Several mid-range builders have started included it as a standard option, so it's becoming more of a norm in that 250k+ price range. 

I expect that values will continue to rise in Florida but do investors expect that the extreme price appreciation this last year may flatten over the next few years or given the migrations and low inventory and low rates folks still believe at least average appreciation may be realized ?

Relationship with wholesalers will come along the way but in this current market inventory is so tight, everything sells (sometimes over market) so the timing is not ideal to target Wholesalers as your only source of deals. 

We have more buyers/renters than we have available inventory in every category.2) Have your money ready to go, both cash and financing.

Go on Airbnb and search for 3+ bedroom houses for short term rental, you will quickly see the lack in inventory.

This house was in a great area and at a price point that would sell quickly with very little competing inventory.

The box did state that the product was only good in the temperature range from 50 to 70 degrees but I still felt like I got ripped off.

It's always a range, so I would figure out what that number is and decide where in that range you want to be (higher end with max rents and higher vacancy with tenants leaving for better deals, lower end rents that's sticky for tenants or somewhere in the middle).

The real impact of a highly priced market is that those prices might knock deals out of the range of your cash position. 

This area is so hard now to find property within the 211-220k range.
