Types of fees:Application fees:  Above info is spot on, the only advice I would give is that higher fees means less applicants (we decided not to charge at all when we self managed, it did not add up to very much each year) and if it is non-refundable there are likely tenant-landlord laws about what you have to disclose about your criteria before they apply.Late rent: If rent is late, there is an exra fee.

I own MTR's in a San Antonio medical center and I can give you this advise: Traveling nurses/professionals are looking for small accommodations (lower price point), they are concerned with safety, as they are usually women traveling alone, well-lit walkways by their parking spot, private entrances/bath/laundry.
