Hi wondering, welcome to the forum.
If owning isn't for you, then I think you should sell. Financially, I don't think it will take you very long to recover, and from then on, you would be on better footing. To make sure, you should run the numbers, or have someone run them for you. This is essentially the typical buy vs. rent question in reverse, and you'll want to consider the whole picture so you make a sound financial decision. You will have to consider, among other things
First time home-buyer credit repayment if you're in the US and you took it. (You'll need to live there for three years if you want to avoid paying this back.)
Capital gains.
Mortgage interest.
Taxes, insurance, upkeep.
Cost of sale, realtor fees.
Opportunity cost - return on investments.
Cost of renting.
Etc.
I hope it works out for you. I'm guessing you would break even in just a few years.
