Anyone else have any advice for cleaning the house?

I could put this under OCD since part of the problem is my hoarding. Also, I have never actually fit any dx... Regardless...

I used to be okay at keeping things clean since I had other people around. Now the only person I have to keep clean for is myself... I invite people over sometimes as motivation but then I still don't bother and end up just telling them not to come.

If I owned the house I think I wouldn't even care enough to post this... but I do not own it and therefore often feel guilty as I am sure I have caused some damage in places as the house is old and mostly wood. So as soon as I even start thinking about it I feel guilty and gross and avoid it... It also occurs to me how unhygienic it can be.

The hoarding is a bit of a separate but related issue. And I am always paranoid that someone is going to show up and see into a window...
