Don't get hung up on the asking price. This new breed of "recreational/Hunting land specialists" realtors will inflate the asking price 25-30% over market value. That is how they get the listing.
I would be concerned with having to use MFL just to afford the property. It will probably limit some of the improvements you could do that would improve habitat. But if it works for you then worth considering.
Don't worry about "holding" deer, that is a fallacy especially on a property this size. With those marshes east & west, consider making it a destination & travel corridor area with increased lower cover such as shrubs. Plant shrubs & pines on the perimeter to reduce sight lanes in those pines. Improve the food plots to draw in the does and the bucks should find them.
