If official records show that KPK (Koretsky family) does in fact hold the mortgage to the Maple Grove Raceway property, then they will repossess / foreclose on the property if and when IHRA defaults on the loan or lease payments. They need to begin the legal process to repossess immediately before Cuttell Motorsports LLC dba IHRA files for bankruptcy which would be detrimental to the Koretsky family.
They need to take MG back from IHRA and either run it themselves or sell it for 100% cash to somebody else.
I doubt if NHRA is interested in buying Maple Grove or holding a national event there in the future.
