Repair contingency- no progress has been reported

[Robert F.]

I am under contract to buy

Offer was made with inspection contingency 

Seller agreed to repair or replace furnace a week ago

I asked my realtor to check on the progress of seller and they have no real news for me a week later, other than an HVAC guy was on property- per sellers realtor

My loan is conditionally approved pending appraisal

I told my realtor I’m not ordering the appraisal until I am satisfied with the progress being made to fix/ replace furnac

Is that unreasonable? My realtor seemed a little miffed, but I have 17 days to get the appraisal done before closing and my MLO is confident we can get it done in time
