First commercial property purchase? 3 finance mistakes to avoid
If you’ve built a residential property portfolio, the move into commercial property might feel like a logical extension of skills you already have. Property selection, market timing, yield analysis, debt management — the muscles are already built. The mistake I see many of my first-time commercial clients make is assuming that financing follows the same logic. It does not, and the gap between residential and commercial lending is where deals get repriced, restructured, or lost.
Having helped more than 3,300 Australian property investors and business owners since 2009, a meaningful share of my weekly conversations with new clients are residential investors making their first commercial purchase. These are the top three mistakes I see show up again and again.
Mistake 1: Reading the lease for rent, not for risk
In residential lending, the lease is paperwork. The lender wants to see it exists, glances at the rent figure, applies a 75 to 80 per cent shading factor, and moves on. The borrowing decision is anchored on your personal income.
Commercial lenders flip the hierarchy. The lease is the asset. The metric they care about is the debt service coverage ratio, which compares net rental income to proposed loan repayments. Most lenders look for a DSCR above 1.25, meaning rent must cover repayments by at least twenty-five per cent. But the headline number masks where the real assessment happens: lease term remaining, tenant covenant strength, rent review structure, outgoings recovery, make-good provisions, option periods, and the gap between passing rent and market rent.
I have seen identical-priced properties with the same gross yield receive completely different lending offers because one had a national tenant on a seven-year lease with fixed reviews, and the other had a local operator on a rolling two-year term. Same property type, same suburb, same yield. Different deal entirely.
A vacant property sits at the extreme end of this. Without a lease, there is no rental income to assess against repayments and the DSCR test cannot be performed in the normal way. Many lenders will not consider a vacant commercial property at all. Some might, but typically at lower LVR, higher rates, and on the basis of a leasing assumption rather than actual income. If you are buying with vacant possession because you intend to occupy the property yourself, that is a different conversation again. Either way, vacancy is the scenario where the lease genuinely is missing, and the deal economics change accordingly.
Mistake 2: Anchoring deposit expectations to LVR rather than to the lender's appetite for the asset
Experienced investors know commercial LVRs run lower than residential. Most assume sixty-five to seventy per cent and budget accordingly. The mistake is treating that as a single number rather than a range that moves with the asset.
A standard metropolitan industrial property with a strong tenant covenant and a long WALE will attract seventy per cent LVR from multiple lenders, occasionally higher with a specialist lender if the deal is otherwise strong. A neighbourhood medical centre or multi-tenanted office in a major city sits in a similar band. A regional retail property, a single-tenant specialist building, or a property with environmental or compliance concerns can drop to fifty to sixty per cent — sometimes less, depending on lender appetite.
What this means in practice is that two investors with identical deposits can find themselves shopping for completely different property categories without realising it. Working out your LVR ceiling before you make an offer is the most under-appreciated piece of pre-purchase work when you're arranging commercial property loans. It is also the conversation that costs nothing and saves the most money.
Mistake 3: Going to your residential lender first
This is the most common and possibly the most expensive. Your residential lender knows you, holds your existing residential security, and has done good work for you over years. The natural assumption is that they are the obvious starting point for the commercial deal. They are usually not.
Commercial credit policies, risk appetites, valuation panels, and turnaround times all sit separately to residential, even within the same bank. The Big 4 vary widely in commercial appetite by asset class, location, and deal size. Regional banks can have stronger commercial divisions than residential investors realise. Specialist commercial lenders, who do not advertise directly to residential investors can carry the best offers for non-vanilla deals. The same logic applies if you are considering SMSF commercial property loans, where the lender panel narrows further again.
The investors who get the best commercial outcomes treat commercial lender selection as a separate problem from their existing banking relationship. The investors who do not are the ones who tell me, six weeks in, that their bank has declined the deal and what are their other options. They almost always have other options. They just did not start the conversation in the right place.
The investors I see make this transition smoothly are not the ones with the deepest pockets or the most sophisticated portfolios. They are the ones who recognised early that residential and commercial finance are different problems requiring different starting points.
