BEST VALUE FOR MONEY Imagimax is 22% below the UAP market benchmark and PHP 1.6M cheaper than Casas for the same floor area. That difference goes into your actual house — not the firm's address. 2. RIGHT FIT FOR THE PROJECT This is a summer house in Laguna, not a flagship commercial project. Casas is a premium Makati firm charging Makati rates. That premium is not justified for a provincial secondary residence. 3. SMART BUDGET ALLOCATION The PHP 1.6M saved from choosing Imagimax can fund: a pool, premium finishes, smart home, landscaping — all things you will actually live with and enjoy. 4. MARKET-RATE PRICING Imagimax's 10.3% rate is fairly priced and within UAP guidelines. No red flags. Clean, straightforward proposal. When Casas would make sense: • If this were your primary residence (not a summer home) • If portfolio/prestige credentials matter to you • If 12-month construction supervision is your top priority • If budget is truly not a concern ════════════════════════════════════════════════════════════════════ NEXT STEPS ════════════════════════════════════════════════════════════════════ □ Request Imagimax's phase-by-phase project timeline □ Request Imagimax's portfolio of similar 400 sqm residential projects □ Confirm whether Imagimax can update scope to 3-storey (500 sqm) □ Clarify construction phase supervision and project management plan □ If proceeding with Casas: Negotiate fee to PHP 3.5–3.8M first ════════════════════════════════════════════════════════════════════ Prepared by: MelAI | April 10, 2026 | Elver Residence, Laguna "Numbers don't lie — Imagimax wins by PHP 1.6M." ⚡ ════════════════════════════════════════════════════════════════════
