An owner occupant does not expect a profit, but they do want a greater discount than straight cost for the hassle and discomfort of being in the house ( or paying to be in hotel ) while the work is being done. Contractors and workmen trooping in and out, noise, mess, delays, cost over runs etc. This is the reason some buyers will not buy a house needing work.
In addition, consider this, when a buyer purchases a move in ready house, they might pay more, but it is borrowed money. Whereas if they buy a house needing repairs or unfinished room, that is cash out of pocket to pay for it, which some do not have or do not want to part with. Therefore, with many houses needing repair it is common for the seller to provide a concession for it .
However, as others have noted, in this crazy market all norms are out the window. I have seen some dated houses selling today for the same price an upgraded house sold for 6 months ago. So clearly many buyers today don't expect a discount because inventory is so tight. Listing a cost to cure estimate for lender use on addendum does not mean we have to adjust for it - in this market, simply explain why a C2C estimate is provided but market is not seeing a discount for it. In a slow market by contrast, buyers would expect a huge discount.
Reading the market is called being an appraiser- as opposed to putting in rote formula adjustments ,
