Budget-friendly options can be found in Maenam, Nathon, and inland Lamai areas, popular among families, long-term expats, and value-seeking investors. Properties further inland or away from tourist centers offer more space at lower prices.

What mortgage options exist for foreign buyers and typical costs?
Foreign buyers can access mortgages primarily for condominiums, not villas or land, with strict eligibility requirements including a 1-2 year Thai work permit and local income of ฿80,000+ per month.
Loan terms typically offer up to 70% loan-to-value ratio with repayment periods up to 30 years. Interest rates for foreigners generally range from 5-8%, higher than rates available to Thai nationals.
Downpayment requirements range from 30-50% of the property value, with some international banks offering similar terms for qualified expats. Strong credit history and substantial documentation are essential for approval.
The limited mortgage availability for foreigners means most international buyers rely on cash purchases or financing from their home countries. This financing constraint affects market dynamics and typically favors more affluent buyers.
