What would be an estimated total cost for 80's office remodel?
I purchased an office property that's been basically untouched cosmetically since construction in the 80's for appx $85/sq ft (hvac and roof were redone this century).  Anyone have a rule of thumb on costs of remodel?  I have a contractor working on it I've used on residential projects but it's going glacially slow and I'm starting to think he's in over his head and underbid the project.   Four suites appx 2k sqft each suite and a shared lobby/restroom area of about 500sqft with stairs.  

I have a national tenant in a 7.5k sqft retail/warehouse combo on the other half of the building covering my mortgage  so I'm not in a huge rush but I'd like to get this wrapped up and I'm frustrated with my current guy who's been in there since August and only has one suite done (poorly, in my opinion).

Eastern Washington since I assume there's  regional variations.
