If my mortgage company withdrew acceleration of my loan, do they have to send another notice of intent to accelerate before they foreclose on my Texas home?

Yes. In the Fifth Circuit case of Wilmington Trust, N.A. v. Rob (5th Cir. 2018), the court interpreted Texas law and held that once an acceleration of a mortgage loan is rescinded, the mortgage company must give another demand, i.e. another notice of intent to accelerate to the borrowers, prior to accelerating the loan and posting the property for foreclosure.
