Scope to the Exit
The correct scope for a property depends entirely on what you plan to do with it. A flip, a refinance, and a long-term rental hold call for different decisions about the same house.
For a resale, the scope should target what the comparable sales in that specific submarket actually support. For a rental hold, durability and maintenance cost matter more than the finish level that photographs best.
Over-improving is the most common and most expensive mistake. Money spent above what the comps support does not come back at sale.
