**Inside tip**
While it may be tempting to use credit cards and open new lines of credit to buy things for your future home, don't!
Lenders don't just check your financial situation before you get pre-approved, they may choose to do so throughout the home-buying process and definitely before closing. They will check to see if (or how much) your credit history has changed and if has changed for the worse because higher card balances, new lines of credit, or even a salary decrease could cause you to lose the loan at worst or have to pay a higher interest rate at best.
