Need Help on home finance please.?

-I have been living in a manufactured home for over 11 years now and made payments of 550 a month but then i checked the interest rate and its 12% and in the 11 years the principle amount i paid for is $3000+ but now i seen a nice house for $54,000 my question is what would happen if i just went and bought the other house and left the manufactured home?Your salary will have to support two mortgages.

You will be buying a new home, and still paying on an old home.

Plus, you will have to have at least 10% down payment, with closing costs and some insurance upfront
