THE PROPERTY

Get to know the property.

Set behind the gates of Spanish Oaks overlooking the 7th hole, The Monolith is a rare architectural statement where bold design, extraordinary craftsmanship, and effortless livability converge. Situated on 0.87 acres, the estate offers approximately 9,883 square feet of living space, plus a detached 1,420 square foot casita and separate flex space, creating a true private resort experience.

Striking architecture, soaring 28 foot ceilings, expansive LuxView glass systems, and disappearing walls of glass blur the line between indoors and out. At the heart of the home is the first fully custom Lamborghini kitchen installed in North America, featuring bespoke walnut cabinetry, sculptural stone surfaces, integrated luxury appliances, and exceptional craftsmanship. A fully equipped chef's kitchen is discreetly tucked behind, offering professional grade functionality for effortless entertaining.

The private primary suite includes a dedicated office, fitness room, spa inspired bath with heated floors, imported Italian soaking tub, outdoor shower, custom Italian dressing rooms, and integrated laundry. Additional living spaces include a secondary main level suite, media room, built in office areas, four air conditioned garage bays, and a detached guest house ideal for extended stays.

Designed for year round entertaining, the outdoor living spaces feature retractable shades, a gourmet outdoor kitchen, oversized gathering areas, fireplace, and a dramatic two level pool with a true lap pool overlooking the golf course.

Modern conveniences including Savant home automation, integrated audio, built in shades, and thoughtfully concealed technology complement the home's clean architectural aesthetic.

The Monolith is more than a luxury residence. It is a true one of one.

Purchase price
Rental income & operating costs

Purchase price × 5% ÷ 12. Updates with purchase price until you enter a custom rent.

Annual insurance starts at purchase price × 0.25%, rounded to the nearest available amount. Updates with purchase price until you choose another amount.A planning estimate, not an insurance quote. Adjust it for your property and coverage.

Percentages are editable examples, not ERA fee quotes. Management is applied to rent after vacancy; maintenance and capital reserves use scheduled rent. Add owner-paid utilities, mortgage insurance and other recurring expenses under other costs.

How this scenario is calculated

Annual operating income is rent after vacancy, management, maintenance, taxes, insurance, HOA and other operating costs, before financing and capital reserves. Cap rate divides annual operating income by purchase price. Estimated monthly cash flow assumes an all-cash purchase: rent after vacancy, management, maintenance, taxes, insurance, HOA, other operating costs and capital reserves. No mortgage payment is deducted. The mortgage calculator is separate; loan payments would reduce cash flow for a financed purchase. One-time acquisition costs, renovations, income taxes, depreciation and appreciation are excluded.

Mortgage payment calculator

Explore financing separately. These loan settings do not change the all-cash investor outlook.

Mortgage assumptions

20% down and 7% interest are illustrative starting values.

Estimated monthly principal & interestLoan payment only. Excludes property taxes, homeowners/flood insurance, mortgage insurance and HOA dues.

About this payment estimate

Based on a fixed-rate, fully amortizing loan with monthly payments and the price, down payment, interest rate and term you select. The interest rate is an example, not a current rate offer or APR; APR includes certain loan costs. This is an illustration, not a Loan Estimate, approval, offer of credit or commitment to lend.

Your actual payment, rate and eligibility depend on your lender, credit, loan program and property. Closing costs, points, prepaid expenses and lender fees are not included. Taxes and insurance may change, and mortgage insurance may be required, particularly with a down payment below 20%. Ask your lender for a Loan Estimate and a complete monthly payment including applicable taxes, insurance and fees.

Dollar results are rounded to the nearest cent; calculations retain precision until display. A cash purchase has no loan payment but still has ownership costs. Understand your total home payment (CFPB).
