IRCC don't ask any such specific Document
However I am getting your point you wanted to show the Tie up with home country and you wanted to evaluate the value
Then also for Tie up you do not need to show the evaluation of the property your parents have , Just property 2 pages (where their names are mentioned are more than enough)
In case you wanted to show the Value just to show fund IRCC Consider Liquid money Only
Good Luck
