Financing an older home in Decatur, Grant Park, or Marietta
By Alyson Foy, Loan Officer, Edge Home Finance, NMLS #448481 · 8 min read · Updated September 2026
Quick answer
Older homes in intown Atlanta, Decatur, and historic Marietta bring three financing considerations that newer construction does not: appraisal comparables can be thin when houses on the same street differ widely in condition and renovation level, insurance carriers ask more questions about roof, electrical, plumbing, and foundation age, and some properties need a renovation loan rather than a standard purchase loan because condition issues must be addressed to satisfy the lender. None of this makes an older home hard to finance. It means the loan strategy should be chosen before you are under contract with a short inspection window. Subject to credit approval.
Key takeaways
- · Appraisals on mixed-condition streets are less predictable than in uniform subdivisions
- · Insurance quotes should come early, because system age drives cost and eligibility
- · Renovation financing can roll repairs into the mortgage instead of requiring cash
- · Knob-and-tube wiring, older panels, and aging roofs are common conversation points
- · Historic district rules can affect what work is permitted and how long it takes
Why intown appraisals behave differently
In a newer subdivision, the appraiser has five nearly identical homes that sold within a mile in the last few months. In Grant Park or Oakhurst, the house next door might be a fully renovated bungalow and the one behind it largely original, both built the same year.
That spread makes the appraisal less mechanical. Renovation quality, permitted additions, and how square footage was added all carry weight. It is worth knowing whether the finished basement on the listing was permitted, because unpermitted space is treated differently.
Insurance is part of the financing conversation
Homeowners insurance on a century-old house depends heavily on the age of the roof, the electrical panel and wiring, the plumbing supply lines, and the HVAC system. Some carriers decline, others price it in, and the difference can be large enough to move your monthly payment.
Get a quote during your inspection period rather than the week before closing. Insurance is escrowed with your taxes, so a surprise here does not just cost money, it can change your qualifying numbers.
When a renovation loan is the better tool
If a home needs work that a lender requires addressed, or if you simply want to fund improvements without draining savings, renovation financing lets you borrow based on the home's value after the planned work rather than its current condition.
It is a different process: scoped work, contractor documentation, and draws as the work completes. It also takes longer than a standard purchase, so it needs to be part of your offer strategy, not a mid-stream pivot.
The items that come up most on older intown homes
- · Roof age and remaining life, which insurers weigh heavily
- · Original electrical panels or knob-and-tube wiring
- · Galvanized or aging supply plumbing
- · Foundation and crawlspace moisture in older construction
- · Additions and finished basements without permits on record
- · Lead paint and similar disclosures on pre-1978 homes
Historic districts and renovation plans
Parts of Inman Park, Grant Park, Marietta, and other neighborhoods sit in districts with design review. If your plan includes exterior changes, approval timelines can affect a renovation loan's schedule.
This is not a reason to avoid these homes, which are among the most sought-after in the metro. It is a reason to sequence the loan and the plan together from the start.
Common questions
Is it harder to get a mortgage on a 100-year-old home in Atlanta?
Not inherently. Older homes finance routinely. The differences show up in appraisal comparables, insurance eligibility and cost, and whether condition items need to be addressed before closing. Planning for those three items early keeps the process normal.
Will an appraiser require repairs on an older home?
Sometimes. Certain loan types require that health and safety items be addressed, and an appraiser can call out conditions that need repair. When that happens, a renovation loan is often a cleaner path than negotiating repairs in a short window.
Can I finance renovations into my purchase loan?
Yes, renovation loan options exist for exactly that. They base the loan on the home's value after completed work and disburse funds as the work progresses. They require contractor documentation and more time, so factor that into your contract dates.
Does knob-and-tube wiring stop me from buying?
It is more often an insurance question than a mortgage question. Some carriers will not write a policy until it is replaced, and because insurance is required for the loan, that can become a closing condition. Getting an insurance quote early surfaces it in time.
Are unpermitted additions a problem for financing?
They can affect how an appraiser treats square footage and value, which affects your loan amount. It is worth confirming permit history during your inspection period rather than after the appraisal comes back.
