In a nutshell, if you make sure the house/flat is in good nick before you rent, vet the tenents properly and trust your gut feeling about them,it is generally a stroll in the park. I opted to manage it myself, as i didnt think the agents did enought to warrant the 10-15% they were charging of the rental. I am currently on my 4th set of tenents asthey tend to upgrade from a 2 bed quite quick. When i first started out, i joined the Residential Landlords Association, for about £90 they have templates for every kind of official communication you need to stay within the law, like tenancy agreements,everything you need is downloadable and they walk you through the process. If its a second home, I would suggest you go for an interest only mortgage to maximise the profit.
