So turns out after inspection, we found that the big blue house is wracked with termites. Very sad about this, but also glad because at least it was so bad, that it was easy to see, and not a future problem for us after purchase. Heading back out to look at more houses this afternoon. We have found one we like, but it's a little different than we first imagined, so we'll see. On a plus note the buyer for this house has signed on the dotted line, deposits made, so all is going swimmingly this end. I know it will work out in the end - Que sera, sera!
