There are usually several factors to consider, including traffic flow, and you need to decide in advance which are the very best times for someone to see your house at its best, and arrange your viewings accordingly. 

Try and avoid school times, if you live anywhere near a school and parents have a tendency to park near your house when collecting and dropping off, or bin days, no street looks nice with a row of wheelie bins waiting for the bin men.

As well as these times to avoid, think about when your home actually looks its best? When does the sunlight stream through the kitchen window? Lots of buyers are keen to make sure the garden is well lit at key times of the day, so show yours off and arrange the viewings accordingly.
