I negotiate by offering a year paid in advance with no deposit. Landlords can rarely resist that much cash in one hit. Be prepared though to do any minor repairs yourself ( I can and do ) You won't see the landlord for a year. At the end of the lease you can renew or walk away.
As a farang you can drive whatever you want. But if you are involved in an accident you will be in the wrong. Insurance will mean diddly squat. Worthless. If you have not driven on the roads here then you need to be extremely careful when you do.
