makes no diff - if they make the interest only loan repayments in the first 3 years business should be going strong by then including Tanz I would suspect. Most financiers would expect some security so can't see the relevance of the question and as far as guarantee payment goes - well how much of a guarantee do you provide on your mortgage?.simply a great deal which hopefully will transpire within time frames provided then we're off and running especially given that production for the first three years has been accounted for.
