Lot area is the size of the land parcel itself, in square meters — the ground beneath the structure plus any yard, garden, or driveway.
Floor area is the indoor living space of the structure — add up every story's floor space and that's your floor area. A 2-story house on a 100 sqm lot easily has more floor area than lot area, since the upper floor counts again.
Listings usually show both, e.g. "120 sqm lot / 90 sqm floor area." Confusing the two is the single most common reason a buyer misjudges how big a property actually feels in person.
Single attached — one side of the house sits directly on the property line, usually sharing a firewall with the neighboring unit. Maximizes lot usage, which is why it's common in subdivisions built for affordability.
Single detached — the house stands in the middle of the lot with open space on all sides. More privacy, room for a garden, but a bigger lot is needed for the same floor area.
Where this fits with KayaKo: our Property Type selector (Condominium, House & Lot, Townhouse, Affordable Housing) is about financing eligibility and typical price tier — a townhouse is usually built single-attached, a detached house-and-lot is the "House & Lot" category. Same underlying configurations, different framing for different purposes.
TCT (Transfer Certificate of Title) — the primary title document for land or house-and-lot properties. Names the registered owner and describes the land itself.
CCT (Condominium Certificate of Title) — the condo equivalent. Covers your specific unit plus your proportional share of the building's common areas (lobby, hallways, amenities, the land the building sits on).
Down payment is the upfront portion of the price you pay before the loan covers the rest. Who actually sets the minimum depends on financing type: for bank and Pag-IBIG loans, it's driven by the lender's requirement (commonly 20% is treated as standard, sometimes as low as 10% for certain Pag-IBIG brackets); for developer in-house financing, the developer sets it directly, often 20–30% of the total contract price, frequently payable in installments over months before the loan portion is even released.
Equity, in a Philippine real-estate sales context, is often used as a synonym for that same down payment — "monthly equity" commonly means the installment payments toward your down payment. But equity has a second, different meaning too: your ownership stake — property value minus whatever you still owe on the loan, which grows every year as you pay down principal and (usually) as the property appreciates.
Contract to Sell (CTS) — the seller promises to sell and the buyer promises to buy, but the title stays with the seller until the purchase price is fully paid. This is the agreement you sign first, especially on installment/in-house financing.
Deed of Absolute Sale (DOAS) — executed once every condition is met, usually full payment. This is the document that actually transfers the title from seller to buyer, and what gets presented to the Registry of Deeds to issue a new TCT or CCT in your name.
In short: CTS is the promise, DOAS is the transfer. If a loan is involved, the DOAS typically gets executed once the bank or Pag-IBIG releases the loan proceeds to the seller.
