing tenant decision making) being given to things that were previously ignored is greatly increasing. The visible presence of needed repairs or older interior design elements, or signs of neglect and lack of proper care for a home, can have a significant negative impact on tenant interest.
This issue is most prominent within the London area due to high rental rates and expectations from tenants who pay these higher amounts.
In addition to decreased tenant interest, tenants who view a landlord as ineffective in communicating with them may develop additional concerns related to overall tenancy management. Tenants increasingly equate:
- poor maintenance
- slow communication
- disorganisation
- unclear processes
to broader management issues.
As a result, even smaller maintenance concerns can affect demand more than landlords expect.
The market is becoming more competitive
While demand for rented properties has been consistently high throughout the years, the nature of the marketplace itself is evolving. As institutional landlords and Build to Rent (BTR) schemes become more prevalent, there have been increasing levels of service provision across the industry as a whole, including:
- the tenant’s experience
- communication with tenants
- whether amenities are provided
- how quickly issues are resolved
- levels of professionalism
These changes have created an expectation among tenants that will eventually spread throughout the entire market. In addition, private landlords are now competing not only based upon where their property is located and its pricing, but also based upon all aspects of the rental experience they provide.
Poor management can extend void periods
Many voids are not due to the property itself but due to how the tenancy process is managed.
For example:
- the listing process has been delayed
- there has been inconsistent contact with the tenant(s)
- viewing appointments have been poorly coordinated
- reference checks for potential tenants have taken too long
- unresolved maintenance issues have prevented the property from being ready for viewing
These factors may all contribute to the length of time it takes to rent out a property.
In particular, this will be relevant in an active, fast-moving rental market such as in London. Properties that are marketed efficiently, presented well and managed efficiently are far more likely to secure tenants promptly.
Tenant expectations are shifting
The rental market is also changing demographically.
As many tenants (and specifically younger renters) have come to expect a much more professional experience from their landlord overall, and in doing so, they expect rapid digital communication and streamlined processes similar to those found in other areas of their lives.
This does not mean that each and every property requires luxurious finishes. It simply means that:
- responsiveness
- organisation
- transparency
- professionalism
are being viewed with greater importance by both landlords and tenants. Those landlords who rely heavily upon outdated methods or reactively respond to issues will be less competitive than those who use more modern methods.
