You have an attorney, or should if in probate, but probate attorneys are not always versed in Real Estate. But you really did not ask us for Legal advise you asked for the answer to a fact of Real Estate in Texas.
The answer is Yes and No.
If there is still a first mortgage the HOA can not foreclose. If there is no first mortgage the HOA can foreclose.
When there is a first in Texas they are the only ones that can foreclose but once that is paid the others can play first come.
I you or the deceased still owes on the property the HOA can place a lien on the property so that clear title does not transfer until they are paid.
This is a legal question, and as a Realtor, I am not suppose to give legal advice. I can give you an opinion and that is ALL it would be.....seek legal advice.
