How do you calculate real estate development costs?

• <div><p>You should always calculate real estate development costs on a case-by-case basis, so there’s no specific formula to estimate your total. You should speak with a local construction manager to see what you’ll need to do in terms of clearing and leveling the land, connecting utilities, and pulling permits for construction. A professional will be able to get you an accurate estimate for land development. </p></div>

Q: What information can I find in a land survey report?

• <div><p>Land survey reports have a boatload of information relevant to several scenarios. Here are the types of information contained with a survey, though it depends on your chosen type of land survey. Exact boundaries and dimensions of a given property General topography, including both natural and artificial landmarks Location of utility fixtures, like water mains Confirmation of any easements or encroachments on a piece of property Assessment of land elevation to buy flood insurance Updated information to add to a pre-existing property map</p></div>

Q: How do I know how deep my well is?

• <div><p>There are a couple of ways you can determine the depth of your well. One method is to use a device called a well sounder. This tool has a long measuring tape containing a sensor to alert you once the end reaches the water. </p><p>Or you can DIY it by using a long tape measure with a half-filled bottle of water attached to it. Lower the tape measure into your well. Once you feel tension on the tape, you&rsquo;ll know the bottle has reached your static water level. This will give you an approximate idea of your well&rsquo;s depth.</p></div>

Q: What’s the difference between a land survey and a boundary survey?

• <div><p>A boundary survey measures the boundary lines of the property, only the length of each property line and their locations. A land survey includes a more in-depth measurement of the property, including the heights and depths of the terrain measured by a topographic survey. A boundary survey is typically the most cost-effective method for marking and measuring property lines.</p></div>

Q: How do you prepare for a land survey?

• <div><p>To prepare for a land survey, you must thoroughly check your land surveyor&rsquo;s qualifications, reviews, and fees to align with your expectations. When it is time for the survey to be conducted, ensure that you have all your documents organized and available, know and mark your property lines, and inform your neighbors that the survey is happening. </p></div>

Darvin and his crew did a fantastic job of land clearing of my property for a reasonable price. His crew were out working and got the job done quickly. They cleaned everything up around my property and treated it as if it was their own. I will definitely call on him again.
