Yes I spend time in Florida on a regular basis. 

Yes the lack of identical apples-to-apples comps has been an issue in the area for years.

Trying to read between the lines it sounds like you have a regular owner occupied homeowners policy in place on a rental property. 

Our mortgage brokerage works with real estate investors all across the country who face these same decisions regularly.

Transitioning from builder’s risk to a regular property insurance policy might be the way to go if the sale takes longer than expected.

Maybe you could extend the closings with some additional earnest money (even if you release it) and buy the time so you can simply do a regular 1031 exchange.  

Be careful not to place your identity in your age/success in RE.

I Joined Jeromes Buying land and building homes program back in 2019Heres my opinion on my experience....First and foremost He offers two different programs. a 6 month program and a 12 month program.BOTH PROGRAMS ARE EXACTLY IDENTICAL THE ONLY DIFFERENCE IS:You can choose to have the weekly mentoring by Jerome once a week for 6 months or 12 months on a zoom call and you can have access to a private networking group of real estate professionals whether that be (realtors, contractors, brokers, Private/Hard money lenders, loaning institutions, Surveyors, Engineers, Zoning Board members in different municipalities, pretty much anyone you would need to get a project completed) for either 6 months or 12 months.6 month program will run you $5,997 if you decide to pay all at onceor you can make a $2,300 payment every 2 months totaling $6,90012 month program will run you $9,997 if you decide to pay all at onceor you can make a $3,000 payment every 3 months totaling $12,000I decided to join the one year program and chose the payment option as i figured within 6-8 months i would have my 1st project completed therefor my last two payments would essentially be covered by the return on investment from that project.PROS:The group is really a family oriented space where you meet a vast variety of people from all types of background throughout the country and other countries that are doing business just like you.

If you plan to manage remotely, then find a good PM or have a trusted team that can inspect your property regularly - and be ready to pay them.

Also, be aware that your identity will eventually come out depending how far litigation goes.
