ENSsquid - that quote is a bit misleading.
Servicemember's Relief Act:
The provisions of this section shall apply to any lease covering premises occupied for dwelling, professional, business, agricultural, or similar purposes in any case in which such lease was executed by or on the behalf of a person who, after the execution of such lease, entered military service...Termination of any such lease providing for monthly payment of rent shall not be effective until thirty days after the first date on which the next rental payment is due... (50 USC A 501)
The federal law only applies to you if you entered service after you started the lease - and even then, it says you are liable for 30 days AFTER the next rent due date (which could be up to 2 mos - the same liability for a lot of apartments for if you break the lease just because you feel like it). So - the act only applies to those of us who are in the same lease we had/have/will have when we commission.
Florida law, however, covers PCS moves -
Any servicemember may terminate his or her rental agreement by providing the landlord with a written notice of termination to be effective on the date stated in the notice that is at least 30 days after the landlord's receipt of the notice if ... the servicemember is required, pursuant to a permanent change of station orders, to move 35 miles or more from the location of the rental premises... (FL 83.682)
A lot of places in Corpus offer a military clause because otherwise they wouldn't ever rent their properties, but they are not required to do so by any federal or state law. The relief act is not the godsend some people make it out to be (the credit card rate change isn't what most people think, either).
Just make sure you read what you sign, is all...and, of course, this is just my interpretation of what I read.
