These are all important questions that will affect a decision to rent. As mentioned already, it is negative at this point. If you bought it a long time ago, you probably won't have a very high basis that would help with depreciation for tax benefits to soften that burden. Depending on your income, you may not be able to take advantage of depreciation and losses.
It isn't very hard to rent out a condo and you have a central location for commuting (I've sold several units in Vista del Lago over the years). There is more to renting than just an ad on Craigslist. There are disclosures, detailed credit reports and tenant screening, maintenance, collecting the rent, etc. It is just a commitment to a little extra work if you're up to it. Or you could sell it and commit your resources to a potentially better home to move into. I can't tell from your question if that is in the equation or not.
The Feds lowered interest rates (again) today, so you may consider a refinance to a lower rate to see if it might lower your monthly payment on your mortgage.
