There's a huge attitute problem amongst the young couples in Israel.
I have 29 apartments in all different sizes. I would say its 50/50 good couples bad couples, not a small minority.
I help manage the luxury assets in the Jerusalem Chareidi submarket... Most apartments are in the new development's that have sprung up in the past few years in the northern neighborhoods.
50% of luxury apartment clients not being good tenants is kinda a bit different than "a huge attitute problem amongst the young couples in Israel". The vast majority of young couples don't rent luxury apartments, so it's 50% of a small percentage.
You remind me of Airbnb hosts complaining about high wear and tear, garbage, loud parties and the like. Do they think that the 100%++ premium that they're charging for short-term comes for free? Of course they have to deal with problems if they rent short term, and that's what they get the big bucks for.
Your business is similar: you rent out apartments to at prices that Israelis wouldn't pay, and then when you have to deal with your tenants "breaking terms, giving proper notice, subletting, ignoring Arnona, demanding furniture and fixtures, cleaning, leaving junk, etc "being bratty and feeling entitled"" you come out here like a victim. Did you think that you were getting that premium in rent for free?
If this is the way to get your clients the highest ROI after accounting for all the garbage that you have to deal with, then just look at all their "bratty-ness" as the cost of getting those high rents. And if you're really losing tons of money on their shtick, then maybe your investors' ROI would look better by buying simpler assets that could be rented to the general, responsible more long-term population.
