How Much House Can I Afford in Acworth? Calculator

Key takeaway

On the default inputs, an $85,000 household income with $400 of monthly debts and $15,000 down affords about $306,000 at a 7.28% rate and a 43% debt-to-income limit. That is below Zillow's typical Acworth home value of $406,860 (August 2026), so change the inputs to your own numbers to see where you land.

How the calculator works

The calculator finds the highest home price whose full monthly payment fits inside a debt-to-income limit. It works in three steps, and every default comes from a published source you can check.

Step 1: your monthly budget from debt-to-income

The CFPB defines debt-to-income (DTI) as all your monthly debt payments divided by your gross monthly income. The calculator turns that around: it takes your yearly income, divides by 12, multiplies by the DTI limit you pick, then subtracts the monthly debts you already pay. What is left is the most the new housing payment can be.

On the defaults: $85,000 / 12 = $7,083.33 a month. 43% of that is $3,045.83. Less $400 of debts leaves $2,645.83 for housing.

Step 2: what goes into the monthly payment

The payment has five parts:

Principal and interest on the loan (price minus your down payment), over 30 years at the rate shown.
Property tax as a percentage of the price, divided by 12.
Homeowners insurance, the yearly premium divided by 12.
Mortgage insurance as a percentage of the loan, divided by 12.
HOA dues, if the home has them (the default is $0).

Step 3: solving for the price

Every part of the payment rises in a straight line with the price, so the calculator solves for the exact price where the payment equals your budget. On the defaults that price is $306,115, shown rounded down to $306,000: principal and interest $1,991.85, property tax $382.64, insurance $137.92 and mortgage insurance $133.43, a total of $2,645.83.

Where the defaults come from

The interest rate is Freddie Mac's 30-year average for the week of October 1, 2026, 7.28%. The 1.50% property tax rate is computed from Cobb County's 2026 millage for a homesteaded home inside Acworth city limits: 40% of the $406,860 typical value is assessed ($162,744), the $10,000 Cobb basic homestead exemption comes off the county general and school levies, and the four levies (county general 8.46, fire 2.97, school 18.70 and City of Acworth 8.95 mills) total $6,088.43, or 1.496% of value. The full method is on the Cobb County property tax guide.

Insurance is $1,655 a year, the Georgia average homeowners premium in NAIC data for 2022, the latest year published. Get a quote on the actual home. Mortgage insurance is 0.55% a year, HUD's annual FHA premium for a 30-year loan at 3.5% down.

What the calculator leaves out

It does not include closing costs, which you pay in cash on top of the down payment (see Georgia closing costs), or FHA's upfront premium of 1.75% of the loan, which is usually added to the loan. Homes inside city limits also carry Acworth's $2 a month street light charge on the tax bill. Homes in unincorporated Acworth pay no city tax, about 1.14% with homestead, and homes in Paulding or Cherokee County use those counties' rates.

How lenders decide what you can borrow

The calculator gives an estimate. A lender sets your real limit after checking your credit, income, debts and savings, and the limits differ by loan type.

Debt-to-income limits by loan type

The three DTI choices in the calculator match published limits. Fannie Mae's Selling Guide caps manually underwritten conventional loans at 36% of stable monthly income, or up to 45% with credit score and reserve requirements met, and allows up to 50% for loans run through its Desktop Underwriter system. HUD's FHA handbook sets 31% for housing and 43% for all debts on manually underwritten loans, rising as high as 40% and 50% with two compensating factors. VA's standard is 41%. Georgia Dream's maximum varies by credit score, so ask a participating lender which limit applies to you.

Credit score

Your score affects which loans you qualify for and how much you must put down. HUD allows FHA loans at 3.5% down with a score of 580 or higher, and requires 10% down for scores from 500 to 579. Georgia Dream's readiness step starts at a 640 score, and its programs are on the Georgia Dream page.

Down payment and mortgage insurance

A smaller down payment means a bigger loan and usually mortgage insurance. FHA charges an upfront premium of 1.75% plus the annual premium. On a conventional loan with less than 20% down, Freddie Mac puts private mortgage insurance at about $30 to $70 a month per $100,000 borrowed, roughly 0.36% to 0.84% a year, so change the mortgage insurance field if you are comparing a conventional loan. The down payment guide covers how much to put down.

Preapproval and the Loan Estimate

A preapproval is a letter saying a lender is generally willing to lend up to an amount, but the CFPB notes it is not a guaranteed loan offer. Once you apply, each lender must send a Loan Estimate within three business days on the same standard form, which makes offers easy to compare. The CFPB also says mortgage credit checks within 45 days count as a single inquiry, so getting quotes from several lenders costs little.

Ways to raise the price you can afford

If your number lands below the homes you want, three levers move it most. Each one can be tested in the calculator.

Pay down a monthly debt

Every $100 of monthly debt you clear adds $100 to the housing budget. On the default rate, tax and insurance, $100 a month carries about $11,700 of home price ($100 / $0.0085504 of payment per dollar of price = $11,695).

Use down payment assistance

Programs such as Georgia Dream and Cobb County homebuyer assistance help with the down payment and closing costs. The calculator only counts cash you enter, so ask a participating lender how assistance changes your numbers.

Look at other home types and ZIP codes

Prices differ across Acworth: Zillow's August 2026 typical value was $378,558 in ZIP 30102 against $432,126 in 30101. Starter homes and townhomes and condos show what each price band buys.

Common questions

How much house can I afford on $70,000 a year?+

About $243,000 on this calculator's defaults. Gross monthly income is $5,833.33; 43% of that is $2,508.33, and less $400 of debts leaves $2,108.33. With $15,000 down at 7.28%, a $243,253 price gives principal and interest of $1,561.73, tax at 1.50% of $304.07, insurance of $137.92 and FHA mortgage insurance of $104.62, totaling $2,108.33. At a 36% limit it falls to about $195,000.

How much income do I need to buy the typical Acworth home?+

About $109,000 a year on the defaults. For Zillow's typical Acworth value of $406,860 (August 2026) with $15,000 down, the loan is $391,860. Principal and interest at 7.28% is $2,681.15, tax $508.58, insurance $137.92 and FHA mortgage insurance $179.60, a $3,507.25 payment. Add $400 of debts and divide $3,907.25 by 43%: $9,086.63 a month, or $109,039 a year.

Why is the property tax default 1.50%?+

It is the first-year tax on a homesteaded home inside Acworth city limits at Cobb County's 2026 millage: $6,088.43 on the $406,860 typical value, or 1.496%. It includes county, fire, school and City of Acworth levies, with the $10,000 Cobb basic homestead exemption. Outside city limits the rate is about 1.14% with homestead. Paulding and Cherokee County addresses use their own rates.

Which debt-to-income limit should I choose?+

Use 43% for a typical estimate. That matches HUD's standard for manually underwritten FHA loans. Choose 36% for a cautious figure, which is Fannie Mae's base limit for manually underwritten conventional loans. Choose 50% to see the upper end, the most Fannie Mae allows through Desktop Underwriter and FHA allows with compensating factors. Your lender decides which limit applies to you.

Does the calculator include Georgia Dream assistance?+

No. The calculator only counts the cash you enter as a down payment, and it does not include closing costs. Georgia Dream assistance has its own amounts, terms and income and price limits, which change each year. Ask a Georgia Dream participating lender how the assistance would change your loan amount and monthly payment.

Is this the same as a preapproval?+

No. The result is an estimate from the numbers you type in, not a loan approval. A preapproval comes from a lender after it reviews your credit, income, debts and assets, and the CFPB notes that even a preapproval is not a guaranteed loan offer. Nothing you enter here is saved or sent.
