The BELOC is not a product for everyone nor all situations, even though it does have significant benefits if it does fit your needs.I just want to state that I would put more emphasis on those who have actually worked with them rather than speculation of them as a lender.

There was a GLOBAL point, in the GLOBAL answer to this ALL-ENCOMPASSING question, that as said at start relates to O.P. question.
