Whether you own a pet or think you might want to adopt one, you should absolutely ask about a building's pet policy while touring an apartment. Make sure pets are even allowed before getting into the nitty-gritty details like pet fees, extra cleaning charges, etc. Pet Policies vary widely, but most properties charge a non-refundable pet deposit or monthly pet rent.
Never try to hide a pet in an apartment where you know it's not allowed. Getting caught can get costly, and lead to you having to get rid of your animal. Check to see if there are restrictions on breeds or types of pets allowed as well.
Each property handles moves differently, so make sure to ask what moving in will look like for you while visiting apartments.
For instance, are there any moving or elevator fees? Do you have to get a special permit to have a moving van parked on the street? What area of the parking lot can you take over on the move-in day and does the management company block it off?
If you're moving in on a popular day you may have to compete for space and wait to use the elevator. If that's the case, see if you can delay your move by a day or come a day early to have an advantage.
It is also essential to know if the apartment you're looking at really fits into your budget. Ask how much the unit will cost per month and what the manager's late rent policy is. Be sure to find out if there's a grace period if you get delayed making a payment.
Also, ask about fees and how much money you're expected to bring with you when you sign the lease. This should include a security deposit and possibly first and last month's rent, but other costs could factor in.
If upfront fees are too costly, ask if there are any you can roll into your monthly rent and pay over time.
Ideally, you should already know when the lease begins and ends before you even start asking questions while on an apartment tour. If for some reason you aren't, make sure you get clarification on when move-in is and how many months the lease is for.
Inquire if there are any other common lease terms you should know like quiet hours or restrictions on painting or putting holes in the walls.
