In order to get an apartment ready for a brand new renter, there are costs associated with prepping the apartment home so it's ready to go for the next resident. This typically includes cleaning, carpet steaming, painting, and other repairs. Apartments fold this cost into their monthly rent rate and need to account for this in short term leases as well. If you plan to rent your apartment for less than 12-months, the cost to prepare your apartment for the next resident, and market the apartment once again needs to be incorporated. Depending on the lease length you choose, the community, and availability, short term premiums will differ so shop around. Be sure to ask the leasing agent about short term premiums if you are looking for a shorter apartment stay.
