I have several loans that I am ahead in the repayments, to the tune of about $90k. I'd done this to ensure we have no problems meeting payments through the build, but now I'm considering paying our next progress payment by redrawing on these loans, but I'd prefer not to make seven individual part payments which is messy for the builder. I'd prefer to transfer (technically I guess it is a redraw) the prepaid funds from six loans into the seventh loan, and then make one payment to the builder. I have a spreadsheet for each loan to allow me to recall what any redraw was used for, so I'd have good records, and it would show redraw funds going from six loans into the seventh loan, with a lump sum coming from that loan for the progress payment. Would that mess up the deductibility of any of the loans?
