Your rent is too high and there's a great opportunity to move to perfect premises but you need to get out of your existing lease. Know the barriers and how to overcome them so you're ready to move when you need to
Options depend on your lease. You may be able to:
If you can terminate at a specified point, because there is a 'break clause' in your lease, you may have no continuing liabilities to the landlord. Check the notice you have to give, and that you have complied with conditions in the lease, such as keeping the premises in repair (breaches may lose you the right to terminate).
If you can negotiate termination, you may have no ongoing liabilities to your landlord but he will try to get you to pay a fee for terminating, payment of his professional fees and payment for repairs and redecoration.
Finding a new tenant to take over your lease - someone to 'assign' it to - is usually the best way of realising any value it has, but leases for fewer than three years often prohibit assignment, or you may need your landlord's consent which usually can't be unreasonably withheld. Or there may be restrictions on use that limit who you can assign to.
If you can assign, you'll usually have legal liabilities for all future payments owed by future tenants, or have to guarantee some or all of the next tenant's payments. The landlord will try to negotiate other payments from you that you may be able to pass onto, or share, with the new tenant.
Assignment negotiations can cost more and take longer than negotiations to terminate. First, you have to find the new tenant, and may have to pay an agent to help. Second, you have to negotiate with both the new tenant (for example: who will pay the landlord's professional fees? will the new tenant pay you a premium, or vice versa?) and the landlord.
If your lease has less than two years to run it's probably better to negotiate to terminate the lease, to avoid the costs and risks of assigning it.
Rental from subletting could cover part or all of your rent and leave you free to move but subletting won't get you out of the lease - you retain all your liabilities as a tenant and you have the additional burden of managing your sub–tenant.
Subletting may not even be allowed - check the lease for restrictions on subletting - or you may need the landlord's consent.
Whether negotiating an assignment or termination with the landlord, put yourself in the landlord's shoes:
You need judgement, experience and a good knowledge of the local market so use both your own - and your adviser's - negotiating skills. Don't give your position away. If the landlord knows you are desperate to get out of the lease, the landlord will have the upper hand.
If in doubt, take legal advice.
