John and Bryant, thank you for replying and your interest.
John, we only saw the house once in August. We are in Ontario and the house is in New Brunswick. We do have some concerns about a few issues we saw but won't be able to look more closely until we get an inspection. The roof was replaced a few years ago and poor water control is something we've discussed as a possibility. Thank you for reminding me though. It's on the list now. A pond might not be necessary after all, although it's quite likely I'll look to see if one is feasible.
Bryant: We are in Ontario and the house is in New Brunswick. The listing photos don't show the lie of the land and at the moment we don't have any of our own. The county's topographic page isn't detailed enough to be of any help either. I'm working from memory and the location of the pond I'm thinking of would be more then 200 yds from the house and require a drainage out to the front ditch as the land begins to rise back up on the opposite side. That is if memory serves me. lol! If we can firm up the deal and move in before the snow flies I'll be able to post photos then.
