We don't live in private let now, but for about 2.5 years we did (in the noughties,) and I fucking HATED tenancy inspections. The first couple were bearable, (they were every 5-6 months,) but the more they went on the more I hated them/dreaded them. The last one we had was a new/different company than the previous 4 or 5, and the man doing it said he has to look around every room (big ex council house, 4 bed, utility, bathroom, back hall, front hall, downstairs loo, lounge, kitchen, dining room, conservatory loads of rooms.)
He said 'I have to take photos for the landlord,' and proceeded to take around TEN photos in each room. I was gobsmacked and blindsided, and didn't stop him. (I regretted it hugely later and was angry with myself for not stopping it.) (DH was at work.)
I mean, he took a LEAST 140 photos, and I know it sounds dramatic, but I felt a bit violated. There were our private meds lying about, family photos, personal belongings, jewelry, clothes, various collectibles (some quite valuable,) and even bits of underwear on the radiators and a clothes rack in the bedroom, etc. Just nosed around every single INCH of the house, and took photo after photo... I felt so annoyed, and was determined I would never let this happen again. I do NOT know why he took all these photos, but the more I thought about it, the angrier I got. Especially with myself, for not stopping him.
But we left before the next inspection anyway, so it didn't happen again.
I know I should have complained to the property management company, but at the time, I was afraid of losing the house. Luckily, we were able to leave some 5 months later.... For somewhere permanent. Sooner than we thought!
