$48k to go Pay off or Don't pay off the house?

I know there was another thread similar to this but it was from 2006 and I wanted to use my info.

I purchased a house when I was 21, for $116,000 and put down $20,000.

The original loan was fro 7.75% (which was good in 2000) for 15 years. I never refinanced, I was going through a divorce at the time, which prevented me from getting a much lower rate.

I now only owe $48,000 on the loan, due to additional payments over the past 9 years, the loan, with no additional payments is paid off, 02/2014, a year early.

I would like to pay it sooner though. I currently make $63k and have been contributing to a 401k since I was 25. I have 38k in my old company 401k and 20k in my new 401k. I have been contributing 19% of my pay to my traditional 401k, which is about $800 a month.

I am recieving $18,000 in January and also have $10,000 in low interest savings (3.5% (which really isn't that low right now).

I know from doing the math:

7.75% interest rate
25% tax
5.81250% actual cost of loan

But with stocks and things of that nature, I know most are curretly yeilding less than that.

I am thinking about stopping the 19% 401k (traditional) contribution and switching to a just the company match max, and using that extra money to pay off the house, which I could do, in about a year.

I like my house and have no intentions of selling or moving in the next 5 years. My house payment is 890 (P&I) or 1134, with insurance and taxes.

Once the house is paid off, I would go back to the 401k and then use the extra money to invest in other ways.

Is this a smart move? I would love to be 31 or 32 and have my home paid off.

Oh I should add the house is worth about $180,000 to 200,000 now in Phoenix and was worth about $300,000 at the peak of the market. 1900 sqft 2 stories 4 bedrooms

Oh and I have no car payments, no credit card debt, just a student loan, which is at 2.75% interest and still have 6 years to pay on.

That sounds like a decent plan. I would keep the emergency fund, meaning don't use all of that $18k and $10k towards your home. Increasing your monthly payment gives you the option to change your mind, but if you sink all of your remaining, available cash into the home, you would then be house-rich and cash-poor, which could hurt you if an emergency arose.

Are you contributing to a Roth IRA?
