Credit unions, banks, mortgage companies and private lenders.They all had the same answer.

Id go right into looking at local credit unions and small community banks for HELOCs (lines of credit) so you can have a lower blended rate and draw/payback as you please.For the 3F - Since this is free and clear, you would only be looking at 1st position options here in the world of financing.

Private lender will be close to a credit card interest rate for them to finance something like that.
