80/20 split first mortgage and need to refinance !!! HELP
You might want to try a Wells Fargo Harp loan.

Can I cash out up to 125% with Harp 2?
No you cannot. The program is for existing first mortgage to lower interest rate or term or both.

After refinancing, will my loan still be a freddy mac or fannie mae loan, or don't know?
C, after you close on your refinance, you will receive a letter from the lender notifying you if they sold the loan to Fannie Mae or Freddie Mac. You can also call your loan servicer to obtain the answer.
