Thai Property Measurements

Thai property measurements are important when buying property as the measurements in Thailand are different to that of the West. If you don’t know how large a Rai of land is then you will need to speak to a property lawyer for assistance in Thailand. Also when you are buying off plan you will need to see if the measurements are wall to wall inside the rooms or does it include the wall itself.

Property Measurements

When buying off-plan you have to ask the attorneys to check that the property has been measured properly. You need to ensure that the measurements are done wall to wall and that these are the measurements on the plan. There are a number of property assessors in Thailand which the Thai banks use and your property lawyer in Thailand would know who they are to do a property inspection.

The assessor will measure the apartment or condo and provide the property lawyers in Thailand with a report on any issues that they see including but not limited to cracked walls or broken water pipes. Without a proper inspection you run the risk of a bad investment.
