I'm not a huge fan of out of state investing and I have 3 properties in Indiana, too many issues with being 2000 miles away.Also no one has brought this up but you said you moved in with your bf.

Maybe, that should be a met criteria, as others on here have the same issue. 

Some of my leases need to be updated, including increasing security when increasing rent; putting in clear violations (such as tenants using electrical heaters, which is a fire hazard); having a reliable attorney ready should any legal issues arise.

I'm wondering what is both legal and advisable in this regard.

Unless you have 10 properties going at once, you can manually update these without much issue.

Based on the location legal description, the zoning department should be able to tell you what you can and cannot do when it comes to removing the existing home and placing a newer mobile home on the land. 

Now that home prices have stabilized, every month you hold a NPL it becomes less valuable because homes are not appreciating and time costs money, as well as additional incurred expenses like servicing, FPI, legal etc.

I personally would set up a separate legal entity whose purpose is to manage STRs. 

This can legally protect your designs and ideas.

Has anyone run into issues in swfl trying to get builders risk policy to get a deal done?
