Your question makes me think you are not a licensed broker. If you and your friend are trying to buy the place without the hassle of a real estate agent try using our online do-it-yourself site. There is a "buy it" form located on the listing page for this property. If you want to make an offer fill it out and our company will submit it for you and make sure your interests are legally protected.
To answer your question on price an offer of 325K is a 16% discount off asking. The average discount from original price on norwood single families (in the last year) is 7% and the average discount from listing price is 4%. As you can see by these numbers your offer would be very low compared to the average. I took a look at properties that have sold in the asking price range and the property does not seem drastically over priced. That said, buyers dictate market values and if all you can pay or want to pay is $325,000 there is no reason you shouldn't give it a try. If you remain patient and the property doesn't sell the owner may reconsider. On 7/1/2008 59 Countryside sold for $400K - The house is almost identical in size and style so the owner of 55 Countryside is probably using this sale as a comp.
Hope all this helps!
