A little risky, not very risky. I already gave my 2 cents about consumables. Assume that if they have not been recently replaced, you will have to replace them soon. As for the rest. Inspect the bike. Any scratches or dents? Minor scratches are OK. Deep gouges, or a big dent might suggest a bad crash or similar abuse. Spin the wheels. Are they true or is there a noticeable wobble? Turn the handlebars? Smooth, or does it feel rough? Ride the bike and shift through the gears. Do they shift smoothly or is there a problem. How about the cranks? Any play in the cranks? If so, you might need a new bottom bracket.
If it all checks out, Then you are good to make an offer, assuming the bike fits.
