Credit is imperative when buying a home. Lenders will evaluate your financial situation before lending you money.
If you're looking to try to increase your credit score here are some quick tips:
1. Keep balance of each credit card below 33%.
2. Get a secured loan from a bank and pay it back over a 6 month period.
3. Keep your revolving debt-to-income ratio under 35%.
4. Periodically check your credit report and pay off small balances first.
5. Never close a credit card account permanently.
