There's a sweet spot where enough expats bring services catering for them but the DR is a land of excess in terms of real estate. Windeguy is actually right, there is too much construction around Caberete/Sosua.The difference is I spend my time in San Cristobal, usually without spotting any expat or tourist for months.
Nothing against mass tourism or expat cluster’s but it is not for me.
I was bored and set up a web scraper for 1 real estate platform (limited to 120 agencies I could find on that platform) and that brought 21000+ properties for sale of which only around 9000 were under construction. and thats not even all the agencies on that platform. If I add more, the number might double.
I have no idea about the strength of the real estate market here, may be people who were here around the 2008/2009 crash and the COVID dip can say if there was a lowering of prices and sales at that time
