The verdict in three sentences
For a Miami developer selling three new-build programmes, the website is the main sales gallery for remote buyers, who generate around 45 % of leads from Latin America, Europe and other US states. Budget 20,000 to 40,000 USD for a site with a real-time unit grid, 3D tours at roughly 2,500 to 3,500 USD per programme and a connected CRM. A realistic timeline is 8 weeks.
What remote buyers expect before reserving a unit
A buyer in São Paulo, Madrid or Chicago will not fly in before putting down a deposit. They must find online everything a visitor would see in a sales gallery: real availability, floor plans, prices, deposit schedule, legal protections and proof of construction progress.
| Feature | Role for the remote buyer | Indicative 2026 cost |
|---|---|---|
| Real-time unit grid (available, reserved, sold) | Avoid phantom listings, create urgency | 4,000 to 7,000 USD |
| 3D tour per programme | Picture the unit without travelling | 2,500 to 3,500 USD per programme |
| Unit pages with PDF plans and square footage | Compare 1-bed, 2-bed, penthouses | Included in core build |
| Deposit schedule calculator | See payments in USD, EUR or BRL | 2,000 to 3,500 USD |
| Monthly construction photo and video updates | Reassure on progress | 1,000 to 2,000 USD |
| Legal page (escrow, Florida condo disclosures) | Remove fear of fraud | Included in core build |
| Video call booking with a sales agent | Fit São Paulo and Madrid time zones | 1,000 to 1,500 USD |
Typical 2026 quote in USD
For comparison, the same scope for a developer in Dakar costs 2,500,000 to 6,000,000 FCFA (about 3,800 to 9,150 EUR), with 3D tours at 400,000 FCFA per programme.
| Item | Essential | Complete |
|---|---|---|
| Discovery, sitemap, buyer journey | 2,000 USD | 3,500 USD |
| Custom bilingual EN/ES design, mobile first | 4,500 USD | 7,000 USD |
| Next.js development + unit back office | 6,500 USD | 11,500 USD |
| Real-time unit grid | Included (manual updates) | 5,000 USD (synced to CRM) |
| 3D tours (3 programmes) | 3,000 USD (1 programme) | 9,000 USD |
| CRM connection and automated WhatsApp/SMS follow-up | 4,000 USD | 4,000 USD |
| Total | 20,000 USD | 40,000 USD |
| Hosting + maintenance | 350 USD/month | 600 USD/month |
The CRM connection is the highest-return item: every form or WhatsApp click creates a record with its source (country, campaign, programme), and a sales agent follows up within 2 hours, whatever the time zone.

Before the website, the team receives 90 qualified leads per month and converts 1.2 %, about 1 sale a month. With the real-time grid, 3D tours and CRM follow-up within 2 hours, a cautious assumption lifts conversion to 1.8 %, or 1.6 sales a month. Over 12 months, that is about 7 extra sales, or 4,550,000 USD in additional revenue. Even at a 15 % developer margin, the gain exceeds 680,000 USD for 43,200 USD invested.
FAQ
Should unit prices be shown on the site?
Yes, at least a "from" price per unit type. Remote buyers skip listings without prices, and sites that show prices receive leads 2 to 3 times better qualified.
Is a 3D tour worth 2,500 to 3,500 USD per programme?
For a 40-unit programme at 650,000 USD on average, the tour costs about 0.01 % of programme revenue. It also enables remote reservations without a 1,000 USD or more round trip.
How do we manage the unit grid if we also sell through brokers?
The complete version syncs the grid with the CRM: when an agent marks a unit as reserved, the website updates within a minute. The essential version relies on manual updates in the back office.
Can remote buyers pay a deposit online?
A reservation deposit can be collected by card via Stripe, while contract deposits go to an escrow account as Florida law requires. The legal page should explain this clearly.
How long does it take to launch?
Allow 8 weeks for three programmes with 3D tours. An essential version without 3D can launch in 5 weeks if plans and prices are ready.
