As is usual in the industry the TENANCY (or DILPIDATIONS) DEPOSIT required is the equivalent to six weeks rent and a tenancy cannot proceed without the deposit and the balance of the initial funds including the FIRST MONTHS RENT being provided in cleared funds prior to commencement.
All your costs associated with renting a specific property will be advised to you in spreadsheet format immediately you have decided to proceed with a property and prior to proceeding with an application to rent.
You will be required to complete a formal application form which will be made available to you online. Hard copy format will also be available should you prefer.
For the avoidance of doubt, there is no obligation on the landlord or his agent to place said deposit in an interest bearing account.
