I looked at this deal over a month ago and spoke to the seller, so I'm really familiar. Based on my conversation with her, she wanted to be done with the properties as soon as possible. Although some financing was offered she much preferred to be cashed out. In my opinion she needed a quick no nonsense deal. I didn't make her a cash offer because my valuation was in the low $300s and didn't think she would go that low yet.
Many times we try to use too much logic and reason to get the deal as you spelled out in your email. Sellers usually don't care about your reasons. I believe you would have been better off just making an offer without the long justification. It's likely she didn't even read your email. I wouldn't have read your email either and would have given you a similar response.
Also- you need to get an accepted offer before you do inspections, just write it into the offer, there is a section in the Florida farbar contract for inspection days. I'm sure she didn't want the tenants to know she was selling until the deal looked solid.
Hope that helps!
