Advice on maximizing equity in investment properties

[Chad McGibbon]

Scenario:

Client owns 4 rental properties. 2 SFH and 2 duplexes. One of the duplexes is actually a lease option with a 30 year note. Total owed on all properties is around 350k or 300k without the lease option duplex. Total value of all properties is right around $1m so a good amount of equity.

Prop 1 SFH: mortgage amount around $950, rented at $2175

Prop 2 SFH: mortgage amount around $900, rented at $1725

Prop 3 Duplex: mortgage amount around $1000, rented at $1400($700/side)

Prop 4 L/O Duplex: mortgage around $800, rented at $1850($925/side)
