Stevenson offered many good points to consider. I would add make sure you can get clear title to the house (no liens, etc., against the property) and check what might be listed by way of easements against the property. Have a chat with the local land authority (I don't know what it is called in your area; here it is a municipality) to see what they have by way of zoning for the area, proposed and/or approved future development, permissions required for doing renovations, etc. Also if there is any "junk" (old vehicles, lumber piles, etc.) lying about, which I don't think there is as the property looks pretty clean, make it a condition of sale that is removed by the seller by a specific date before you move in. It probably wouldn't hurt to check out the neighbours as well -- quietly of course (you don't need to do criminal checks or peer into their living room windows).
It's not a bad looking place over all. I wish you well with it if you get it.
