Consider a person with a credit score of 720 and another with a score of 590 buying the same house in Duluth. The outcomes will differ. With a score of 720, they are likely to qualify for a conventional loan with a 5% down payment and a relatively low interest rate. With a score of 590, they will need to switch to an FHA loan and prepare a 10% down payment.

The median sale price in Duluth, based on Redfin's data from the last three months, is $489,000. This is a 5.1% decrease compared to the previous year. A 5% down payment would require $24,450, while a 10% down payment would need $48,900. This means that just one credit score can nearly double the initial cash burden.

So, which is more advantageous, FHA or conventional? For those with a credit score of 580 or higher, FHA requires a 3.5% down payment, while those with scores between 500 and 579 need a 10% down payment. Conventional loans can start at 3% for first-time homebuyers or those with an income at or below 80% of the area median income. If the down payment is less than 20%, both options will incur PMI or mortgage insurance premiums.

What about interest rates? According to Freddie Mac's PMMS, the average 30-year fixed rate is 6.6%. If your credit score is low, you may be offered a higher rate than this average. For a loan amount of $464,550 (based on a 5% down payment) at 6.6%, the monthly principal and interest payment would be around $2,965.

How much should you consider DTI? Generally, the total debt repayment should not exceed 43% of your income to widen your approval chances. Getting pre-approved allows you to check this number in advance.

What about property taxes? The average effective tax rate in Georgia is around 0.92%, and rates can vary within Gwinnett County. For a $489,000 home, the annual property tax could be approximately $4,500. You should verify the exact rate with the county tax office.

Duluth is a preferred area for Korean families due to its school districts. While GreatSchools ratings are helpful, school district boundaries change frequently. You should verify the assigned school before purchasing.

How much are closing costs? Typically, they range from 2% to 5% of the loan amount. For a loan of $464,550, you would need between $9,300 and $23,000 in addition to the down payment. If your credit score is low, you should also check your cash reserves to cover these costs.

How can you improve your credit score? The basics include reducing existing credit card debt and not missing payment dates. Opening new cards in a hurry can actually lower your score. It's safer to avoid large expenses or new loans starting six months before applying for a mortgage.

The interest rate differences by credit score are more significant than you might think. Recent data shows that for scores above 780, the average 30-year fixed rate is 6.59%, while it is 6.66% for the 760s, 6.75% for the 740s, and 6.91% for the 700s, with rates increasing slightly as scores decrease. According to myFICO's loan savings calculator, raising a score from the 620s to above 760 on a $300,000 loan could reduce monthly payments by $156 and save $56,103 in total interest over 30 years. In the Duluth market, where loan amounts are significant, this difference translates directly into total cost disparities.

You should also decide on the type of interest rate in advance. A 30-year fixed rate keeps the same rate throughout the repayment period, making budgeting easier. In contrast, a variable rate product like a 5/1 ARM applies a fixed rate for the first five years and then adjusts annually based on market rates. While the initial rate may be lower than fixed rates, there is a risk of sudden increases in monthly payments if rates rise after five years. If you don't plan to move or refinance within five years, a fixed rate is generally more stable.

Before applying for pre-approval, it's wise to gather your documents. You will typically need identification, recent pay stubs from the last one or two months, W-2s or tax returns from the last two years, and bank statements from the last 2-3 months. If you are self-employed, you may also need profit and loss statements or 1099 income verification. Having your documents organized in advance can help prevent delays in approval when making an offer, reducing the risk of missing out on your desired property.

If the down payment is a concern, consider the Georgia Dream program. With a credit score of 640 or higher and a minimum of $1,000 out of pocket, you can receive interest-free assistance of up to $10,000 to $12,500. This article is not investment or legal advice.
