Put non contingent offer - closing jitters

[Navjeet Singh]

Our Agent knew we were beat up buyers since we lost 3 homes prior and switched agents..The agent influenced us to go non contingent offer waiving everything… if we wanted to win the house. We went with highest offer got a counter asking $20k more and reluctantly signed. We really stretched ourselves thin. 

we did not perform our own inspections because we were busy raising finances .. and our agent insisted we use the same company who did the initial inspections to “get a report in our name” .. we went for visual inspection with our agent and found the master bathtub was  upside down — they said there was a chip and seller was fixing the tub. Our agent was rushing us because she said she had an appointment. But when we found the issues she decided to stay back. 
 

This raised some doubt and we communicated to our agent that we are not satisfied but she kept insisting “there’s nothing you can do” and “you went non contingent” 

Then later she sent an email saying we passed the 17 day inspection period which we didn’t know about.

I asked I want to arrange my own inspection and she said .. “what are you going to find?” And there’s “nothing you can do you went non contingent” .. and she veb said “you can do all the inspections you want after you close and move in” 

She insisted we either “get a report in our name” from the same inspection company or “call the plumber who fixed the leaks prior” 

Now 2 days prior to closing agent sent us a disclosure saying we waive all inspection rights - home inspection waiver , wood destroying pest waiver etc. 

we felt remorse of overpaying in first place and we are not sure if we are making a mistake closing this home with the whole inspection thing. The home has been sold 4 times prior built in 2003.

What should we do at this point? Earnest money is likely not going to be refunded if we back out now.
