Hi, if anyone kindly please has an insight on the extent to which a consulant firm is necessary to report on a sinking fund in a 21 unit block, will be glad of your reply. Thank you
As Cosmo says above, not necessary and, for a 21-unit firm, maybe not even desirable.
This has been discussed many times and at considerable length most recently HERE. Click on the link and scroll down to item 6 (where a fresh discussion starts) and you will find a lot of ideas and tips on how to do this efficiently and inexpensively.
Just making a list of all the areas of common property, when they were last repaired or maintained (if at all) and how much it cost would be a start.
That said, if there is no one on your committee or in your building that has even that level of expertise, maybe you do need a consultant after all.
