If you're a landlord, you'll probably agree that it's better to let your property to tenants who plan to stay there a while, rather than to short-term occupants who intend to move out after a few months.

The process of finding and vetting new tenants can be arduous, and there's always the worry that the next renter to sign a lease won't be as tidy or reliable as they look.

If you've got good tenants who pay their rent on time every month and take good care of your property, then chances are you want to keep hold of them for as long as you can.

In today's economic environment, where buying a home is looking increasingly unlikely for many couples and young families, that's becoming a little easier, according to the Tenancy Deposit Scheme.

Spokesman Malcolm Harrison explained that five years ago, the average length of a tenancy on a rental property was around 14 or 15 months.

"Fairly quickly after that they were increasing up to two years and I would not be at all surprised if they have increased quite a lot since then," he remarked, pointing out that people are often reluctant to move home when the economic outlook is uncertain and they are concerned about their job security.

"I haven't got any figures to substantiate that the initial tenancies are longer, but the probability is that people are looking to stay for longer than they would have done before," Mr Harrison stated.

Of course if your tenants remain in your property for several years, you may find you have fewer opportunities to negotiate rent increases.

However, on the up side, you'll be able to build a better relationship with your tenants, and when it comes to landlord insurance, you could find yourself making fewer claims to cover things like rental arrears and dilapidation to the property.
