Open Question: I want to pay off my house, the fastest way possible. Question about a loan. People with experience ONLY!?

Hey everybody, ive lived in my house for 10 years already. techniqually its my moms house but she moved back to germany and left the house under my name. The total balance left on the mortgage is 50,000. Yet im still paying a mortgage of 1400 dollars a month. i havent taken out a second loan on the house and im still trying to figure out why im paying so much.

i want to stop paying so much! Ive contacted mortgage companies and they all want me to refinance the 50 k over a longer period of time like 15 or 30 years. I DONT WANT TO still be paying my house 30 years from now. so what do i do?? What other types of loans are there. I have good credit and was wondering if taken out a personal loan of 50k and paying off the house with that money is a good idea?

Im 23 and im pretty stumped. This is my first house, and really i just want to pay it off so i can rent it out and get the heck out of here.
