The class of the title deed
It matters more than the price. A Chanote is the strongest, surveyed form of title; lesser documents carry weaker rights, survey uncertainty and limits on transfer or mortgage. The deed class changes what you are actually buying, which is why it is the first line of any review rather than a technical footnote.
What is registered against it
Mortgages, servitudes, usufructs and registered leases all sit on the title and all survive a sale. A registered lease binds the new owner for its full term, which is excellent news if it is yours and unwelcome news if you were expecting vacant possession. The Land Office record, not the seller’s description, is what settles this.
Access, boundaries and what is actually built
Land without legal access is worth a fraction of land with it. Boundaries on the ground and boundaries on the survey are not always the same thing, and the permit position is compared with what has actually been built — because an unpermitted extension becomes the buyer’s problem the day after transfer.
The seller, and for off-plan the developer
Standing, authority to sell and litigation history. For an off-plan purchase the developer matters as much as the unit: its corporate standing, the project’s own land title and any project mortgage, the permits, and how your instalments are protected before transfer. A beautiful showroom is not a substitute for any of those.
What the findings are for
Each issue is one of three things: a reason to renegotiate the price, a condition to build into the contract, or a reason to walk away. Most are the first two. The review exists so that the third kind is discovered while your money is still yours.
