The in's and out's of a new construction purchase

The clauses that quietly transfer risk onto you tend to fall into a few categories:

• Underpriced allowances. The contract lists a placeholder budget for items you haven't picked yet — lighting, tile, cabinetry. Builders routinely set these too low to make the base price look attractive, then charge you the overage at design center. Get realistic allowances in writing, and watch for double markups on both material and labor.
• Price escalation clauses. Some builders reserve the right to pass material cost increases (lumber, concrete, copper) straight through to you. If there's no cap and no requirement to prove the increase against a public index, your exposure is unlimited.
• Mandatory arbitration. Most builder contracts force disputes into arbitration — often with an arbitrator the builder chose. You waive jury trial and lose most discovery rights. Try to negotiate a neutral arbitrator and a "loser pays" provision.
• Open-ended completion. "Reasonable time" is not a deadline. Push for a firm completion date, narrow force-majeure language, and liquidated damages — a daily penalty the builder pays you for unexcused delays that extend your rent or rate-lock costs.
• Retainage on custom builds. On cost-plus or fixed-price custom contracts, hold back 5–15% of each phased payment until the full punch list is done. It's the most reliable way to keep the builder motivated at the finish.

The myth that new-construction prices are fixed is half true. Builders fight hard on the base price because every discounted sale becomes a comparable that depresses the appraised value of every other home in the community. But they have huge discretionary budgets for incentives and concessions that don't show up on the recorded sale price.

Target these instead:

• Closing cost credits — often $10,000–$20,000, especially if you use the builder's preferred lender.
• Rate buydowns — temporary or permanent. Dramatically lowers your monthly payment without touching the appraisal.
• Design center upgrades — hardwood floors, extended cabinets, appliance packages. The builder's internal cost is a fraction of the retail value you receive.
• Lot premiums — the arbitrary surcharge for cul-de-sac, waterfront, or corner lots is mostly pure margin and very negotiable late in a fiscal quarter or when the builder is closing out a final phase.

Leverage is highest at the end of March, June, September, and December (publicly traded builders chasing quarterly sales numbers) and on a finished spec home that's accruing carrying costs every day it sits unsold.

Pay the builder only for things that change the structure of the home or would be destructive and expensive to retrofit later. A good ceiling on total design-center spend is 10–15% of the base price.

• Architectural changes. Ceiling heights, room extensions, additional windows, shower and tub layouts — these get drafted into the plans and can't really be added later.
• Kitchen cabinetry. Extend uppers to the ceiling (no dust void), soft-close hardware, built-in trash pull-outs, peg drawers, cookie sheet dividers, appliance garages. The kitchen sets the ergonomics of the whole house.
• Electrical and low-voltage rough-ins. Recessed lighting, floor outlets in big rooms, ethernet drops, EV charger prep in the garage, ceiling fan pre-wires. Roughly $100–$350 per item during framing. Fishing wire through finished drywall later means patching and repainting.
• Hardwood on the main level and stairs. Cabinets get installed on top of the flooring — tearing out builder tile later risks the cabinets and forces quarter-round trim. Carpeted stairs damage the skirt boards on removal and the stain almost never matches.

Anything cosmetic and easily swapped is where builder markups are the most outrageous. Take the standard finish and bring in an independent contractor after closing.

• Lighting fixtures and cabinet hardware. A design center might charge $25 for a cabinet pull that retails for $4. Take the free builder fixtures, swap them yourself or with a handyman.
• Paint, wallpaper, and backsplashes. Custom colors and intricate backsplashes carry steep labor markups. Take the standard white, hire a local painter post-close.
• Secondary carpet. Accept the standard carpet in the bedrooms and upper level, but upgrade the pad underneath. Going from a 4-pound to an 8-pound moisture-barrier pad is cheap and dramatically extends the carpet's life.

After you sign and finalize selections, the project can sit for weeks or months before vertical construction starts. That's municipal permitting, utility sign-offs, final plat approvals, and material lead times on engineered trusses and custom windows — not the builder slow-walking you. If you're on a construction loan, make sure your lender is positioned to release the first draw on schedule. On a production home, use this stretch to get every financial document organized for final underwriting.

