Lying on your resume is a very bad idea. It's the number one reason to get disqualified.
90 Percent of Interviewers Would Disqualify a Job Candidate for This 1 Reason
I don't see how representing yourself as unemployed could possible be a benefit. That would imply you either quit in a rage without a backup plan or were fired; and it would remove your ability to negotiate a higher salary. When human resources goes to verify employment history, any mismatch between what is on the application package and what your previous employer states would likely lead to immediate disqualification. If it isn't discovered until after you're hired, it would lead to immediate termination. It is far better to accurately represent yourself as currently employed.
The address is also very important. What happens when human resources sends you to LabCorp in one city based off your address for a urine drug screen and you are a hundred miles away at work? The fake address would be apparent and create problems when they do background checks, run a credit report, and look at your license. In Pennsylvania, you have to report address changes within 10 days to the board of pharmacy.
Here's what I would do: Put your current Maryland address on your application. Remove your address from the resume (it's not relevant to work experience anyway). In your cover letter, make it clear you are available for an onsite interview. Describe your move as if it is already an inevitable fact, something like: "I am available for an onsite interview throughout January. In preparation for relocating back home to Philadelphia to be with my family in the middle of February, I have obtained a Pennsylvania pharmacist license." This actually makes you a strong candidate, since you are moving for a great reason (to be with family), instead of some reason like you don't like your boss, you're not paid enough, or some other reason that reflects poorly on your or your previous employer.
As a non-local candidate, you will be at a disadvantage. But I have gotten plenty of prescreens and even two interviews from 2000-3000 miles away. The first conversation usually is designed to find out whether I'm currently employed, why I am not employed or why I am leaving my current job, where I am physically located, why I want to move, and what ties I have to the local area (i.e. am I a flight risk?). Just have confident answers about your strong ties to Philadelphia and how you love your current job, but for family reasons you have to move, but that it's also no big deal to move, because you need to be in Philadelphia. If you own a home in Maryland, have an explanation ready that makes it clear that your move to Philadelphia is not dependent on selling your Maryland place. "I already sold my home and am currently living in a month-to-month rental -- that's how committed I am to moving to Philadelphia."
If there's no dedicated cover letter space, I create one document that contains both my cover letter and resume and upload it in the space for the resume.
