Keep in mind that you cannot schedule appointments directly behind a previous appointment. An example, you see that I have busy time from 2:00pm to 4:30pm, you would not be able to schedule at 4:30pm you would be able to schedule for 5:00pm.
Also keep in mind that we figure about 1hr and 15 minutes per 1000SQFT of home. And that the sun gets to a point we cannot properly scan in most places at 7:15ish.
For example: To estimate a 1700 SQFT home would be 1.7 times 1.25hr equals approximately 2hrs and 10 min. I put in a little “slack” because not all homes are the same.
