It's a block of 5 on top of commercial buildings.
Mixed use buildings like this often have two strata committees, one for the residential part and one for the commercial part. Inspect both sets of books and minutes.
Be very careful to determine if the commercial part has somehow managed to get the residential part to pay many of their expenses. E.g. garbage disposal, water, and energy use.
Make sure that common property really is available for use. Often the commercial tenants will just take over part of it for their business use. And then they exclude the residents, but insist they keep paying for cleaning.
Is there appropriate security between the commercial and residential areas? Make sure the commercial areas do not have access, for any reason, to the residences. It's not uncommon for their customers to just walk through residential areas. This includes residential car parks.
Check car parking, again commercial tenants will insist that all of the visitor parking be used for their customers.
Check strata management agreements, again lots of dodgy stuff happens.
Too often their focus is looking after the commercial tenants to the detriment of the residents.
It can be very risky buying into a mixed use building so take a lot of care and get the appropriate professional to look over it for you. And then when you move in, be active on the committee. You'll see problems before they become too big.
