I admire your desire to be a good person but perhaps you haven't seen much of the real world.

Friend of mine in financial troubles father passed away and he proceeded to put dad's house on the market for rental. An Egyptian guy with a family wanted to move in. He resisted the urges of friends to "not rent to those people". Just before signing all the papers, a friend of his who works in immo found out that the guy owes loads of money to his previous landlord and was basically a nightmare tenant.

I myself bought an apartment from a Moroccan guy who owned the whole building (5 apts). After I get the keys and I find out he was a "huisjesmelker", renting out 10 "apartments" in that building individual rooms without sanitation and all that. The entire building was pretty much f*cked from not having done maintenance and doing very shitty "renovations". The city actually knew about the irregularities but did nothing about it.

All that's sorted now and one of the apartments is sold to a Moroccan family who (long story short) now owes 2500EUR to his neighbors because he just refuses to pay his part of the repairs that had to be done. Denies that he ever agreed to it, claims he doesn’t know what’s going on, refuses to stick to the payment plans that he previously agreed to. Turns out there’s 2 whole families living in 60 sq meters, the veiled women refuse to make eye contact with anyone in the halls, the guy is extremely rude to the women who live there. Unemployed, “can’t read French sorry and I don’t have any money”. It’s a nightmare.

If you give me the choice between living somewhere where do or don’t have these problems then without wanting to generalise, I’ll make my choice based on my own personal experience and I welcome any means that helps me made this decision.

Problems can obviously be created by anyone but in Brussels the situation is obvious and very easy to illustrate.
