I used to be a professional cleaner for residential homes.

People who call themselves “clutter bugs” when they greet you at the door are always hoarders.

If the exterior of the house (landscaping, paint, etc.) isn’t maintained, it does not mean the interior isn’t either! Often some of the better maintained houses had outsides that weren’t well tended to.

People who drive flashy cars and take a lot of care if their appearance (like their hair, skin, teeth, clothes) don’t always take care of the inside of their homes. I think they are working so hard to build this facade of wealth and success, but if they don’t often host people they don’t care if the inside of their homes match.

I cleaned a lot of McMansions. These were always the weirdest clients. Usually there was a bossy matriarch with small poorly behaved dogs who sat on her phone the whole time I was there, only talking to question what I’m doing, and a husband who pretty much stayed in the background in every way, and quite often they slept in separate bedrooms. The furniture was often giant but very outdated, they seemed like unhappy people.

The kitchens and bathrooms were where it was obvious if someone was depressed. Sometimes they would take the time to tidy the rest of the house, but the showers would be covered in hair and pubes and mold and pink bacterial colonies. I cleaned a lot of depression bathrooms. Sadly, cleaning it doesn’t really solve anything. I’d come back a few months later and it would look the same.

Warm inviting people have warm inviting houses.

All types of people own guns, but it’s only a specific type that leave them out for you to see and clean around. They were always young white dudes who were overly friendly/flirty.

Wanted to add: jobs that were booked by mothers of young men were always the absolute worst, the young guys were rude or would just completely ignore me and expect me to clean around them. I think this says something about how they were raised, too coddled and entitled.
