County site assessed value on Land- is this accurate?

[Account Closed]

I just bid and won a New Jersey Tax Lien for a 1.5 acre piece of land next to an owner primary home parcel. The county site has an assessed value of the land over $100,000. The owner’s parcel next door is assessed at $200,000.

Is it necessary to check that assessed value by another method? Should I contact a local realtor to check it out? What other ways can I check this?

I know it’s too late and I probably should have asked this question before buying the lien. If anyone has ideas and/or comments on my purchase - please feel free. I paid a few thousand for the 1.5 acre land.

Thanks!
