I am a Licensed Mortgage Loan Originator in Texas, and have been originating loans for over 12 years. (I'm not licensed in GA, so this is NOT a solicitation for your business, only my professional opinion).
Your mortgage professional will pull your credit and count all of your monthly payment obligations (credit cards, car and student loans, etc), plus the new mortgage payment (Principal, Interest, Taxes, Insurance, and if applicable, Mortgage Insurance and Homeowner's Association dues) against your gross income to establish your debt to income ratio. In our current lending environment, it is common to not allow in excess of 41%. The balances are somewhat less important than the monthly payments, but the balances are indicative of overall strength of your file.
You will need a down payment and reserves in savings. Your down payment can range from 3.5% on up, depending on the type of loan you are applying for. It can also be a gift, under certain programs, but you will need reserves in savings.
I would highly encourage you to leave your unsecured cards OPEN, even if you cut them up. If you close the card, you are reducing the longevity of your credit file. Also, closed cards with balances can fire negatively with the Automated Underwriting System.
Now is the perfect time for you to select your mortgage professional and begin the pre-qualification process. They will begin with pulling your credit and analyzing it in relation to your income and assets. They will also tell you, based on the aforementioned debt to income ratio, what your max purchase price will be. Like I said, the balances are less important, but the overall debt to income ratio will be affected, and likewise the amount of house you can qualify for, because the higher the balances, the higher the monthly payments. Keep in mind, they will pull your credit once now and once when you are nearing putting in your offer on a property and this does NOT lower your credit score. It is the act of multiple lenders in a short period of time pulling credit that can negatively affect your scores.
I wish I could offer a referral to someone in Georgia, but I don't know anyone. Our industry has had a world of change in the past years, and is drastically changing again, this year. I would suggest interviewing your Originator and ask about their time in the business, are they licensed under the new laws (vs. operating under a provisional license), whether they handle predominately purchase or refinance business, and I always encourage people to get a personal referral from a trusted source.
I hope this helps! Best of luck to you. Message me if you have additional questions.
