foreign students are the best tenants you can get....Some/many/most tenants are financially challenged (i.e. they have no money).
I know someone who knows someone who bought a large house near York University, subdivided it into 10 rooms and rent the rooms to foreign students attending York. That house is a cash machine.
-most of them have the funds / budget for rent
-probably don't know any loopholes to stiff the landlord / probably don't have that desire too
my nephew came in as a student 2 years ago and walked him through everything he needs to have a decent living in Canada.
-work hard
-be straight with anyone
-look for side jobs that are easy to do and pays good (etc. painting, framing landscaping)
-never stiff a client because those referrals count.
-set a goal that eventually you can own at least the house you live in...
last part is the hardest with the current real estate dilemma...but still doable..
