Well, I will not call myself a clean freak, but I do like my house and work space clean, my house is not sparking from the cleanness but at least is passable. But even though I am not a control freak I really do not understand how can some one live around a dirty house, messy as far as like having your clothes around the floor, or your mail a mess on a table is something I can live with, but plain dirty, dusty the kitchen full of sink for a week with all type of bugs around and the counters sticky from food, or the bathroom black with mold, kind of dirty is just plain YUK.
Many years ago I owned a Condo that due to unforeseen issues I could not sale so we rent it, the Realtor did the "Checking" and everything else and the couple that moved in there stayed for 3 years, their last year was plain awful, they paid late many months, so we decided it was time to sell, when we went in to inspect the house prior to putting the For Sale sign up, the house was absolutely dirty and messy. I mean sticky carpet and all. We got lucky and a lady decided it to buy the apartment 'As Is', we gave notice to the tenants and they of course moved the last day after midnight. It was the worse experience I have ever had.
But the apartment, OMG it was a pigsty, carpet was sticky, looks like they had had the electricity cut off and live at candle light, there was WAX candle everywhere on the carpet, the floor the counters, the stove. The bathtub on the main bathroom was black, from dirt, even after 2 full gallons of CLOROX and an overnight soak it would not go away. It took my husband 5 hours to vacuum the carpet before we could steam cleaned and that took about 3 more hours. I have never seen anything so awful. It was a nightmare.
