The verdict in three sentences
A family-run luxury real estate agency in Nashville can expect USD 10,000 to 40,000 for a redesign with a local agency in 2026, versus a fixed Growth USD 4,900 or Premium USD 8,900 with Kolonell, IDX feed on quote. The moment that goes wrong is rarely the design: it is the DNS cutover, when email stops arriving, contact forms send to nobody and a buyer's enquiry on a Green Hills home sits unread for two days. Write a cutover plan covering MX records, SPF, DKIM and DMARC, and enquiry routing, test it, and the switch takes minutes.
Why is the cutover the riskiest day of a real estate redesign?
Nashville's high-end market spans Belle Meade, Green Hills, Brentwood and Franklin, with buyers that include people moving for the music industry and corporate relocations. These clients often enquire once, from a phone, and expect an answer the same day. During a redesign, three things can break silently:
- Email: if the domain's DNS moves to a new host and the MX records are not copied, the agency's mailboxes stop receiving. Nobody notices until a client calls.
- Deliverability: the new site sends form notifications from a new server. Without SPF, DKIM and DMARC aligned, those notifications land in spam or bounce.
- Routing: sales enquiries, rental requests from tenants and owner requests end up in one inbox, or in the inbox of an agent who left.
None of this is visible in a design review, which is why it needs its own checklist.
What does the cutover checklist look like?
| Item | 7 to 1 days before | Switch day | 1 to 14 days after |
|---|---|---|---|
| DNS TTL | Lower to 300 seconds 48 hours ahead | Change A or CNAME records only | Raise TTL again |
| MX records | Copy and verify every MX entry | Leave untouched | Send test emails from 2 outside accounts |
| SPF, DKIM, DMARC | Add the new sending service to SPF, publish DKIM | Check alignment with a mail tester | Read DMARC reports weekly |
| Contact forms | Map each form to a named inbox plus a backup | Submit 1 test per form | Daily test for the first 5 days |
| Sales vs rentals routing | Separate addresses for buyers, tenants, owners | Confirm each route with a real message | Review unanswered enquiries |
| Redirects | 301 map for listings and neighborhood pages | Deploy with the site | Check the 404 report |
| Rollback | Keep the old site reachable on a backup address | Ready if a blocker appears | Retire after 14 days |
Planned this way, the visible interruption is usually measured in minutes, on a weekday morning Central Time, never on a Friday evening.
How much should a Nashville agency budget, over three years?
Ranges are a 2026 ballpark from typical agency quotes and public agency rate pages in Middle Tennessee. Market maintenance figures are an assumption, not a Kolonell price.
| Cost line | Nashville agency | Freelancer | Kolonell |
|---|---|---|---|
| Redesign, year 1 | USD 10,000 to 40,000 | USD 3,500 to 10,000 | Starter USD 2,900, Growth USD 4,900, Premium USD 8,900 |
| Cutover and email audit | Often billed hourly | Rarely done | Included in the plan |
| MLS/IDX feed or property CRM | Separate line | Plugin | On quote |
| Photography, video, floor plans | Third-party | Third-party | Third-party (local photographer) |
| Support | Retainer | Hourly | 3 months included |
| Maintenance, years 2 and 3 (market assumption) | USD 150 to 500 per month | USD 50 to 200 per month | On quote |
Tiers and inclusions are listed on the international websites page.
What is the realistic timeline, and what else can go wrong?
Kolonell delivers in 3 to 4 weeks once content is ready: week 1 URL inventory, DNS and email audit, sitemap; week 2 design and copy; week 3 build, listing and neighborhood migration, IDX if quoted; week 4 redirects, accessibility checks, compliance review and cutover.
Other risks to plan for:
- SEO: neighborhood guides for Belle Meade or Franklin that rank need a 1-to-1 301; sold listings go to a sold archive or the area page, never a 404.
- Forms and data: collect name, contact, property reference and an optional budget. No ID or bank documents in open forms; buyer anti-money-laundering checks stay in your agency's process.
- Advertising and licensing: the Fair Housing Act applies to listing and neighborhood wording; your firm is licensed under the Tennessee Real Estate Commission and IDX display rules come from your MLS. Commission and buyer agreement wording changed after the 2024 NAR settlement, so your principal broker signs it off.
- Accessibility and email marketing: ADA Title III website suits are frequent, so target WCAG 2.1 or 2.2 AA; newsletters follow CAN-SPAM. This is not legal advice.
Questions to ask any provider: Who holds the DNS access on switch day? Will you copy our MX records before changing anything? Which address sends form notifications? What is the rollback plan?

If your DNS, email and website are tangled with an IT provider who only works on site, or you want one Nashville vendor to handle photography, print and signage too, a local agency is simpler. If the brand is in place and the job is a cleaner site with a safe switch, a remote studio with a project manager in Central Time hours works well.
Mini case study
Illustrative example: Whitfield Hollow Realty (a fictional agency) is run by a mother and her two sons in Green Hills. They sell high-end homes and manage 25 rentals. They use 6 mailboxes and need 3 form routes: buyers, tenants, owners.
- Local agency quote: USD 24,000 plus USD 1,200 for launch-day support, so USD 25,200.
- Kolonell Growth: USD 4,900, cutover plan, email audit and routing tests included.
- Local photographer (third-party): USD 1,000 in both cases. IDX feed on quote in both cases.
Known spend: 25,200 + 1,000 = USD 26,200 versus 4,900 + 1,000 = USD 5,900, a gap of USD 20,300. The test plan: 3 routes x 5 days = 15 daily test enquiries after launch.
FAQ
Will our email stop working during the redesign?
Not if MX records are copied and verified before the DNS change. We send tests from 2 outside accounts on switch day.
How long is the site offline?
Usually minutes, thanks to a TTL lowered to 300 seconds 48 hours ahead. A rollback stays ready for 14 days.
Why do form notifications land in spam?
Usually SPF, DKIM or DMARC do not cover the new sending service. Fixing it takes 1 to 2 hours if planned.
Is the IDX feed included?
No, the MLS/IDX feed is always on quote. Growth at USD 4,900 covers design, copy, migration and the cutover plan.
What happens after the 3 months of support?
Kolonell maintenance is then on quote. Many agencies keep a light plan for updates and monitoring.
