@James Piercy -- Trust me, this isn't acceptable in Texas either! In Texas, real estate inspectors are licensed and regulated by TREC just as real estate brokers and agents are. There are standards of practice and specific items that they are required to address and note as deficient or missing. Off the top of my head, I know smoke alarms and screens are two of those (in contrast, they are not required to note the condition of blinds, etc). While I completely agree that it is best for any buyer to physically walk the property prior to closing, there definitely were items that should have been addressed in that inspection during the option period. And from what is sounds like, things that should have been disclosed by the seller.
While there are many reputable, quality rehab/flippers i Austin that "do the job right" -- as we all know, there are also several who lean on more "paint on a pig" approaches. When working with investors, I walk the property as if I'm looking at it as my own personal investment. Be leary of agents who will make sweeping generalizations "this foundation looks ok", "that's not that big of a deal".... those are things they should not be saying, and can be red flags.
Of course, I'm not an attorney and do not give legal advice -- but as a consumer you do have rights. Glad to hear you are talking through that.
Please don't let this experience deter you from Austin -- it really is a GREAT place to live! (And having had moved here from out of state originally, the tax benefits sure aren't bad either!) :)
