Correct...and this is where I'm lacking in the balls department...too worried **** hits the fan and I won't be able to pay back the loans with the dividends.So the appraisal costs you upfront ~25% of your interest cost on the mortgage and you pay a crappier rate. Assuming you are ready to pull the trigger and spend the money, I would do mortgage. If you are going to think about it for six months, I would wait until I was ready to pull the trigger (or if you are feeling ballsy, dump mortgage into bank stock until you need it, very low chance you lose a significant percentage).
I could always top up the TFSA, RRSP, RESP and just pull back from TFSA when needed.
