Requirements for foreigners to purchase...?

Hello,

You need a KRA PIN to purchase both properties and vehicles.

Property; you don't have to be resident, but foreigners cannot purchase land which has been classified as agricultural.  Only residential plots/properties can be purchased.  Foreigners cannot own freehold property, or residential plots, only leasehold. 

If there is a case where a property is freehold upon purchase, the government will convert it to a 99 year lease.

Vehicles; you need a PIN for purchase and registration.  New vehicles are incredibly expensive, but there are lots of imports of vehicles from 5 - 8 years old, often from Japan.  If you want a diesel, look out for DPF's as these often bring problems, leading to costly repairs.  Ask whether duty has been paid (often quoted as CIF), as this can add 000's to the cost.  If you have a partner who is a returning resident, you can import 1 x vehicle duty free, provided it is right hand drive, under 8 years of age and has been owned for at least a year.
