She's already on top of that. We went over comps before putting in the bid, but for the appraisal we need to make sure we have ones that are the closest possible, and there's over a month of extra time since we last covered them. Plus we'll need to look at that size difference, since we did think the home was 240 sq ft larger than it actually is.
But ultimately it's still going to come down to whether the appraiser is willing to drop, or emphasis less, the short sale. We're not going to find many, if any, sales, closer than that one (it's 0.3 miles from the house I'm buying). But yes, we do at least want to have comps ready for the next one if we do need to go that way. I have seen that mentioned reading over other topics on here, that it can be good to be pro-active with the appraiser in terms of offering comps, correct?
And this may depend on if the seller is willing to take at least some cut in price based on the size being wrong. If they refuse to come down at all, then I'll have to walk away. So regardless of how it does turn out, the appraiser will have done me a big favor by finding that mistake in the size of the house. My impression of the seller though is that they really want to get this home sold and they aren't too stretched thin to compromise some.
