An advertised HOA estimate is only the starting point for ownership underwriting at St. Regis® Residences Sunny Isles. A disciplined review separates insurance, staffing, utilities, reserves, and tower-specific allocations before translating budget pressure into a residence’s monthly cost.
At St. Regis® Residences Sunny Isles, the ownership question extends beyond the purchase price. For a buyer evaluating a long-term oceanfront residence, the more revealing exercise is to understand what sustains the experience: insurance, staffing, utilities, and capital reserves.
The development at 18801 Collins Avenue in Sunny Isles Beach is planned as two oceanfront residential towers, each approximately 62 stories and 750 feet tall. Advertised delivery targets are Q4 2028 for the South Tower and Q4 2029 for the North Tower. These are expectations, not guaranteed completion dates.
That phased schedule makes expense allocation especially important. The figure to underwrite is not simply the opening assessment, but the cost of supporting the property as both towers become operational. A polished ownership experience deserves an equally clear financial foundation.
The advertised HOA estimate of $1.70 per interior square foot per month is a preliminary reference-not an adopted association budget or a promise of future charges.
Applied directly to interior area, that estimate produces:
| Interior area | Illustrative monthly assessment | | --- | ---: | | 2,000 Square feet | $3,400 | | 3,300 Square feet | $5,610 | | 4,500 Square feet | $7,650 |
These figures exclude increases or special assessments. They are a screening tool, not a substitute for the first-year assessment package and governing documents.
The distinction matters: a square-foot marketing estimate does not establish how every association expense will legally be allocated. Before treating any figure as an ownership commitment, confirm what it includes, which budget period it represents, and whether reserves are included in the quoted amount.
A two-tower development requires a clear map of financial responsibility. Ask counsel to trace tower-specific expenses, shared amenities, and any separate association or shared-facility obligations through the governing documents. Do not presume that all costs fall within one common budget.
The essential questions concern allocation and timing. Which expenses belong exclusively to each tower? How are shared costs divided? What assumptions apply while one tower is operating and the other has not yet opened? Is any initial assessment supported by a developer subsidy or assessment guarantee, and when does that support end?
For buyers also considering Bentley Residences Sunny Isles, this is the appropriate comparison framework: evaluate each property's documented obligations rather than assuming similarly positioned residences share the same expense structure.
Reconcile the opening estimate with a full-operation budget. If phased occupancy or temporary support affects the initial figure, model the removal of that support separately from expense inflation.
The most useful stress test isolates costs that can move independently. The following ranges are illustrative scenarios, not forecasts for this property.
Insurance: test increases of 20% to 40%.
Apply the increase to the relevant annual insurance expense, not the entire assessment. Review coverage assumptions, insured values, deductibles, exclusions, and renewal timing. A higher deductible warrants a separate liquidity discussion; a premium-only sensitivity does not capture that exposure.
Florida condominium associations must maintain adequate property insurance for the condominium property they are legally required to insure. They must also maintain adequate insurance or fidelity bonding for people who control or disburse association funds. Neither requirement establishes the scope of an individual owner's coverage.
Payroll: test increases of 10% to 20%.
Request the staffing plan and distinguish wages from benefits, overtime, management charges, and contracted services. Confirm which costs are included in the payroll line so the model neither overlooks them nor counts them twice. The underwriting question is whether the proposed budget supports the intended service level without relying on temporary staffing assumptions.
Utilities: test increases of 10% to 25%.
Review both rate and consumption assumptions. Separate common-area costs from individually billed consumption, and ask whether the opening forecast reflects full operation of shared facilities. Do not assume that a quoted assessment includes a residence's private utility use.
Reserve growth should follow the applicable funding schedule, not an arbitrary percentage borrowed from operating inflation. Florida requires structural integrity reserve studies, or SIRS, for applicable condominium buildings. Structural reserve amounts must reflect the findings and recommendations of the association's most recent SIRS.
For applicable budgets, owners generally cannot vote to waive or underfund mandated structural reserves, subject to statutory timing provisions and permitted exceptions. Counsel should establish the requirements and timing relevant to the purchase.
The amended provisions include a $25,000 base cost threshold for certain components, adjusted annually for inflation. This is not a flat reserve charge payable by every owner. Nor does funding a required annual contribution necessarily mean collecting each component's entire future replacement cost immediately.
Do not underwrite a blanket 15% limit on assessment growth. Insurance premiums and mandatory reserves are excluded from the statutory 115% budget calculation. That provision is not a universal ceiling on increases in ownership costs.
Start with the annual budget for each relevant expense pool. The core calculation is:
Added annual cost = insurance expense × insurance increase + payroll expense × payroll increase + utilities expense × utilities increase + change in annual reserve contributions.
Run one case using increases of 20% for insurance, 10% for payroll, and 10% for utilities. Then run a more demanding case using 40%, 20%, and 25%, respectively. In both cases, insert reserve changes supported by the applicable schedule. Keep other expenses unchanged only as an explicit modeling assumption.
Next, multiply each pool's added annual cost by the residence's governing-document share, divide by 12, and sum the results. Add that monthly increment to the corresponding baseline assessment. Where allocation shares differ, calculate each obligation separately.
For a shortlist that includes The Ritz-Carlton Residences® Sunny Isles, apply the same calculation discipline without importing one property's budget assumptions into another. Comparable arithmetic is useful; presumed equivalence is not.
Before committing, request the latest proposed or adopted budget, first-year assessment package, insurance quotes and deductibles, staffing plan, utility assumptions, available SIRS or reserve projections, and turnover disclosures. Review these alongside the documents establishing tower and shared-amenity allocations.
Ask the review team to distinguish opening costs, full-operation costs, and potential one-time funding needs. Keep special assessments and deductible exposure separate from recurring monthly projections. A stressed HOA figure should not be assumed to capture every obligation.
The strongest ownership decision is not necessarily the one with the lowest opening fee. It is the one whose service expectations, allocation rules, and future funding responsibilities remain clear under pressure.

Begin a quiet conversationThe advertised estimate is $1.70 per interior square foot per month. It is a preliminary reference, not an adopted association budget or guaranteed future charge.
Applying the estimate produces an illustrative monthly assessment of $5,610. That amount is before increases or special assessments and requires confirmation against the assessment package.
Advertised targets are Q4 2028 for the South Tower and Q4 2029 for the North Tower. These are expectations rather than guaranteed completion dates.
Illustrative stress cases use insurance increases of 20% to 40%, payroll increases of 10% to 20%, and utility increases of 10% to 25%. These are scenarios, not property-specific forecasts.
No; apply the insurance shock to the relevant insurance expense, then translate the added cost into the residence's obligation using its documented allocation share.
A square-foot marketing estimate does not establish the legal allocation of every expense. Confirm the residence's share of tower-specific and shared obligations in the governing documents.
Use the change in required annual reserve contributions supported by the applicable funding schedule. Structural reserve amounts must reflect the most recent SIRS where applicable.
The statutory 115% budget calculation is not a blanket 15% ceiling on assessment increases. Insurance premiums and mandatory reserves are excluded from that calculation.
No; it is a base cost threshold for certain components under the amended reserve provisions, with annual inflation adjustments, not a flat contribution charged to each owner.
Request the budget, assessment package, insurance quotes and deductibles, staffing plan, utility assumptions, available reserve studies or projections, turnover disclosures, and allocation documents. Clarify any developer support or phased-occupancy assumptions affecting initial charges.