Done right before the concrete slab is poured. An independent inspector confirms the soil is properly compacted (uneven compaction is what causes differential settlement and foundation cracks years later), checks the placement of rebar or post-tension cables, verifies plumbing sleeves and water lines match the blueprints, and confirms the vapor barrier under the slab is intact. Subterranean moisture wicking up through a damaged vapor barrier shows up later as humidity problems and floor damage that nobody can trace.

This is the inspection that matters most. It happens after framing, roof, and electrical / plumbing / HVAC rough-ins are done, but before insulation and drywall hide everything forever. Skip this and any defect becomes invisible.

The inspector is looking at:

• Framing integrity. Load-bearing walls plumb, joists evenly spaced, structural members not gouged by plumbers or electricians drilling indiscriminate holes for pipes and conduit.
• Electrical and plumbing. Junction boxes accessible, grounds properly bonded, metal nail plates installed over studs so drywall screws don't pierce hidden pipes or wires. Water and gas lines pressure-tested for microleaks.
• Ductwork geometry. Flex duct not kinked, crushed, or sharply turned — any of which strangles airflow and creates static pressure problems you'll be chasing for years.

The single most common catastrophic mistake in modern construction is sizing the HVAC system by square-foot rule of thumb. Today's tightly sealed, energy-efficient homes need real thermodynamic calculations. An oversized AC cools the air temperature fast and shuts off — what's called "short cycling" — without running long enough to pull humidity out of the air. In Florida, that trapped moisture condenses inside the walls and ducts, and you get mold, warped floors, and respiratory issues. An undersized unit runs constantly, never satisfies the thermostat, and burns out years early.

The Air Conditioning Contractors of America publish three protocols the engineering has to follow:

• Manual J — the room-by-room BTU load calculation that accounts for sun orientation, window U-factor, ceiling height, insulation R-values, and occupancy.
• Manual S — equipment selection. The installed capacity should not exceed 115% of the Manual J load.
• Manual D — duct sizing and layout, so static pressure is balanced and air velocity is right, with no whistling or hot rooms.

Ask the builder for the Manual J, S, and D documentation in writing before the equipment is installed. If they won't produce it, that's the entire answer.

The Florida Building Code is the strictest residential wind code in the country for a reason. The right structural features can cut the windstorm portion of your homeowner's premium by 20–50% — documented through a separate Wind Mitigation Inspection (OIR-B1-1802) after closing.

• Hip roof. Slopes down on all four sides. Aerodynamically deflects wind and reduces uplift damage by up to 30% compared to a gable roof. Highest insurance discount.
• Roof deck attachment. Plywood or OSB sheathing nailed to trusses with 8d ring-shank nails, every 6 inches along the edges.
• Roof-to-wall connectors. Single or double hurricane wraps (metal straps that wrap fully over the truss with 3-nail patterns) outperform clips, which outperform toenails. Push for double wraps.
• Secondary water resistance. A peel-and-stick membrane bonded directly to the roof deck. If a hurricane strips the shingles, the SWR keeps water from pouring into your drywall and framing.

Florida Building Code Section R318 requires a documented pre-treatment for subterranean termites — either chemical soil treatment under the slab (protected by a 6-mil vapor retarder so rain doesn't dilute it), localized baiting systems, or borate treatments like Bora-Care applied to the raw framing during the pre-drywall phase. A licensed pest operator's Certificate of Compliance is required before the municipality will issue your Certificate of Occupancy.

On stucco — and especially on EIFS (synthetic stucco) — water that breaches the surface around windows or details gets trapped against the wood sheathing and rots the framing invisibly. Independent inspectors use infrared imaging and pinless moisture meters to find subsurface water accumulation behind newly applied stucco. Have this done before closing.

Strip out the emotion of seeing the finished house and work through it clinically.

