Is four years too long to spend with a realtor?

My husband started a new medical practice in Rochester Ny back in 2020. So we rent a condo there for him. Our family home is in PA with 3 years left for our last child to graduate HS before I move permanently to NY. We have been working with the same realtor in Rochester since 2020 have made multiple offers over the 4 years to no avail. He’s nice. My husband likes him. We mostly find our own listings to view online, occ he sends an email with a listing. But I’m frustrated! I don’t know what to do here. We made an offer last year on a house that would work for us for full price $895,000. The seller turned down our offer saying he now wanted 1.2 million because he thought he would get a bidding war. He didn’t get any other offers, so he took it off the market. He put it back in the market this June for 1.1 million. We did not know it was back on but I feel our realtor should have known and told us. It sold a few days later for $900,000. Only $5,000 more than our previous offer! This past week called our realtor to ask about an home that just came on the market wanting to know the area ext, our realtor sent us an email back saying it looked perfect for us. He Set up a showing for 2 days later we were so excited and planned to do whatever we could to get this one. Then the next day we were notified that an offer was accepted so no showing. We were heartbroken..until my husband mentioned this area to a co worker at the hospital who said oh yeah that house is 1/4 mile or less from A Nuclear Power plant. What?? How could our realtor not know this info? We would never been ok with a nuclear pop so close to a development and not have gotten excited then heartbroken then confused here. I feel like our realtor should have told us about this before the showing was even set up as I asked about the area since it was in Ontario and not Rochester. Something def feels wrong here. I know we have 3 years left to find something but we do t want to be stuck on that 3rd year, plus me having to look everyday on Realor.com, I gave a job myself and college kids, a hs kid, it feels like I’m the realtor not him. And neither is us are getting anywhere!!
