Can ED accepted student back out if the College refuses financial aid?

Question on In state and Out of State
I am a resident of TX for the last 10 years.
Now, if my daughter does Pre-Med in a college outside TX, then will she be considered as In State when applying for Medical School (based off my residence status)
OR
If she does Pre-Med outside TX, then is she considered Out of State for Medical School if wanting to get admitted in a Texas Medical school?
The above can also sway her decision towards staying in state. UT Austin is no doubt an awesome school and hopefully this can be the thing that finally convinces her.
