Things I asked to be included in lease. Reasonable?

Ladies,

We are in the process of signing a lease on a villa. The owner is a local and is using an agent. I have a few questions.

First, I asked for the agent's RERA card and she provided a color copy (checked on RERA and is listed on there) but her broker RERA card actually expired in April. She claims it is "getting renewed." In addition, she is not just any agent but appears to be the exclusive agent for this small compound and has "managed" it for years. She is super professional and very knowledgeable. Is there nothing to worry about on her expiry?

Also...

1) Should I insist the owner be present for the lease signing? I read this is important. Or that the agent has a POA. Any info or opinions?
2) I asked for the owner's legal address to be added to the lease. Currently, there is only a name and phone number on his details written. Note...I do have his current passport copy, emirates ID copy, land lease / title copy) ...per my request. What if he doesn't want to attend the signing?
3) I asked that it be added on the lease that we be notified within 10 days if his phone number changes
4) I asked that it be added that "written notice" be defined on the lease as being via certified mail (not text or email) for any changes to terms, conditions or increases. (Have heard of text/email being counted before and this could "get lost" or "never arrive"...(in my opinion)
5) The landlord is listed as covering "major things" (listing major A/C repair specifically) but also said "anything up to 500dhs in the villa was our responsibility." I assumed this meant any service or repair on the A/C up to 500dhs was on us. I countered in my reply to the agent saying we did not want to be responsible for ANY cost on the A/C (even under 500dhs). My thoughts (from reading complaints by others online) is that it would not be unheard of to have 10x300dhs trips a year for a faulty air con. said, at least in year one we would want this until we know what we are dealing with.
6) I also asked that the owner pay to service the air con at least every 6-8 months at his cost to keep them in good shape
7) I said we wanted our refund of deposit within 2 weeks. The current lease did not have a timeline on it.

Do all of these things sound reasonable? Anything we missed or should be worried about?

Thanks! xx
