Buy house with VA Loan (Loan Takeover)

What's up everyone. I am looking to buy a house in SA and was really hoping to find one sold by veterans/soldiers with VA loan. I understand that rates are crazy right now and not everyone wants to sell but if you know someone please guide me forward. I will reward you with a finder's fee of $1000 if we close on the house.

My hope is that if I get one I can take over the loan with lower rate and make a quick sale for market price.
