When I am working as a buyer's agent and showing a house, some of the details that I suggest to my clients are: examine the HVAC filters, try all windows for ease in opening and closing, taste the water and check the water pressure.
If the HVAC filters are not clean, chances are good these sellers are not very maintenance oriented. If the water tastes terrible (even if a water test gives it a passing result) the buyer may want to have a water filtration system installed. Good to know before you go into negotiations. Many people just WILL NOT BUY a house with poor water pressure.
I was reminded of this when I started doing the dishes in our new rental. We just sold our farm and are building a small home on less acreage. The water pressure in the kitchen was terrible until....we cleaned the aerator. This five minute job can make the difference between a sale or no sale.
Just another reminder: the details matter when selling (or renting) your home.
