I had the same thought about pets. A friend had several large dogs. When she had her house for sale she couldn't understand the lack of interest, but I'm sure it was the whiff of wet dog that you got whenever you walked into that house. Those Febreze ads are right about the concept of " nose blind".Watty wrote: ↑Sun May 26, 2019 9:15 pmDo you have any pets, especially any cats?
If so then there could be pet odors that might not be all that bad but if a potential buyer gets even a whiff of an animal, or sees that there is a cat or other animal is in the house then that can be a deal killer for many if not most people.
Has your carpet stretched out so that there a rolls or waves? When I was selling my condo (after renting it out for a few years), I got the guy who had done the carpet installation back out to tighten it back up again in a few high traffic places. (He had let me know when it was installed that he did work on the side). A professional carpet cleaner may also be able to point you in the right direction if this is an issue.
My realtor at the time also has a good suggestion which was to replace light bulbs with higher wattage bulbs so that the rooms looked bright. It made a huge difference since my tenant had been using low wattage bulbs. (This was back in the days of all incandescent bulbs). But I find LED bulbs to be much brighter than compact fluorescent bulbs or incandescents, so you might consider whether this would help in making your house more appealing.
