Having mates "in the know", ie tradies in related areas, are good for cross referencing the findings of inspections performed by the 3rd parties. To use kremers previous example...if the report states "wiring appears modern." (quite a vague statement for a supposedly comprehensive report imo), yet your mate who is a qualified sparky has examined the property himself is adamant it's the original 50yr old wiring, you would have good reason to be questioning/doubting/challenging the reports validity/other findings, and as to whether or not you should find another inspection company.

Another added bonus of having good mates in trades is they can tell you right away that yes, the wiring is 50yrs old, but they would be able to sort it out for you at $x cost, and you can then account for that extra cost when making your offer. Saving money wherever possible definitely helps take some of that financial pressure & resulting stress off, however, taking the cheapest option every time isn't necessarily the best way..shop around & compare - the more info you can gather & cross reference the easier it will be choosing the best option for you.
