Advice needed from realtor

Open house Saturday, final and best offers by Monday… first time home buyers, loved the house and felt immensely pressured w this tight timeline. we had very limited information before entering our offer, definitely our mistake.

My husband and I offered 395K on a home that was listed for 400k. Offer was accepted. Sellers are moving out of state and are trying to push this through asap.

We still don’t know the age of the roof and we were given incorrect information on the solar panel situation. We continued our research post offer and have learned they did not pull permits for plumbing or electricity in the detached barn that someone is currently living in.

We are considering recinding our offer and offering less…. Our realtor advised against that. I am going to the town to look through building permits shortly. We are overwhelmed and are not receiving any info or advice when asked. Unfortunately our realtor is a family member- they are retiring in February 2025 so they are already mentally checked out and not helping the way we need help.

Realtors- what would you advise your clients to do in this situation?
