Worth it equity improvement opportunities

[Duane Ward]

To my limited research knowledge, it seems that basements can't be considered in the consideration for square foot livable space equity in appraisal in NY. However, in listening to BP 598, David was talking about various ways to rehab for the BRRRR method. Would finishing a basement be enough of an equity opportunity to consider a property a good BRRRR. If not, what would you consider the smallest improvement that would be a great opportunity? Updating?
