Your house rent is your house rent, though it can be your apartment rent too.
The reading for 家 is an exceptional one. It is や, because when your landlord asks if you paid your rent, you always say yah (や), whether you did or not.
If the rent is this much, I might be able to manage living on a small salary.
I renewed my contract for the apartment yesterday, but I didn't understand why the rent was $500 more than last year. I thought about moving out for a second.
When I think about the way Fugu treated me, I realized that he was a real jerk. I paid his rent, phone bills, groceries, and everything, but he ended up cheating on me!
