Seller carry 2nd mortgage

[Njoukeng Nanfack]

Hello, Help needed:

• l am under contract to purchase a property for $800k. Seller is going to carry a second mortgage for $300k. l can potentially use my VA loan for financing with zero down payment. The property currently has a county-assessed value of $849k and may appraise for more.
• Is there any possibility for me to structure the seller financing + bank loan such that l can end up getting a check at closing?

Thanks
