Can a landlord force you to allow his agent to show home?

[Lee Woods]

A very long story short, our landlord was debating putting her house on the market. We offered her 250 more a month in rent to keep it off the market for a year because we did not want to live in a for sale home (otherwise we would relocate) and she agreed and said she would send the lease that week. We left to go on a trip (which she knew about) and when it was too late for us to find a new place and just a few days before the lease was up, she said she changed her mind (we did not pay the 250 extra but the house is for sale currently). We have a 60 day out clause in our lease, and we gave her notice today. She has been a source of a lot of annoyance, inconvenience and genuine rudeness and we just truly do not want to allow showings in the house while we are living there. There is no benefit to us and only a huge inconveience. I'm ok with allowing some but she is trying to enforce us to show every request. She lives in California and we live in Florida. We have an addendum in our lease that says either my husband or I need to be home for showings. We also have an addendum that says we have to show with 24 hour notice and work with the agent to accommodate that. My question is, given the terms in the addendum, which takes precedence? If I do not agree to show the house, is that a legal issue? We're already leaving so she can't evict us. Since it is her agent and not her who would enter the house is he allowed to (we have ADT and he doesn't have the code)? Everyone is telling me I don't need to agree to showings but I just want to make sure I can say no when I want to, per the addendum. Will this cause an issue with our security deposit? I am not trying to hurt her chances of selling the house, I just don't feel as though I need to go out of my way to accommodate her (for many reasons beyond the ones listed here).
