Long-Term Accommodations in Thailand
Permanent, low-budget housing for about US$160 per month can be found through the smaller real estate agencies.
When negotiating a lease, it's important to be understood. If possible, try to bring along someone who can translate. Also, shop around for an agent that you're comfortable with. The landlord pays the agency's commission, so feel free to contact several agencies simultaneously. They advertise in the Bangkok Post.
A typical lease lasts for a full year. Be prepared to put down two to three months rent as a security deposit. Try to include a "diplomatic clause," which allows you to cancel your lease with thirty days notice in case there's an emergency and you have to leave Thailand. Utilities and a connected phone may or may not be included.
