If not, is there a master plan in which the municipality has indicated a desire to have your property zoned as you'd like to see it?

If you have no desire to actively pursue other investments where you make more than a 2.8% return, then by all means pay it off faster.TYFYS and best of luck!

Most of the ultra wealthy individuals sacrifice a lot to obtain their wealth, and I won’t make those same sacrifices.Similarly, I don’t desire to have 5% body fat because I don’t want to put in the effort required for it.I understand that ultra wealthy is subjective, but the main point stands. 

Purchase price: $295,000 Cash invested: $50,000 Single fam home, desirable neighborhood.

Tampa for example, the most desirable STR's are also very desirable to owner occupants (near beaches, near downtown, etc). 

If the desired zoning is next to your property, it is easier to get rezoned. 

(Starbucks / yoga studio / craft brewery /boutique cookie,coffe or ice cream shop  are the easiest targets)-Activation of dormant retail sites-Increased foot traffic For B to AAbove also apply-Home valuations (are homes in the increasing at rates above nearby or similar neighborhoods)-Is it walkable or are projects in place to make it highly walkable for residents-Is it near highly desirable activity centers -is it unique (for example - Can it get historic designation)

Also make sure to build on a property located in a desirable location with larger pop density and if holding for rentals, charge median rent for that market as lenders want to see a bigger pool of buyers/renters available to occupy/sell. 

We have one other mobile home park and this property will determine my desire to buy more or sell.

The fact that you can could create that desire to move.
