Buying land, whether commercial or residential, is definitely an expensive endeavor, even though prices have eased somewhat lately. This is exactly why finding a piece of land that you want and making an offer for this without conducting a land survey on the region is most likely the biggest mistake you can make.
Here's why it's very essential that you have land surveying done first:
Land surveyors can determine if you are actually getting what you're going to pay for. This means find out whether the sidewalks, trees, driveways and even the bird bath is the main property you're about to buy. Land surveying would also determine whether the neighbors are encroaching into the property, which would then mean you are going to have problems in the future with your neighbors.

Hiring a land surveyor doesn't only mean they know what you are getting or not getting - land surveyors will be the experts, and they might help with building regulations, wetland regulations, etc. Take note that these regulations can change anytime, but land surveyors ought to be updated on these regulations, or they will refer you to somebody who is.
What if the existing landowner (the one selling the land) can provide you with old land survey documents? You need to still hire your personal land surveyor determine if the boundary monuments are still set up. Also, land surveying done a couple of years back may not show recent changes to the land. If the existing survey is more than about ten years, you need to get a whole new survey. Technology and surveying standards are both better now and should supply you more confidence in the survey work.
Second, that survey was completed for that owner. He may have instructed the surveyor never to show certain things on the drawing. At the very least have a land surveyor go out and review the parcel with this particular survey in hand. We've seen numerous cases where a new land survey would save the buyer thousands so don't become a victim.
3D Modelling Alfreton 've heard lots of people say hiring a land surveyor is only unnecessary expense. I'll let you know what's unnecessary: the strain caused by paying thousands for something and ending up not getting everything you were expecting. When you are smart, you'd hire an avowed land surveyor prior to making any land purchases. Trust me, it's all worth it and you'd be glad you'd the land surveyed.
