How do I know which paperwork to use for mid-term, furnished, rent by the room?

[Clareen Eberly]

Do I always need to have a prospective tenant fill out an application to rent? Is that so I can weed out any prospective tenants there if something is a red flag? Then if all looks good though, I send them the residential lease agreement to finalize? Since we are doing mid-term, I wasn't sure how much that would differ in terms of paperwork from the traditional 1 year plus leases. Thanks in advance!
