Xavier, the health research question is well covered above by Keith, Barrett, Julianne and Cathy, so I will not relitigate it. I am a real estate professional, not a scientist, and I would rather point you to the part nobody has mentioned, which is the part that will actually affect your money. If the lines cross or border the lot, there is almost certainly a recorded utility easement. Read it before you buy. That easement is a legal right the utility holds across your property, and it typically lets them do things you might not expect. Enter the property without asking you. Cut or remove trees and vegetation in the corridor, sometimes aggressively and on their schedule, not yours. Restrict what you can build within the easement area, which often means no shed, no pool, no addition, sometimes no fence of a certain height. In some cases it also affects where you can plant. That is the practical difference between "there are lines nearby" and "there is an easement on my lot," and buyers frequently do not learn which one they have until after closing. How to find out, before you write an offer or during your inspection period. Ask for the preliminary title report or the owner's title policy. Schedule B lists every recorded easement with a book and page reference. Pull the actual recorded easement document from the county recorder or clerk's office. It is public record. Read what it grants. Ask the seller for a copy of the plat or survey showing where the easement sits on the lot, and how much of the usable yard it consumes. Call the utility directly. They will tell you the corridor width, their vegetation management schedule, and their restrictions. They are usually quite straightforward about it. Now on value and resale, which is the second half of your question. Yes, homes near transmission lines usually sell for less, and yes, they are usually harder to sell. But it is worth being precise about why. It is not primarily an appraisal formula. It is stigma, meaning some share of buyers simply will not consider the house regardless of what any study says. That shrinks your buyer pool. A smaller buyer pool has two effects. You get a discount going in, which is real money in your pocket. And you face the same discount and the same longer marketing time going out. So the question is not "is it bad." It is "am I being paid enough for the resale friction I am accepting, and do I plan to be here long enough for that to be worth it." If you plan to stay ten or fifteen years and you personally are not bothered, buying at a genuine discount can be a good decision. If you might move in three years, the friction is a bigger deal than the savings. Two things to check before you decide. Have your agent pull the actual sold comparables for homes on that line versus a block or two away, so you know whether you are actually getting a discount or just being told you are. And ask about any planned utility upgrades in the corridor, because expansions do happen. I am Zoltan Peresztegi and I work in Los Angeles and the South Bay, so Tinley Park is not my market, but I am glad to help you read a title report or a comp set if you want to post one, and I can connect you with a strong local agent in the south suburbs.
