Agree with the others. Talk to letting agents about what sort of rental market there is locally, and what there expectations are in terms of decoration/furnishing etc. Also use these conversations as a way of interviewing Agents.
Decide if you can handle the sort of tenant you are likely to attract. I once knew someone who got high rents for poor properties from some pretty desperate tenants, eg people leaving prison, but she was married to a 6'7" bouncer. Again you probably need experience to let to students. (First time away from home, and not always house-trained!) I don't know if it still exists but Registered Social Landlords (Housing Associations) used to have a scheme whereby they took on the tenancy, paid you the rent, and restored the property to its original condition at the end. Who they housed, whether they paid, and what they got up to was then their problem.
If the property, in the right condition is likely to be attractive to young professionals or working families, you should not have too much of a problem. Worth though making sure it is in nice condition. People who will look after a property, normally want a property that has been looked after. Spending money on updating a property should then increase its sale value.
Work out the cost. Then decide if it is worth borrowing the money. Mortgage interest is tax deductible, so as long as the fee structure is OK, it can make sense. There are a huge variety of BTL mortgages, so it is probably worth going through a broker, indeed most are broker only. London and Country, to name but one, don't charge for the advice.
Then talk to your accountant. If you are married it might be worth transferring the property to joint names for CGT reasons, if furnished you can get a 10% wear and tear allowance, etc.
