A Demanding Riley Riddle

Another Riley riddle for you, but with a slight twist!

Take two from my prefix, a large plot of land it is
Take five from my infix, it becomes hers or his
Take two from my suffix, there's no better can you do
Take all together, it's something you must see to

Alas, the three smaller parts are missing two things
Prepend the first and third so meaning you might bring

Hint:

These 'fixes alone, they just make no sense
But still, the answer is not purely pretense
No matter how many we take, whether it be two or five
The last line tells us all need two more for meaning to arrive

• I keep reading that title as "A demanding Ridley Riddle" lol – dcfyj Feb 12 '20 at 19:13
• I've realized a frankly ridiculous mistake in my original puzzle that made it not a good puzzle at all. I've modified it so as to preserve the spirit of the puzzle -- the answer and method of solution are almost precisely the same. However, if folks think this should be closed I will certainly do so. I apologize if I've wasted your time. :( – Tonkleton Feb 12 '20 at 23:35
• The puzzle says two, five, and two; the hint differs. Which is correct? – mbingo Feb 13 '20 at 0:04
• Changed the hint to remove the ambiguity. – Tonkleton Feb 13 '20 at 18:31

The final couplet is telling us to...

... prepend AC to the specified 'fixes.

Accordingly,

"a large plot of land" is an ACRE
"it becomes hers or his" when they ACQUIRE it
"there's no better can you do" once you've ACED something
