I think the biggest opportunity is that you can re-structure your financing to clear off your Carlton street mortgage in full.
Transferring the debt load on to your rental creates improved tax benefits (by reducing your "profit) - while actually creating a net monthly benefit of $643. (643is the result of the elimination of your $778 P+I payment on carlton MINUS the $135 INCREASE in monthly cost post refi.... 778-135= 643)
643 per month = $7716 per year of new operational income. -- adjusted for taxes this is as if the restructure will create an annual raise of $11,000.00!
