Where to get unsecured 100k loan?

[John Mimms]

I am trying to sell a piece of raw land for 440k and I owe 177k. I have a guy that can put down 50k and wants to do a 5 year balloon. I have outstanding credit score and make 300k a year but only have 30k cash right now due to the plague. I can repay the loan in less than a year and really want to get the property off my books. Who/how would you recommend coming up with the 100k? Previously I used USAA previously for a personal loan for 100k but their new personal loan limit is 5k. Please help.
