When potential tenants give you a list of things they would like fixed in your property before they move in, do not offer to fix only the cosmetic issues and ignore the safety hazards. That's a real great way to tell said tenants that you cannot be trusted to fix any real issues should they arise, and make them (if they have any sense at all) run screaming.
Our realtor, on the other hand, is made of the awesome. The snark she put in the letter telling them to fuck off was priceless.
