THDA vs. Georgia Dream: Which State Bond Program Wins for Border Buyers?

For most first-time buyers on the Tennessee–Georgia border, THDA Great Choice is the stronger pick: it pairs a 30-year fixed loan with up to $10,000 in forgivable down payment assistance that clears after 10 years, plus up to $25,000 on newly built homes. Georgia Dream only wins when you need a higher price ceiling — it allows up to $625,000 versus Tennessee's county-based caps — or when your household income fits its tighter limits. Your choice is settled by where the house sits, so shop the neighborhood first.

Quick answers

These are the core facts that drive the decision.

What each program offers

THDA Great Choice is Tennessee's flagship 30-year, fixed-rate mortgage for moderate-income buyers, run by the Tennessee Housing Development Agency. Qualifying borrowers need a minimum credit score of 640 for everyone on the loan, and the purchase price and household income limits vary by county (THDA). Down payment assistance rides on a second loan called Great Choice Plus: up to $6,000 or $10,000 as a forgivable second mortgage at 0% interest, forgiven at the end of a 10-year term, or up to 5% of the sales price capped at $15,000 as a fully amortizing second loan (THDA).

Georgia Dream is the Georgia Housing and Finance Authority's (GHFA) homeownership program within the Department of Community Affairs (DCA). The base program is first-time buyers only, with a maximum home sales price of up to $625,000 and income caps of $137,555 for one or two persons and $158,188 for three or more (DCA). Down payment assistance options are available, and the current rate on the Georgia Dream First Mortgage is 6.000% on a 30-year fixed (DCA rates).

Key takeaways

• THDA Great Choice: 30-year fixed, 640 minimum credit score, income and price limits set by county, with up to $10,000 in forgivable down payment assistance after 10 years.

• Georgia Dream: first-time buyers only, up to $625,000 sales price, income capped at $137,555 (1–2 people) or $158,188 (3+), with down payment assistance options.

• Both require homebuyer education and owner-occupancy; your state of purchase — not your state of residence — decides which program you can use.

• Border buyers can only use the program on the side where the house sits, so shop the home first, then match the program.

Decision matrix: THDA Great Choice vs. Georgia Dream

This table compares the two programs on the questions first-time buyers actually ask — not on vendor feature names.

The affordability gap these programs are built to close

Home prices have climbed across the region. THDA's own economists note that smaller Tennessee markets, including Chattanooga, have faced housing affordability challenges that were almost unheard of two decades ago (THDA). When families could once choose a neighborhood by school zone or walkability, the question has shifted to the more basic one of whether they can afford to live there at all.

State bond programs are the bridge across that gap. Both THDA and Georgia Dream sell tax-exempt mortgage revenue bonds to fund below-market-rate home loans, then pair them with down payment assistance so a buyer who saved up a down payment but not closing costs — or neither — can still close. The catch is that each program's money is tied to the state where the house sits, not where you currently rent or work.

THDA Great Choice: Tennessee's moderate-income workhorse

The Tennessee Housing Development Agency's Great Choice is a 30-year, fixed-rate mortgage designed for middle- and moderate-income Tennesseans (THDA). Every person on the loan needs a minimum credit score of 640, and both your household income and the home's purchase price must fall within limits that vary by county. Because most Great Choice loans are insured by FHA or USDA-RD, you can borrow up to 96.5% of the home's price — meaning a down payment as low as 3.5%.

The down payment assistance, and its string

Great Choice Plus is the second-loan program that covers your down payment and closing costs. There are two ways to take it. The deferred option gives you up to $6,000 or $10,000 as a forgivable second mortgage at 0% interest, and the loan is forgiven at the end of a 10-year term — but if you sell or refinance before year 10, the balance comes due in full. The amortizing option is up to 5% of the sales price capped at $15,000, with a 30-year term and an interest rate matching your first mortgage (THDA).

For newly built homes, THDA pushes the assistance further: up to $25,000 in down payment and closing cost help at 0% interest on a 15-year second mortgage, with a statewide purchase limit of $500,000 (THDA). That is the strongest raw assistance figure either state offers — but it is reserved for new construction.

Mini-verdict: THDA is the better fit when your income fits a moderate band, you can stay put 10 years to clear the forgivable second loan, and you want the lowest possible upfront cash out of pocket.

Georgia Dream: higher price ceiling, tighter income cap

Georgia Dream is the homeownership arm of the Georgia Department of Community Affairs, operating through the Georgia Housing and Finance Authority (GHFA). The base Georgia Dream loan is first-time buyers only, allows a maximum home sales price of up to $625,000, and caps household income at $137,555 for one or two persons and $158,188 for three or more (DCA). Down payment assistance options are available on the first mortgage. The current rate on the Georgia Dream First Mortgage is 6.000% on a 30-year fixed (DCA rates).

Georgia also defines first-time status by a three-year window: a borrower qualifies if they have had no ownership interest in a principal residence within the last three years, unless the property sits in a Targeted Area (DCA). That matters for border buyers who previously owned a home — you may still be treated as a first-time buyer in Georgia even if Tennessee would count you as a repeat buyer.

Where Georgia Dream stretches further

The base program's $625,000 price ceiling clears the county-based THDA caps in most Chattanooga-adjacent Georgia counties, which helps buyers aiming at a newer or larger first home. Georgia also layers on higher-tier products for repeat buyers — Peach Plus raises the price ceiling to $725,000 with income caps of $206,333 (1–2 people) or $237,282 (3+), and Peach Advantage reaches up to 150% of the area median income (DCA). The tradeoff is that these higher rungs generally carry higher rates than the base Georgia Dream loan.

Mini-verdict: Georgia Dream wins for buyers whose household income fits its stricter caps but who need the larger $625,000 price ceiling — and for repeat buyers who lost first-time status on the Tennessee side.

The border advantage: shop the house, then the program

Here is the part that makes Chattanooga unique. On this stretch of the line, you can buy in a Tennessee county and use THDA, or cross into a north Georgia county and use Georgia Dream — and the programs cannot be mixed. Your eligibility is decided by where the house sits, not where you live or work, so the smart sequence is to pick your target neighborhoods first and then compare each program's limits for that specific county.

Mini-verdict: Treat the two programs as the full menu, price both against the specific home you want, and let whichever state the house is in make the final call.

Choose THDA if… / Choose Georgia Dream if…

Pick THDA Great Choice if your household income and target purchase price fit Tennessee's county limits, you can stay in the home for 10 years to clear the forgivable second mortgage, you want up to $25,000 in assistance on a newly built home, or you qualify for the Heroes rate discount as a veteran, teacher, firefighter, or EMT.

Pick Georgia Dream if your household income fits its caps but you need the larger $625,000 price ceiling, you have first-time status under Georgia's three-year ownership window, or you are a repeat buyer who can step up to Peach Plus or Peach Advantage on the Georgia side.

A note from Tony Naples, a mortgage professional in Chattanooga: state programs are powerful, but the rates and limits change with each bond issuance, and the exact income and price numbers for your county matter more than any national average. Run your specific numbers against the current county chart before you commit, and pair the state assistance with a homebuyer education course, which both states require for down payment assistance.
