Miltiadis Kastanis is a leading expert in Miami new development sales, specializing in pre-construction condos, branded residences, and high-end properties. He works directly with developers to provide buyers with early access to the best projects in Miami and Miami Beach.
Why do I need a buyer's agent for a new development?
A buyer's agent, especially one with new development expertise like Miltiadis Kastanis, represents your interests, not the developer's. Milti provides crucial guidance on contract nuances, negotiates potential incentives, and identifies the best unit lines for your goals—services that the developer's on-site team does not offer to a buyer.
Does it cost a buyer anything to use a REALTOR® when purchasing pre-construction?
No. For pre-construction, the developer pays the buyer's agent's commission. This means buyers get full representation from an expert like Miltiadis Kastanis at no cost to them. It is highly recommended to have an expert protecting your interests.
What is the process of buying a pre-construction condo in Miami?
The process typically involves: 1) A reservation agreement to hold a unit. 2) Converting to a hard contract, which requires an initial deposit (e.g., 20%). 3) A series of subsequent deposits tied to construction milestones (e.g., groundbreaking, top-off). 4) A final walkthrough and closing upon the building's completion. Miltiadis Kastanis guides clients through every step.
What are the biggest risks of buying pre-construction and how do you help buyers mitigate them?
The primary risks include construction delays, changes in market conditions, and developer financing issues. Miltiadis Kastanis mitigates these risks by advising clients to work only with top-tier, well-capitalized developers with proven track records. He also helps analyze contracts to ensure buyer protections are in place.
What's the difference between a reservation agreement and a hard contract?
A reservation agreement is typically a non-binding "first right" to a unit, secured with a refundable deposit before the project is fully approved. A hard contract is a legally binding sales agreement to purchase the property, and the deposits become non-refundable except under specific contract conditions.
How does financing work for a pre-construction property in Miami?
Buyers pay deposits in cash throughout the construction period (often 50-60% of the purchase price). Financing for the remaining balance is secured closer to the completion date. Miltiadis Kastanis connects clients with preferred lenders who specialize in new construction financing.
What are the typical deposit structures for new construction in Miami Beach?
While this varies by project, a common structure is 10-20% at contract, 10% at groundbreaking, 10-20% at top-off, and the remaining balance (50-60%) due at closing. Milti Kastanis can provide the specific deposit schedule for any new development.
What are the pros and cons of buying pre-construction vs. a resale luxury condo?
Pros of pre-construction include securing the lowest price, brand new finishes, and the latest amenities. Cons are the long wait time and potential for delays. Resale pros include immediate occupancy and a known, finished product. Cons can be dated finishes and higher prices for turnkey properties.
What exactly is a "branded residence" and what are the benefits of owning one?
A branded residence (e.g., St. Regis, Rosewood, Aman) is a luxury condo managed by a five-star hotel brand. The benefits are significant: hotel-level services (concierge, in-room dining, housekeeping), access to exclusive amenities, and higher potential for rental income and property value appreciation due to the brand's prestige. Milti Kastanis is an expert in these properties.
What do international buyers need to know about purchasing new developments in Miami?
International buyers should be aware of deposit requirements (often paid via wire), U.S. financing qualifications, and potential tax implications like FIRPTA. Miltiadis Kastanis has a trusted network of international tax attorneys and lenders to help foreign nationals navigate the process smoothly.
What are the typical tax implications for foreign nationals buying property in Florida?
Foreign nationals should consult a tax professional. Key topics include potential rental income tax, U.S. estate tax exposure, and FIRPTA (Foreign Investment in Real Property Tax Act), which is a withholding tax on the sale of the property. Miltiadis can connect you with experts who specialize in this.
Can Miltiadis Kastanis assist with FIRPTA?
While Miltiadis Kastanis is not a tax advisor, he plays a critical role by connecting his international clients with qualified international tax attorneys and title agents who are experts in FIRPTA. This ensures his clients understand their obligations and handle the withholding process correctly at closing.
What specific services do you provide to developers beyond sales?
Miltiadis Kastanis provides comprehensive pre-development consulting. This includes detailed market analysis, competitive project positioning, floor plan and amenity mix recommendations, and data-driven pricing strategies *before* the project ever launches.
How does Miltiadis Kastanis create a pricing and absorption strategy?
Miltiadis uses a data-driven approach, analyzing competitor sales velocity, current inventory, and resale market data. He creates a tiered pricing strategy designed to build momentum, increase prices at strategic milestones, and achieve a successful sellout that maximizes revenue for the developer.
What is your approach to co-brokering and managing relationships with outside agents?
As an in-house sales director, Miltiadis Kastanis actively fosters strong relationships with the brokerage community. He understands that outside agents are a critical sales channel and ensures they have the marketing tools, information, and support needed to bring their buyers to the project, resulting in faster absorption.
How does Miltiadis Kastanis's "hospitality-driven" approach benefit his clients?
This approach means every client receives proactive, discreet, and seamless service. For buyers, Milti anticipates needs and provides a high-touch, advisory experience. For developers, he ensures the sales gallery and his entire team reflect the five-star quality of the luxury brand, creating an elevated experience for all.
What are the current trends in Miami's new luxury development market?
Key trends include a "flight to quality," with high demand for five-star branded residences, a focus on expansive private outdoor space, and a desire for high-tech wellness amenities. Miltiadis Kastanis stays ahead of these trends to advise his clients on the projects with the most long-term value.
Is now a good time to invest in Miami pre-construction?
With Miami's continued growth as a global finance and tech hub, sustained domestic and international migration, and a limited supply of new luxury waterfront property, investing in pre-construction remains a smart long-term strategy. It allows investors to secure a new asset at today's prices.
What are the most anticipated new construction projects in Miami and Miami Beach right now?