• The 4-to-6 foot rule. Assess drywall, paint, and trim from four to six feet away under normal lighting. Anything you can see from there gets marked with blue tape beside the defect (not on top of it), with a brief note and a photo. Don't mark micro-imperfections only visible from six inches — you'll antagonize the punch crews and dilute the real issues.
• Mechanical and plumbing stress tests. Run every fixture simultaneously to check pressure. Fill and drain sinks fast while watching the P-traps. A dry paper towel under each plumbing connection will reveal microscopic drips immediately. Time how long it takes hot water to reach the furthest bathroom from the heater.
• Electrical verification. Every outlet gets tested for proper polarity and grounding. Manually trip and reset every GFCI and AFCI breaker.
• Doors, windows, and cabinets. Open and close every one. Interior doors that drift open or shut on their own mean the frame is out of plumb. Windows should lock with no force. Cabinet doors and drawers should align horizontally and soft-close cleanly.
• Floor topography. Roll the marble across hard-surface floors. Minor rolling is normal — aggressive, localized rolling points to subfloor leveling problems or tile lippage where one edge sits higher than the next.

Everything you flag becomes a formal punch list. Get the builder's written commitment to a specific completion timeline for those items, ideally before final funds transfer and the Certificate of Occupancy issues.

Over the first twelve months a new home goes through what's called "settling." The lumber dries and shrinks, the slab adjusts to the soil underneath, and the structure runs through its first full cycle of seasonal temperature and humidity swings. You get drywall cracks, displaced trim, exterior caulking separations, and popped nails. Roof, insulation, and HVAC all see their first real environmental stress test.

Homeowners who don't document these issues during the warranty period end up eating the repair bill when systemic defects surface a few months after the one-year deadline. Hire an independent inspector at month 11, before the workmanship warranty closes.

A real 11-month inspection covers a forensic look at the attic for hidden roof leaks that haven't yet shown up on drywall, thermal imaging through the wall cavities to find slumped or missing insulation, slow plumbing leaks behind shower valves and inside chases, and exterior siding or stucco separations where pests and moisture can intrude. Submit the report to the builder around 30 days before the one-year deadline. While the warranty is still in force, they're contractually obligated to finance and execute the repairs.

Yes. The on-site rep is a salaried employee of the builder and works for the builder's profit margin — that's their fiduciary duty. Your own buyer's agent negotiates the incentives, reads the contract clauses critically, and brings objective market comps. The builder almost always pays the buyer's agent out of a pre-allocated marketing budget, so this representation generally costs you nothing directly.

The base price almost never is, because every discounted sale becomes a comparable that drags down the appraised value of every future home in the community. But the economic value around it absolutely is — closing costs, rate buydowns, design center credits, free upgrade packages, lot premiums. Push there instead.

Only for structural or destructive-to-retrofit items: ceiling height, room extensions, kitchen cabinets to the ceiling, hardwood on the main level, electrical and data drops behind drywall. Avoid paying the builder for lighting, cabinet hardware, mirrors, custom paint, or backsplashes — the markups are punishing and the work is easy to redo after closing.

Expect it. Weather, supply chain, and municipal permitting backlogs all push timelines. Most builder contracts heavily insulate the builder from delay liability. Stay flexible on your current housing — month-to-month lease extensions are your friend — get a rate lock with generous extension options, and don't book movers until the municipality has actually issued the Certificate of Occupancy.

Independent inspections are arguably the most important thing you do. Municipal inspectors verify minimum life-safety code only — they don't grade craftsmanship, system performance, or whether the upgrades you paid for were actually installed. Hire an independent inspector for the pre-pour, the pre-drywall, and a final walkthrough before closing.

It's the thermodynamic load calculation that determines the right HVAC size for your house, room by room. Builders who skip it and size by square footage end up with oversized units that short-cycle, fail to pull humidity out of the air, and cause mold inside wall cavities and ductwork in our climate. Ask the builder for the Manual J, S, and D documentation in writing.

Schedule the 11-month warranty inspection. Submit the resulting report to the builder about 30 days before the one-year mark. After that deadline the financial burden of those repairs shifts from the builder to you — permanently.
