There was so much garbage in the house I was talking about that my buddy was convinced they actually brought extra in to spite him. He refused to believe that anyone could actually live that way.
Neither of the guys I referred to will ever rent again. Some people aren't cut out for the harsh side of being a landlord. In the first case, he wasn't even trying to be a landlord, he just didn't want to sell his house and couldn't afford to pay rent in BC and a mortgage in Ontario.
As for rent being too (damn) high (someone has to post the meme), that's not a factor in either situation. In the first situation, it was over ten years ago, so everything related to housing was less insane. In the latter case, he actually listed lower than market in hopes of attracting solid, long term tenants. Not a good plan, in hindsight.
Where I will agree is the tenant law in Ontario doesn't serve anyone not well versed in the system. Professional landlords seem to navigate the system okay, and professional scam tenants know how to manipulate things to their advantage. The people who get screwed are the amateur landlords and well-meaning tenants. In BC, tenants have a lot less protection. For example, damage deposits are the norm, with unscrupulous landlords being expert at finding ways to hang onto it, regardless of actual damage.
If your sister is looking in Guelph, you have my sympathy. My son is looking for something for just the fall semester (he'll be an RA in January), and there's almost zero available, especially for short-term. What does come up is either insanely expensive or super picky (lots of female only requirements), and is typically rented almost instantly. Apparently UofG over-enrolled for first year (whoops, shame about that extra cash), overflowing res and putting extra pressure on an already slammed rental market. It's actually getting to the point where he may just skip the fall semester.
