1. Land may be in an HOA or improvement district. Therefore, fees may be associated with this type of neighborhood.
2. City utilities may be unavailable. This would require installation of a well, septic, etc.
3. Sometimes it's difficult to find the exact location of vacant land. We might estimate the location using a nearby house number, so buyers have a general reference point to use for GPS navigation. Other times, we might predict the location using parcel maps with similar parcel numbers. You can have a survey done at any time to find the exact location.
4. There may be boundary disputes with neighbors, or land may require an easement to access. These issues might be negotiable with adjacent land owners.
5. We may estimate land size using the metrics of nearby parcels. A survey can also provide the exact size and dimensions.
6. A piece of land may be too small to build according to code.
