Title Insurance on Tax Sale property

[Kyle Stratton]

I acquired a house by a Sheriff's Deed at a tax sale for unpaid taxes here in Texas.  It was not a homestead, which limits the redemption period to 6 months.  As a homestead in Texas it is 24 month redemption period.

QUESTION:  At what point will a title insurance company issue a title policy?  In other words, to sale the house and to have an owner's title policy, and a mortgagee's title policy (if buyer has mortgage financing) issued would require what kind of elapsed time frame by a title insurance company?

Thoughts?  Answers?
