This is pretty unusual
I was part of a small complex that self managed. When a lot was for sale, the potential buyer organized a specialist strata inspection company to come to the place where the records were kept and go through them.
They brought their own scanners and did the work themselves
I woild hesitate to dotheir bidding. Let them go through whatever theywant to see and sort it out themselves.
Being self managed, I would be certain that your books and records are not in a form that the strata management companies use. Thats ok as long as your strata holds the right records and you are able to manage from them.
By you doing the runaround you spend a lot of time. The strata inspectors have never spent more than an hour looking through my books.
