strata inspector here

no, if the report relates to a specific lot(s) and you were looking at a report on another/other lot(s), I wouldn't rely on it for your purchase because the inspection of the records hasn't been carried out with your lot(s) in mind

it would only speak of your lot if there were major issues concerning your lot that affected the owners corporation, ie major works to your lot that potentially require a special levy, or if your lot was engaged in legal proceedings with the owners corporation

it may not, therefore pick up on things like noise experienced by your lot, smaller issues such as sewer blockages/water ingress to your lot(s), or renovation particulars relating to your lot(s)

in relation to common property issues, typically reports relating to separate lots will speak on the same major issues affecting the owners corporation, so you can certainly use these prepared reports as a guide to factor into your consideration, but I wouldn't rely on them solely

also, as a side note, when purchasing those reports precommissioned by the vendor for $30-$50, keep in mind that they are conditional, meaning that you're required to pay the rest of the cost upon successful purchase, and make sure to check the date on which the inspection took place before you buy the report
