You get a short visit and no second chance to form a first impression. Spend it on the things a listing cannot show you, not on the things an inspector will find anyway.
This is where your time is best spent, because it is the information that only exists in the room:
Open a few things. Closets, the electrical panel, the furnace room, a window that faces the neighbour. Sellers do not mind, and the rooms nobody staged are the honest ones.
You are not there to assess the furnace, the roof or the foundation, and a confident guess at a showing is worth nothing. Note what you notice, then let a licensed inspector price it properly during your condition period. What you are deciding at a showing is whether this home is worth an offer at all.
By the fourth home they blend. Photograph anything that puzzled you, write one sentence on what you liked and one on what you would have to live with, and send both to your REALTOR®. That second sentence is what sharpens the next search.
