This answer is short and to the point. You need Texas Home Insurance for the following reasons.

1) If you have a mortgage, it is overwhelmingly likely that you are required to have texas home owners insurance. Mortgage companies do check from time to time and will put a "forced placed" policy into effect if you do not have a valid policy. Forced Placed insurance is billed back to the homeowner by the mortgage company. It is usually very expensive when compared to normal home insurance policies.  Not having a policy could cost you a lot of extra money even without a catastrophic event.

2) A home is probably the most valuable investment you will make. Protecting your largest asset from catastrophic loss should be a priority. Even if you own your home outright and do not have a mortgage, protecting yourself from catastrophic loss is a no-brainer.
