Landlocked real estate is a parcel of land surrounded by land owned by others. As a result, legal access to such land is not possible. The only way to access the land is by crossing the property that is owned by others.
For example, there is a vacant lot behind an apartment. The only way to get to this site is through the land through the apartment.
Another example is a lot behind a huge commercial complex and there is no direct road to access the land and the only way to get to the land is through the commercial complex. In both examples, the land is known as landlocked property.
These types of plots do not necessarily remain landlocked. Buyers of this type of land may negotiate easements or rights-of-way with neighboring land or property owners.
This would help the buyer to gain access to the property. The time taken to get an easement or right of the way completely depends on the neighboring owners.
If the owners are reasonable and helpful, it could be an easy process else you might need to take a legal route which could be time-consuming and costly as well.
