Unless you get lucky and they cover a big ticket item, they're not worth much.

The truth is other than individual items/scopes on a larger project, there is a good chance putting a standard $xx/SF to rehab will end in over or under bidding the job, probably by a large margin. 

I typically need to re-caulk some/all items between tenants, even if it has only been 1-2 years. 

If there's one item I can share with you, put the right people in place to take care of the entire process.

I would go ahead and make the claim for the items mentioned above that you feel were beyond normal wear and tear. 

Luckily most of the items were already in our reno plan.

Additionally it can usually be a good idea especially if second level to have a tile floor where the washer and dryer are and have an in floor drain system.These items can be an upfront cost but can generally pale in comparison to a water leak event. 

They're a luxury item that is a nice feature if the location and rest of the apt call for it, but you will never hear someone say "I can't stay here, it doesn't have heated tile in the bathroom".

Jewelry is a VERY HARD item to sell, unless you have some type of shop, jewelry is often faked, fake diamonds, fake gold, fake rolex's fake everything, and people are always worried about being scammed, and you have to keep from being scammed when buying.

Consistent with traditional contract terms, in order to qualify as an offer, the item or terms that are being presented to the home buyer must be items or terms that are capable of acceptance.
