The hard part is finding the deal and execution on the rehab. 

There was a glut of high end, executive homes and prices were stagnate on the upper end of the market for many years. 

Create a bulletproof plan and then execute!

Is it properly executed (in FL leases over 1 year must be witnessed).

The IRS will have to decide if they want to redeem, if this is the case, they have to execute the sale and they will have to pay back what you have put in up to this point to include your lawyers fees, etc.

I am excellent at event planning, coordinating and execution but I need to know numbers to choose a proper venue.Give this post a shout with your location!

With a lot of groups competing to acquire assets, sellers highly favor groups that they are certain can execute. 

Great points, great analysis by @Mike Bonadies.One thing I will point out is that people don't generally dump "gold mines" -- if the property is making money hand-over-fist, then there's no reason to sell except if the seller is executing an exit strategy or maybe priming for a 1031 exchange.

I’m an executive assistant to the CEO by day and the landlord by night.

For all of the reasons discussed above, executing a real estate deal via text isn't the most strategic move in every engagement, but yes it is possible to form a legal agreement over that medium.
