There will always be a few cheap deals around, but I don't think that cheap any longer, prices are back at just below pre-covid levels now.
I have my three units rented and all are just -10% of where they were before covid. But like the base they are good developments. You may get lucky if a local Thai owner has a lot of units mortgaged as these were the guys reducing rents by 50% during covid period just to keep the banks away but most of these are now on the anniversary of renewals so many people in Pattaya are going to get a shock when their rent doubles.
I may be wrong, but you will be lucky to find any modern developments at 6-8K in central Pattaya.
