NOT LOOKING FOR COMMENTARY ON MARRIAGE/RELATIONSHIP AND HOW WE CHOOSE TO SPLIT THINGS - THANK YOU!

Is 100% of the real estate required as SBA 7(a) collateral if the collateral shortfall is greater than the equity in the primary residence?

I am married and signed a prenup. Through that agreement, my spouse and I each SEPARATELY own 50% of our primary residence and split the related mortgage. I received mixed messaging on whether my spouse's 50% (not marital property; spouse owns real estate separately) is required as collateral for an SBA 7(a) Loan. I alone have less than 25% equity in the primary residence.

If someone has a specific clause for me to look into, that would be very helpful. Thanks in advance!
