I second the suggestion to take pictures on the day you move in and again on the day you move out. Make sure that they are dated. This is your defense if the landlord withholds money for damage. If the place isn’t spotless, be sure to capture this in the photos.
If/when you move out, count extra time to come back and clean. It doesn’t have to be move in ready, but if you leave crap behind, some landlords will charge you disposal fees.
Take time to read the contract. My daughter’s contract put in it that each student was responsible for up to $150 for carpet cleaning, on a ~1000 sq ft 2 bdrm place with maybe 400 sq feet of carpet. Guess how much he charged each student? Ridiculous to charge $600 for carpet cleaning, but we couldn’t fight it after the fact because it was in the contract.
Many landlords charge additionally for pets, sometimes up front, sometimes monthly and sometimes both. For instance, my daughter had to pay $250 up front for an additional deposit on damage + $25 non-refundable each month for the cat her MIL gave her.
Look at the contract before putting nails in the walls.
Get renter’s insurance. Your landlord doesn’t have the ability to insure your belongings, even if he/she wanted to. It’s usually very reasonably priced. If the place burns down, or gets flooded, or whatever, this will cover replacement value of your clothes, computers, ipods, big screen tvs, etc.
Pay your rent on time.
If parking is an issue in the area you buy, look for a place that throws in a dedicated parking space.
Where to look for apartments varies on where you are and what you’re looking for. It used to be that the Classifieds was the place to look, but the internet has changed all that. Call an agent in the area you’re targeting and ask what going rates are. They should know the market.
If you’re looking for affordable apartments, stay away from areas immediately surrounding colleges, as rates are usually sky high around universities, because parents are subsidizing their kids.
That being said, if you need roommates to help pay the rent, then staying closer to a university or big employer will help you find roommates, as most have a bulletin board for folks looking for roommates.
