They want to see a certificate of occupancy, which I am told only applies for commercial property.

If a seller is advertising his leasehold interest for his specific unit (stock certificate) for $50,000 ... how do I determine the value of his asking price?  

After certification, you can send all documents to closing attorney.

Any information you can offer to about how to access a list of delinquent taxes, tax deed sales, tax liens, how to find out which firm handles the tax seizures or foreclosures,or tax lien certificate sales would be incredibly helpful.Thank You In Advance,Kayla

I've informed him that wouldn't be the case because the liens would prohibit the transaction from going through if there are any.My due diligence tells me there are back taxes for 2 years due and that a bank purchased one of the certificates.

The contract that we received specified that it was a three unit, so seller would need to provide legal certificate for a 3 unit.  

Did you opt for management by members, which requires that you disclose your members in the publicly filed Certificate of Formation?

Be sure to check out the Short Sale and Foreclosure and REO certifications as well.I wish you great success.

If you location requires a certificate of occupancy before someone can live there, you will need to get the proper permits and finish up the inspections to get the COO.

You should video record this as well.To your specific question, It really depends on how hard you want to play.If it really is just a communication issue, work through it and explain you are unable to do your due diligence without the certificates and copies of any leases and would be unable to close the sale due to the seller's deficiency.That is the softball way.If you want to go hardball you can send him formal notice reminding him you relied solely on his representation of the condition of the leases.
