Walkability, transit, distance to beach or bay, and traffic patterns vary block by block and are best evaluated in person; visit at both a weekday rush hour and a weekend afternoon before writing an offer.

We will gladly provide objective data on request: distance to nearest grocery, hospital, marina, public school, and major roadway.

What are the property taxes and any homestead implications?

Miami-Dade County real-estate taxes are administered by the Miami-Dade Property Appraiser (current assessment + tax-bill data at https://www.miamidade.gov/pa/property_search.asp). A new buyer's tax bill resets based on the sale price and the buyer's own exemption status; the first full tax bill after purchase is often meaningfully higher than the seller's prior bill. Florida's Homestead Exemption reduces the taxable value for a primary residence — eligibility requirements and filing windows are published at https://www.miamidade.gov/pa/exemptions_homestead.asp. The statewide Florida Department of Revenue property-tax reference is at https://floridarevenue.com/property/.

Is it in a flood zone, and what does that mean for insurance?

Authoritative flood-zone designation for any U.S. address is published by FEMA on the National Flood Hazard Layer at https://msc.fema.gov/portal/home. Coastal South Florida includes properties in multiple flood-risk zones (AE, V, VE, X). Lenders typically require flood insurance in high-risk zones. The FEMA Risk Rating 2.0 methodology (premiums based on elevation, construction type, claims history, distance to water) is documented at https://www.fema.gov/flood-insurance/risk-rating. Florida-specific flood-insurance program data is at https://floridarevenue.com/.

How do you determine the list price?

We analyze recent comparable sales in Key Biscayne — similar properties in size, condition, and location that sold within the last three to six months. This Comparative Market Analysis (CMA) helps ensure 8,500,000 reflects current market value. For a personalized CMA on a specific property or to discuss listing strategy, contact us directly.

How long does it typically take to close on this property?

Most Florida real estate transactions close in 30–45 days from accepted offer, assuming timely financing, inspections, and HOA or condominium questionnaire responses. Condominium sales may take longer if SB-4D structural reports or association approvals are needed. We manage the timeline closely to avoid delays. Contact us for a detailed closing checklist tailored to 238 Buttonwood Dr, Key Biscayne FL 33149.

What financing step do you recommend before touring?

Get pre-approved by a licensed lender before making an offer. A pre-approval letter shows sellers you are a serious buyer and can close. In Florida's competitive market, it is often a practical requirement. We work with trusted local lenders who understand Miami-Dade specifics like flood-zone implications and condominium-warrantability requirements. Call us for lender referrals.
