Bueller ... It has already been commented on; however, I can't stress how important a good attorney is to buying property. I have bought & sold quite a few properties (with & without a building on it). The only time I had an issue was when I trusted the advice of a Realtor on an easement, turned out this guy was beyond his pay grade.
The attorney will help write the offer and insure that the contract is enforceable.
I would make sure you have an attorney review the easement to make sure you fully understand the type of easement, restrictions, ability to maintain, and any limitations on improvements. You want to make sure you can maintain or deliver electrical, cable, phone, utilities, etc back to your property. Understand what the Title company is insuring on the property & easement and what if any exceptions they are taking.
Have them complete a very thorough title search and secure a reputable Title Company and Surveyor. I would offer to split the cost of the survey with the seller. It is insurance for both of you as he is clearly communicating the property boundaries and you know what you are buying. Make sure you have the right to inspect and approve the boundaries.
A good attorney will probably run $1000-2000 from start to closing. Remember, your attorney is the only one protecting your interest in the transaction. This is especially important if you plan on re-selling the property. You don't want a future buyer to discover issues that were not uncovered in your purchase.
There is always risk, but putting the right team together can help minimize it.
Good luck!
