A rental property or income property should look good, period! Needlessly to say, the work should be as professional as you would have done in your own home. However, may landlords tend to overdo it and end up spending in cosmetic items that seldom result in more offers and higher rent.
Better lighting, added or upgraded appliances, storage space, windows that work, bright paint, or an intercom/entry door system should bring in more rent than a property with new hardwood floors and granite counters that lacks a dishwasher, and – in case of apartments – where the tenant’s guests need to call them from the front porch to announce their arrival.
