The test for deductibility is the nexus between the expense and the assessable income that flows from it. I think paying lmi and parking the extra funds in a savings account doesnt cut the mustard
Well according to the Genworth website: http://www.genworth.com.au/homebuyer-centre/homebuyer-tools/lmi-premium-estimator/
Option A LMI: $3,213 + $2,652 = $5,865
Option B LMI: $10,176
But Option B wouldn't happen because there's 2 properties - not 1
It might legitimate but it's not 100% clean... As Terryw said it's a little strange why you wouldn't finance the entire IP and PPor on one loan in the future to possibly save on LMI and avoid paying so much upfront
