Routes with a variable

Change route rule to

PHP Code:

$route['property-sheet/(:any)'] = 'home/property-sheet/$1'; 


In your views or places to show url

PHP Code:

echo site_url('propert-sheet/'.url_title(property->title)) 


Bonus:
I would suggest you have another column e.g slug
Where you will save URL formatted titles so that you don't have to call url_title() every time 

Instead your code would be

PHP Code:

echo site_url('propert-sheet/'.property->slug)
