Believe me, i've seen houses of so called 'professionals' who don't give a shit about their places
I used to work in and Estate Agent and dealt with a number of rentals. One guy was a professional renting an initially immaculate flat in a very naice area. This particular bloke was paying £1,200pcm for the flat, which had a very expensive Italian leather 3 piece suite, an expensive bed/mattress and other expensive, solid wood furnishings.
Said bloke got drunk a bit too regularly and over a short period of time, ruined most of the furniture, and either vomited, shat or pissed over the leather suite/floor/carpets etc. He was evicted and the owner had to replace the ruined furniture which cost of around £25,000.
The next tenant was a dog owner with a carpet washer, pet insurance (with 3rd party liability), washed her dogs regularly, trained and exercised them so well that the dogs were too pooped to even lift their heads off the floor. The LL said that although he was so anxious initially, about the dogs, he now sees that not all dog owners are shitty tenants, and not all professionals are good ones. The tenant is still in the property to this day, and the LL has had no problems with her in 20 years.
The LL said he would certainly rent to pet owners as long as they had, and he could see the pet insurance documents. No insurance, no renting.
TBH, the market may open up a bit more if pet owners insured their pets appropriately.
