Residential investors can wait for the market to do the hard work. Commercial investors who want growth usually have to build it themselves. Victor Kumar reveals the levers that lift a property's value and how recovering a few thousand dollars in outgoings can add six figures to a valuation.

Buying a commercial property is the start. What you do next shapes its value. In Part 5 of the Post Budget Guide to Commercial Property Investing, Phil Tarrant and Victor Kumar of Right Property Group ask how you actively improve a property's income and value once you own it.

Victor breaks down why commercial value is a function of its income, and how rent, lease length, tenant quality, recoverable outgoings, and vacancy can each move a valuation. They run through the strategies behind improving a commercial valuation: buying dependable income and holding, restructuring leases, repositioning the tenant mix, upgrading the building, and subdividing without disturbing a single tenant.

They then analyse why not every value-add plan can be delivered. Victor explains how a lease can block an upgrade or a change of use, using his own St Kilda Road office, where a tenant has kept renewing for seven years and stopped him from adding a second lettable space.

The pair also look at owner-occupier and SMSF strategies, including how renting a property back to your own fund can affect its value, and why the rent needs to stay at market value.

Finally, they look at how to build a portfolio around it all: one big asset or several smaller ones, spreading risk across tenants, industries and locations, and balancing commercial with residential and income with growth.
