If TX mandates that you must disclose the fact that you have had an inspection,you must. I did recommend that you tell buyers that you had the inspection.
To my knowledge, all states mandate that sellers disclose any known defects or problems. I did recommend that you disclose any and all pieces of information that are known to be a defect or problem.
If TX disclosure form instructs you to attach a copy of the prior inspection report, I would recommend that you find out if that is a request, a customary practice, or a legal requirement. If is is customary and you decline, that could send a signal of concern to a buyer. In an area where such practice was not customary, it may not have the same response. If is mandated by law that you release this report, obviously....comply.
Certainly, all sellers should disclose everything that is a known problem or defect. I recommend that, emphatically.
I stand behind my position in not recommending pre-sale inspections. I had lengthy discussions with several attorneys about this before I established my position and recommendation on this. I know that in some areas of the country. this was recommended as a marketing tool to assure buyers the home was in good condition. There are, obviously, people who think it's a good idea. I don't.
My example of the furnace vent was from real experience, but not from a seller pre-sale inspection. The buyer's inspector asserted the vent was improper. The furnace and venting was 2 yrs old. The sellers contacted the HVAC contractor who did the work, who said the general inspector knew far less about HVAC than he, and that it was proper and safe. Buyers sent in their own HVAC contractor for opinion, who said he concurred with the "recommendation" made by the general inspector. The seller obtained a second opinion from another HVAC contractor that stated that it was proper and safe.
I have seen enough inspection reports to know:
1) Good inspectors can still miss things.
2) Multiple inspection reports on the same property within a short time period will show much overlap, and also many differences.
3) Inspectors have been dead wrong on issues.
4) Two different inspectors can have passionately differing opinions on the same issue.
Comply with the law. Listen to recommendations of your local agent. Understand what is legally required vs. what is customary practice. Absolutely, disclose any facts that you know.
