Oh, after our first tenants destroyed the house to the tune of £20k, ran off with all the furniture (it was a fully furnished let), we still made it look nice. Spirit markers on all the walls, 3 coats of paint was required, nail varnish poured on all the carpets, the kitchen floor tiles needed ripping up and changing they were so badly damaged. It took months of refurbishments and no income to pay the mortgage with. We were naturally landed with the tenants utility bills that she had not paid either.
The next set of tenants moved into a freshly redecorated house in perfect nick, all with new furniture. It breaks my heart to see the state of the house now.
It is going to cost us a further fortune to put it right again, before moving in again after 3 years overseas (and 1 year living around the corner as they had a 2 year lease and we returned earlier than we thought).
We could not sell the house, the downturn in the property market meant we were stuck in negative equity, so rather than freeing up money and have something for a new deposit, we would owe the bank money, if we sold.
Renting is cushy compared to letting. Having rented now for a year, I know what I prefer. Changing a light bulb you need to do whether you own or rent, but if you own, you need to pay for repairs to your own items that your tenants have caused simply through lack of care.
I am not surprised to learn that most landlords these days rent totally unfurnished. I would, if I had to let property again.
I had to offer furniture to even get tenants through the door.
I think you should put that large chip on your shoulder in the bank, it could be worth a lot if you cared well for it. It might even get your deposit for your own place sorted.
