If you're letting (or thinking of letting), you must be aware of your rights, responsibilities and legal obligations to tenants.
The law protects tenants; in particular, there are laws and procedures that govern:
For tenancies in England see the government guide: Landlord and tenant rights and responsibilities in the private rented sector
Before you can start letting, you must first check that you have the right to let the property. You may need to get consent to let from third parties.
If you have a mortgage, you must get your mortgage lender's agreement to let the property before you do so.
Some properties have a lease as the document of title (for example, flats/apartments, maisonettes, and many residential properties built pre-2000 in Northern Ireland). For leasehold properties, you should check the terms of the lease to see whether it gives permission to letting. If necessary, you'll need to get permission from the freeholder (or management company) before you may do so.
In Northern Ireland, if you are the first purchaser of a new house then there may be conditions in your contract for sale that prohibit you from renting the property, either for a designated period of time or permanently.
You should check with your insurer whether your buildings insurance policy will provide cover if the property is let; if it doesn't, you may need to extend the cover.
