My advice is to review the loss making properties with a view to getting more rent and turn them into positive cash flow properties.

Suggestions –
add some furniture.
Find short term tenants (holidays, workers in transit, migrants, visiting professionals, people having homes renovated, people visiting hospitals or local doctors)
add a room or extra accommodation
maybe the rent is too low anyway

This may mean some work – (time investment) but it has always worked for me
