Hi John,
Train lines can be a drawback for some, but there are ways to ameliorate that issue. e.g. double glazing of windows facing the train line can help – a bit more expense of course. Also, high fences can help to deaden the noise. If these exist (and are wooden, concrete, or composite – not metal) then that could reduce the decibels and some buyer reluctance along with it.
Then again, trains can be useful for some – if commuting daily on a train, the proximity to a train line could be considered a benefit. I’d be checking values of other neighbouring properties to see if the train line affects their vals markedly. Check too how often a train goes by – some lines are actually not in use. Are these short trains (i.e. do they go by in a few seconds, or are they goods trains clacking away for 2 or 3 minutes or more?)
Some might offer a place with a nice loud stereo system or HD TV with a quality sound bar that they can have playing when showing the place – all about disguising the sound of any passing trains.
There are a few ideas – what more can be done? Help me out folks !!
