Just do the cost to cure and go on. Give them an "as is" number.
Yeah, show me the sales that support such an impact. We all "believe" that is the case but no one has ever seen it. So it becomes a unicorn mythical adjustment to punish cost to cure worse. Find me the paired sales demonstrating that you can tie down an additional deduction for some minor item. Show me some paired sales (s like in more than one) where a couple thousand for a couple of mini-splits can be extracted from dissimilar houses. Gee you can buy mini's for under 1k.
So once again I ask the question I ask so many times. WHO IS THE LENDER? Is it secondary market like FHA? Fannie Mae? or is it simply an in-house bank? Almost all appraisals for non-secondary market require an "as is" value even if you do the "subject to" value. So you should check with the lender and see. 100% of bank work I do is small community banks. And they invariably want "AS IS"- in fact, the IAG (Interagency Guidelines) require it. When they tell you "conventional" they need to explicitly tell you what kind of report they want - one for FHA? Fannie mae? or "in house".... and none of my in-house lenders require UAD or Fannie forms, and I never used them when I did form reports. And all my bank reports now are narrative.... in house banks don't care for the most part.
