Keep in mind, using the Wetlands Mapper and/or the Web Soil Survey is NOT the same thing as hiring a wetlands consultant and/or having the USACE do a delineation on your property (so realize, there are no guarantees with this approach). However, if you're just looking for an educated guess, both of these online tools can be used as a starting point.
Be sure to use visual tools to tell the story of your lot or land in your online listing in a beautiful and compelling way. You can’t show photos of a kitchen or great room, so be creative with your lot or land photographs. Use attractive photos of the home site, natural features of the land, the view from your property and even community amenities (see tips for creating great photos for lot and land listings). Use maps and surveys to show the property boundaries and where it is located. Learn more in our related article about 5 tips for selling lots or land with online listings.
Very good question, Trevor. We plan to do a blog article on this subject soon. You are pretty much on the mark with your example of 25% of the final to-be-built home’s value as a rough guide to a lot’s value. You’ll see that some markets use different valuations (even within the same city or region), but in many markets an estimation of the value of the lot generally can range from around 20% of the home value (for more rural or lower price point homes) up to around 30% or more (often for higher end communities or for urban/infill areas with less lot supply and higher home prices). Of course for some lots/properties these rules simply don’t apply, like oceanfront lots or land with other unique characteristics.
I am currently listing a 10 acre piece of vacant land, which is zoned R-1, in Hesperia, California. The seller states the property can be zoned commercial. I spoke to the planning department and they stated it is zoned residential. My client is totally convinced they are wrong and it can be switched if someone pitches a commercial rezoning presentation. What is your take on this?
