If you’re looking at a vacant lot in the middle of the desert or near the top of a mountain with nothing around for miles, you will probably want to verify with a professional that water will be accessible if/when you need it (and if your only option is to have it hauled in by truck, you'll want to get an idea for how much this will cost on an ongoing basis).
Also note that many landowners think they “own” all of the land along the roadway in front of their property, but often that land along the existing pavement is owned by the local government or DOT as part of the public right-of-way. Mailboxes, landscaping, fences and walls often are built in the right-of-way, but will need to be removed or relocated for road improvements. Confirm with a survey where your property line actually ends along the right-of-way.
As for pricing, your suggestion of $20,000 x 98 seems high for a sliver of road frontage to add a turn lane. Granted, you have the right to try to sell your property for whatever you think it is worth (unless it is a government taking for market value, or if you just don’t own the property in the first place), but that does not mean someone will buy it if it is overpriced. The developer likely has other options. Usually valuations in a situation like this are based on an appraised (or negotiated) value per acre or square foot, and then a survey determines the precise size of the sliver of land that is being conveyed at that rate.
Great list of ways to reach potential buyers Seth! If someone does ALL those, they’re very likely to get their house sold. We Buy Houses investors can be a great way to sell your house fast if you are short on time or don’t want to mess with the hassle. Otherwise offering the seller financing option can be a game changer and even more profitable for sellers. If you’re in a position to offer that, be sure to vet your buyer for their ability to make good on the payments. Thank you!
Rule #18: Before traveling to view a promising parcel, check the county assessor’s website using the parcel number. Some are VERY helpful, containing all sorts of information such as what areas are known for landslides, flooding, wetland/buffer areas, contamination, noxious weeds, etc. The sites also give past purchase pricing and tax information, and sometimes even if there’s been “issues” with the land (such as a previous owner building unapproved structures which they may have had to tear down, leaving a foundation for you to deal with).
Hi Colt, whenever I buy landlocked parcels, my offer is VERY low (because practically speaking, if nobody can access it, it might as well be on the moon – which isn’t all that useful UNLESS someone can obtain legal access). One way to prove that it’s landlocked would be to find a parcel map of the property – and I explain how to do that in this blog post: https://retipster.com/property-pictures

Consider your own needs when pricing, and understand how pricing could impact buyers’ interest. When selling real estate, you sometimes have to choose between getting the highest price and possibly selling quicker. Plus, your pricing may be influenced if you need to sell for financial reasons. In addition to your own situation, pricing your property ultimately requires an understanding of the land market as a whole, why people are buying lots or land in that area and who these people are. A good real estate agent with land expertise can help greatly in this process.
