With a Guide Price of £225,000 – £230,000 this 1 bed seems to be priced extremely fair taking in to consideration some 1 beds in the Sidcup area have been selling up to the £250k mark. The selling agents 'Capital Sidcup' advertise the property as very well presented and from the pictures it looks in very good condition ready to rent out straight away. The flat is located within very easy reach of local amenities including local shops and New Eltham station is about 0.7 of a mile away.

We recently let a similar property near by for £850 pcm so I would expect this property to achieve around the same.
As with any leasehold property please check the lease details relating to the current maintenance/ground rent charges and that the lease will allow you to let the property out.
