I think that there's still a distancing of what expats ascertain and what the RE values in the DR are both based on specifics in both.
Whilst in the US or UK RE values are based on demand/supply/greed, in the DR the same formula will not work. A family owns a home in a barrio or residential area of the DR, they want to sell but at the same time they want to sell to move into something better (upgrade). The problem lies in that the price they want to sell for is the same price (just about) of what it will cost them to carry out that upgrade in living somewhere else!
In the DR the RE values are based on the tip principle. Where the RE value of the highest priced properties rank the lower ones. That's to say that as long as the highest segment commands and gets commerce in ever higher values, the lower ranked properties will continue to seek higher values in return.
Take the above pictures as an example, in any other part of the world (pretty much) a property that sits in this hood would command a value that's representative of the residential zone it's located on. But in the case of the DR, the properties here command a value that's representative on equal housing values for the single property and not that of the zone where it's located. That's to say the house you live-in can be sold for an asking price that's equal to that of a property with the same individual qualities, but in a much nicer and higher ranking zone.
Try that in the US or UK RE markets!
The value of the properties in the DR is based on individual aspects and the zone is not the king of the hill, when it comes to the percentage of value as RE in the market.
Another aspect is the boom value. In zones that quality of life is deemed of higher comfort and security, the property values are based on the potential future gains. That's to say that a residential like Villa Olga in Santiago is not longer viewed as the place to settle in a single family home, but to buy several homes and build towers on them. People will be willing to leave behind the luxury and comfort of the single home in exchange for the higher quality of life offered in the apartments that replaced the single family homes.
So what price do you think the remaining single homes have now there?
The same happens in barrios and even campitos all around the country. What today or yesterday was but monte y culebras, now or tomorrow are and will be sought-after property values.
I just recently closed a contract in the Jarabacoa area, where I'd never intended to invest in the first place, let alone think of building a home. Now the reality of the times is much different to that "before".
You can ask for the highest priced property in the DR and I can bet you that within less than 5 to 10 years the value will be far above that last. The problem with RE in the DR remains one based on affordability, and I don't mean the prices, but how people that can't afford the buy in the first place go all out to make it their dream come true soon to become their worst financial nightmare when they need to make it liquid cash...
Of 100 people that use the RE industry in the DR to make money, 90% lose it all or just about break even. The left 10% are the ones that can invest the liquid and not have to convert it in the mid to short term as situations arise due to financial difficulties.
The people behind the Villa Olga project ended up bankrupt after 10 years of the first home built. The people that followed them? Let's just say that their great-great-great-grandkids need not worry of having to work a single day in their natural lives....
