After my research I no longer wanted a new fancy ready to go home, I was looking for a fixer upper.

You are interested in real estate investing and are looking for resources to develop your knowledge.I work with a lot of doctors and busy, high income earners to help them build real estate portfolios to slow down at work and offset some of their W-2 or business income.Some books to consider are Multi-Family Millions by David Lindahl, Investing in Real Estate with No and Low Money Down by Brandon Turner, and Equity Happens by Robert Helms & Russell Gray.Some You tube channels to follow include Get Rich Education, Ken McElroy, Jason Hartman, and the Real Estate Guys Radio Show.Yes, until you are making attending physician money, I would house hack the house you live in by renting rooms or buying a duplex as a primary residence with low money down.To Your Success!

I did contact the utility company and they suggested to give them a call during business hours and have the utilities disconnected since I no longer own the property.

The loan is interest only and it accrues and is paid when the loan is paid off - there are no monthly interest or principle payments during the life of the loan.

We do all of this with NO TAX RETURNS and no DTI calculations whatsoever.

@Brandt Thompson...assuming you're going conventional financing, and you're truly going to rent the property, just make sure you get a lease agreement signed and if you can't get a deposit, have a 1007/rent schedule done that will back up the lease, and you should be given 75% of the lease to offset the PITIA. 

My guess is the issue is; there is no attorney at the title company and in your state an attorney is required to create a deed.

If it doesn't make sense, and you have no pressing need to get out of your existing loan, then I would wait.
