The survey on a house takes between 2 to 4 hours from start to finish depending on the size of the property.
It can take a few days for the surveyor to be available to come out and do the survey of the property but the actual survey on the property or house takes at most 4 hours.
Whenever I had a survey done on a property it took 2 hours to complete and it's usually pretty quick and can be even quicker on some smaller properties.
I've seen some surveys take as little as 30 to 40 minutes on smaller properties that don't have much land to it.
A survey is always a good thing so that you know where the property lines are and to avoid a fight between neighbors over property lines.
Having a survey done on a property costs between $200.00 to $500.00 per survey depending on size of property and the surveyor.
