Can my SMSF buy a commercial building that has a residential unit attached?

The short answer
It's harder than buying pure commercial. Most lenders that do SMSF loans will say no as soon as there's a residential component, so if you're borrowing inside your super fund, a building with a flat attached knocks out a lot of the options.
It's not impossible. A small number of lenders will look at mixed-use premises, commercial with residential, for an SMSF. But the pool is thin and the terms are tighter, so the purely commercial building is generally the easier path.

The client who asked
I had a client looking at a commercial property with three commercial spaces downstairs, office and business premises, and a little two bedroom flat on top that was residential. On paper it looked like a great SMSF buy: three tenants paying commercial rent, plus a flat.
The problem was the flat. SMSF lending is already a specialist corner of the market, and most of the lenders who play in it want the security to be one thing or the other. A building that's part commercial and part residential doesn't fit neatly into either box, so the common answer is no.
Why lenders get nervous about mixed use
From a lender's perspective, an SMSF loan is already limited recourse: if things go wrong, the bank can generally only go after the property, not the rest of the fund. So they're fussy about the property itself. Mixed-use buildings are harder to value, harder to sell and appeal to a smaller pool of buyers, which makes the bank less comfortable holding them as its only security.
There's also the super side of it. Nobody connected to the fund can live in that flat, and the rules around who can rent what from your SMSF are strict. That's a conversation for your accountant or financial adviser before you get anywhere near a contract, because getting it wrong is a super compliance problem, not just a lending one.
Where a lender does accept mixed use for an SMSF, expect full documentation, a commercial lease in place and a lower maximum loan against the value than you'd get on a home loan.
The no brainer for business owners
If you own a business, a lot of people's no brainer is buying the premises your business trades out of, through your SMSF. Your business pays rent to your super fund instead of to a landlord, and the fund is the one paying down the loan.
Done properly, at market rent with the right structure, it can be a tidy setup. But it's strategy as much as finance, so it's one to run past your accountant. My part is finding the lender that will actually do the loan once the structure is right.
The honest bit: check the lender before you fall for the building
With mixed-use property inside super, the lending is the bottleneck. A building can make complete sense for your fund and still have only one or two lenders willing to touch it, on tighter terms.
So before you sign anything, let me check which lenders will take that specific property, and have your accountant confirm the fund can hold it. Both answers first, then the offer.
