First. Make a budget. Keep track of your month expenses, distinguish what are necessary purchases versus nice to have. Try reducing "nice to have" spending and save as much as you can.
Second. Since you plan to buy a house in a year, you don't want to tie your money up in long-term investments. Check out some high interest rate saving accounts, for example www.etrade.com
Third. Get a copy of credit report from each of the 3 credit bureaus and pay to get one of your score, so you know what you are working with. Go through the credit reports and follow their instruction to make corrections when necessary.
Forth. If your credit score is 740+ then you are in good shape. If 680+ not too bad, but you will be paying slightly higher interest rate to borrow for your home. Make sure you continue to pay your bills on time to keep your score up.
Fifth. Make a realistic estimate on how much money you can save by the time you make the purchase. Then use the mortgage calculator on this page http://money.aol.com/calculators/mortgages-home-finance to help you figure out how much money you can afford to borrow. This will help you get a realistic idea on the price range of homes you should be looking.
Remember there are some extra costs for owning a home:
- add about 3% of the price of the home for closing costs.
- if your down payment is less than 20%, you will be required to purchase mortgage insurance
- check out home insurance for your area. be considerate of any special coverage like huricane, flood, earth quake etc.
- you will also be paying property tax each year for your home.
Insurance and property tax could vary quiet a bit on the zoning, county, school district etc. If you are not particular to one area, you may want to compare various neighborhoods for the best situation.
As far as whether you should "acquire" more credit at this time, it is difficult to advice without knowing your current situation. A person's credit should be proportional to his/her income. If a person is making $1500/month and has credit for $50,000, then it is actually a negative for credit score. The general rules about credit:
1. If you have a bunch of charge cards (Master card, Visa, Discover, A/X, department stoes, gas stations etc), try to consolidate and reduce number of open accounts. Try get rid of department stores and gas stations cards and charge all purchases to major credit cards. If you have several major credit cards, then consolidate them into 1-3 accounts.
2. Staying loyal to a credit account will increase your credit score. So if you are deciding which of the Visa or Master Card account to close, keep the one you have the longest.
3. Do not be attempted by 10% store discount and opening more store credit accounts. Each time a company make such inquiry to your credit history is a negative to your credit score.
Best wishes.
