Some bad things about renting are first, the home will most likely never be your home. That means sooner of later and way to often you have to move. It gets expensive to move even if you do it yourself. Thousands of dollars can be spent every year just relocating.
There is security in owning your own home. It is your home until you choose to leave. On the downside your monthly rent is paying for someone else's home. You are not getting the tax benefits of home ownership.
Your children may be forced to change schools and you have no control over whether the rent stays the same or if the owner wants to sell the house. You are a transient resident without control. Buy the right house, when the time is right. Thank you for asking what are some bad things about renting.
