New 200 amp circuit panel, Culligan water softner, new washer/dryer, and a deep clean Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

This has a cost but nothing close to what you’d have to pay investors in a pool, which is something else you mentioned.
