Average house, 3 br 2 bath, 2.5 - 3 hours inspecting and 2 hours to write the report.
Minimum 1.5 hours and 1 hour to write on a tract home where I have inspected several in the past.
The more photos, the longer the time to write.
If I have 1 inspection that day, I take longer.
I suck at typing.
I will justify buying a new laptop if it has features that will save me 5 minutes per report, but thats because I like buying new laptops.
