It is clearly a buyer's market in this country and has been for quite a few years. With a decent lawyer and assuming no shenanigans with the title/deslinde, one can purchase a property and after a bit of a wait receive their title and everything is cool. One can even stumble upon a bargain from time to time and potentially a property with few hidden/undisclosed defects.
The issues for most present themselves when circumstances change and the foreign property owner needs to leave the DR. Selling a property can be a very time consuming and lengthy process. It's almost a lottery where the right person with the right amount of money needs to be teleported to your property at the right time - something which doesn't happen often these days.
Where I live, I don't see a lot of 70+ year old full time foreign residents. I can only conclude that for most of this demographic, they came, had a good time and then left. For some their exit was due to health issues, others perhaps a death in the family, maybe some economic considerations for some...
I see a lot of properties that have been on the market for a long time that are essentially abandoned - in that no one lives in these properties and they have begun to show the effects of a steady decline from a lack of general upkeep. After a while, spending money on a property that isn't likely to see an imminent sale becomes less of a priority the longer a property remains uninhabited and for sale.
Sure if someone is recently retired, they are committed to living here, intend to be here for "a long time" and reasonably expect to be in good health, purchasing a property free & clear is an option. However, if there exists a known likelihood that a quick exit might be in the cards, maybe renting is a more cogent reality.
For me, I know that my exit plan when the times comes and there is no doubt that someday that time will come, involves getting my first ever facebook account and an ad here on DR1 to announce a week long household goods sale - people come, pick through everything I own and buy what they want at bargain basement prices. After a week, I donate everything that is left to anyone with a truck to haul it away and I hop on plane. I can't envision this happening next week, but much beyond that will be determined by fate. I would not wish to be a property owner saddled with a significant chunk of hard earned change sunk into a property that I would likely never use or see again. I suspect that like so many others in this exact situation, with no family here and no one in the family able or willing to live in the DR, such a property would join the list of so many other properties that seemed like a good idea at the time and even served their purpose for some period of time, but ultimately now sits empty, becoming more and more unsellable with each passing day.
