Hey Joey, Here is my understanding of the subject:Key Components of a "Subject To" Offer:Clear Identification of Conditions: Clearly state the conditions ("subjects") that must be satisfied for the offer to be binding.

we weren't aware of that and got slapped with a huge tax fee unexpectedly!

For me, everytime I think my life is on a straight road next thing I know here comes an unexpected twist and turn.

I understand unexpected things come up as the work progresses, but how is this typically handled?

Long story short - you cant just take the current effective tax rate and apply it linearly to the new price - there are fixed and variable components of property taxes so it wont scale like that. 

Things don't always go as planned so plan for the unexpected.

That means more expensive and less profitable and, personally, I wouldn't invest there because of the sargassum issue but you might care less about it because of the lifestyle component in your case.4.

I don't know if I agree with your philosophy about maintaining some components and others not.

Heaven forbid something unexpected happens. 

I like the operating-holding strategy, but the only side of that which is simple is the operating component.
