You should probably do a "pros and cons" list. Are you planning to puchase in Orlando? If so, can you qualify and afford to puchase what you want while covering 2 mortgages? Usually you will need a signed lease agreement and then 75% of the rent you collect will count as income against your mortgage payment.
If it is also a buyers market there, you may lose less by taking the loss in Texas and taking advantage of a buyers market in Florida. My advice would be to talk with your agent ( that you trust) in Fresno, an agent in Florida and a lender that is familiar with the rules in both states or at least in Florida, then make that list and your decision.
