I'm no pro, so take this as just knowledge from my recent reading here.
I'm not sure I would pay much attention to an ARV that a wholesaler is giving you. I'm sure there are reputable ones with track records and such in that area, but if this one is new to you I'd be careful taking ARV advice from them. Obviously it's in their interest to make you think the ARV is sky high.
I would look at similar listing in the area that are available to see what the 'norm' for the area is as far as finishes. I'd also look at as many SOLD comps as I could, paying particular attention to what was done in them VS the sales price.
Personal preference, but I wouldn't feel right selling the property with any sort of serious moisture/mold issue or rot that could be a fairly easy repair.
Since you certainly would know the area better than a lot of us, I'd recommend going through your SoW and rating the items. For example, on the left of each put the cost on a 1-5 scale, 1 is cheap, 5 is expensive. On the right put your approximate impact on resale price, 1-5 scale where 1 is no impact, and 5 is huge impact. Then put the right number over the left number in a fraction and you have an impact / cost factor. The higher the better! I thought this up when doing a few practice CMAs in my area.
I haven't purchased a rehab property yet, so take this for what it's worth. Just my 2 cents. Hope it helps in at least a small way!
