Assignment with commercial loan?

[AnDinvstrs]

   We have a home under contract and the end buyer is using a commercial loan.  Does anyone know if there will be any problems with using the assignable contract with the buyers commercial loan?  The buyer is also a realator.  We used an assignment contract before but the buyer was a cash buyer for that property.  If you have any info or advise on this issue please reply back.  Thanks for your  .
