IS A HOME INSPECTION REQUIRED?
No, not by law and not by your lender. A home inspection is a feel good moment for the buyer created by the real estate industry. Home inspectors are licensed by the Texas Real Estate Commission. Look carefully at the Texas Home Inspection requirements on the standard report. A home inspection is basically an inventory of variouses items in a home. If you had the list, you could probably find everything as well.
The home inspector makes a visual inspection only. To the home inspection industry, this means that unless damage is so obvious you yourself could see it, they are not going to provide any form of opinion about a property.
For example, a home inspector might see cavitation and pinholes in a door frame. He can report that as damage. He can suggest you have further inspections of this doorframe by a licensed pest control opertator. But he is not required under the TREC rules to opine what caused the damage or whether there really is damage behind the walls.
So is a home inspection required? No, not by law and not by the lender. Most lenders require a termite inspection or wood destroying insect report. But virtually no one requires a home inspection.
That said, jurors and regular people consider a home inspection a matter or due diligence by the buyer. So while not required by law or by your lender, a home inspection is required by the court of public opinion if the problem you have with a house is something an inspector could have found.
