Are level floors a big deal for ARV?

[Shravan Gali]

Hi Folks, Can someone please help me with my dilemma here? 

The floors in our property (which is going through rehab) are not level. We have an option to add a transition material(cheaper option) or we need to level the flooring for whole house - My GC says it would increase the budget by $3500 and my realtor said that this is a big deal when it comes to getting full ARV when we sell.

Is this a big deal? Appreciate any help I can get here to make the decision. Thank you!
