Look at this cracking two bed flat currently on the market for sale. This should easily achieve a rental value of £725pcm giving a very healthy 5.7% return.
We have sold one of these and they come with really long leases and very low maintenance charges. Combine that with the added bonus of a garage and being located in a popular part of town this is a cracking investment.
The one we sold we had rented for several years and never had trouble letting it. Definitely worth a look!
