On a 203k loan is it common to ask the contractor for receipts?

[Redgy Saint-Germain]

I would like to compare projected materials cost vs actual cost for my current 203k renovation to aid me with my future offers and estimating ARVs. I feel nervous about asking my contractor for receipts because I wouldnt him to think I don't trust him but I also need to make sure the budget is well spent. 

Am I overthinking this ?

I'm assuming the 26k all related to the above?  

If you have a consultant involved, I wouldn't worry too much. If something odd happens, absolutely ask. But you had to review the bid (which broke out materials/labors) before you accepted it. Research cost then. 203ks are hard enough for contractors, especially if they don't do it often.
