It just depends on the current quality/condition and expected future life of the carpet.

High price, normally not great condition, and rents so so low compared to purchase price....like $1000-$1200/side on $400,000+ purchase price. 

Remodeled the kitchen, bath, and conditioned the attic to living space before moving out and renting.

It can be a little awkward if the tenant is there or if the place isn't in perfect condition, but my feeling is that its more important to get the unit re-rented ASAP than to make everyone feel 100% comfortable.

During your walk through of the property you should be able to get an idea of the tenant based on the condition of each apartment, dirty, damages, etc.At the end of the day it can be challenging choice to make on keeping the current vs not.

Then its a matter of finding the best condition property, for the cheapest price.  

I roof here, a driveway there, an HVAC system there, a foundation repair elsewhere could eat through that easily.I would assess the condition of all major systems on each property and plan to have enough cash to replace each of them at the end of their useful life with some cushion for emergencies. 

I'm hiring an HVAC tech to check it and make sure it's in solid condition ahead of the winter season and ensure my tenants are in good shape and can stay warm. 

Is this to evaluate the condition of the house for cost of repairs?

If you're looking at a fixer you won't be able to use an FHA loan as they are super strict about the condition of the property at closing.
