If your friend knows this area, let her advise you. That is far better than trying to "read" a market which is not a proper market. There is no transparency, and there is so little volume that the last comparable sale in an area may have been 6 months ago, or of a very different house (e.g. extension/no extension, refurbished kitchen/no refurbished condition, new flooring/70s flooring, length of garden in a wedge-shaped street...) A recently high-priced sale may have been the result of a distressed buyer (people having a baby, or people desperate to get into school catchment area before application deadline), or a low-priced sale could have been the result of a distressed seller (e.g. divorcing couple, elderly person going into a home and needing to pay fees).
With no transparency, prices are seemingly set at whim, and there can't be any "insult" at an offer, because it's far from evident what asking prices should be.
By contrast, it should be very clear to you and all other potential buyers what price you can and will pay, because you will be the ones paying it back. If you are about to go off work on maternity leave, price that in. If you are worried about Greece, price that in. If you see that properties in this area are not moving, and that asking prices are near 2007 levels, people are reluctant to buy at these levels, and you should price that in, too.
Houses are only worth what people will pay for them, not what vendors "need" to sell them at. Of course, the reverse of that is that if the owners are not distressed sellers, they can hold out as long as they like, or can stand it.
