Jim, Nolan,
That was my answer too, hence the

.
Why not market "Maintenance Inspections" and semi-intentionally make sure that no one tells you the home is 'for sale' and they are having you do a 'pre-listing inspection' ...

(of course, you would not want to see a 'For Sale' sign there ... )
That way, you are not limited in what you inspect nor in how you report it. You are dealing 'with the owner' of a property, which to your knowledge 'is not for sale', and thus outside the grasp of controlling influences like TREC.
Yes, I know, the same problems of 'disclosure' for the seller would plague this 'Maintenance Inspection', but you would be outside the grasp of TREC and instead of making sure you cross your 't' and dot you 'i' to fulfill TREC's requirements, you could spend your time on actually inspecting and reporting on what you think is most important to your client. No hanky-panky to please TREC of the real estate agent (to your knowledge, they are not 'involved' yet).
I know you saw this, or something like this coming (from my questioning), but it might work as another avenue for business?
Heck, would you even need to be a TREC licensed 'home inspector' for those inspections which are done outside the scope of TREC?
