My desire would be to tender a contract to purchase the property, pay off their loan while ensuring the owner receives fair compensation and I receive the house.

@William Coet it’s a different business model altogether.I love highly desirable areas that attract highly skilled high income college educated workforces.They tend to be more liberal and therefore the landlord tenant laws.The percent of their income that goes to rent is typically much less than 20% so a rental increase of 5-10% is nothing to them.They are typically lower cap rate areas and therefore every dollar of net operating income that is earned is explosive to the underlying asset value.

If you have an opportunity presented, and your equity can earn more money in that deal, then I would roll it over.

What is the best and most cost efficient program to earn a real estate license in Texas?

Good STR areas are often times desirable places to live as well, so prices tend to be higher in my experience.
