New to bikes need advice

[Fazerider]

Not at all. Provided there's evidence that the bike's been cared for (has had regular oil changes, valves clearances checked at some point and isn't making clattering noises) there is no need to regard that sort of mileage as a problem. Fazer engines should be good for at least twice that distance.
Most people do avoid higher mileage machines so you ought to be able to negotiate the seller down to a good price.
