What BAANLYY checked, and what it did not

We checked WHO is behind this listing — an agent's government ID against their photo, or an owner's title deed, or a company's Thai registration — before they were allowed to publish anything.
We did NOT inspect this property, check its photographs, confirm its price, size, floor or availability, or check that the person listing it has the owner's permission for this particular home.
Everything in the listing itself was entered by that agent, owner or company. They are responsible for its accuracy, and BAANLYY is not a party to the lease or sale you agree with them. Homes the founding team lists and manages are marked Managed by BAANLYY team.
Never transfer money before you have seen the property or its documents, confirmed who owns it, and satisfied yourself independently. Our check is a starting point, not a substitute for your own.

Years the seller has held this home

Specific business tax or stamp duty depends on how long the seller has held the home (5-year condition). Enter the years above to see which one applies. Usually paid by the seller.

The seller is a company

Withholding tax for an individual seller uses a progressive formula based on the appraised value and the years held, so it is not estimated here. Ask the seller or their agent for the Land Office figure.

Who pays the taxes (business tax or stamp duty, and withholding)?Seller pays allSplit 50/50 (by agreement)Buyer pays all

Withholding tax is usually paid by the seller at the Land Office. A company seller is withheld at 1 percent of the higher of the sale price or the appraised value; an individual seller is withheld under a progressive formula. It is not added to the buyer's cash total unless your contract says otherwise.
