If I was in your shoes I woukd kiss off Remax at this point. Try super casas and do a lot of your own leg work. There is no such thing as a reputable realtor in the DR.
FWIW, I have dealt with REMAX on a few occasions and was not impressed, at all.
Specifically, I was looking for an apartment to rent, gave the "agent" what I was looking for, and she led me on a goose chase of apartments that did not match my requirements whatsoever.
Her: "Here's a nice 5th-floor penthouse"
Me: "I told you I'm looking for a ground floor"
Her: "But you should take a look at this one"
or
Her: "I have a nice 4 bed/4 bath in Piantini"
Me: "I told you I'm not interested in the center of the city"
Her: "But you should take a look at this one"
And on and on.
Also very elusive about real monthly rent , changed contracts, hidden fees, tried to get me to pay for a contract with incorrect info I walked away from. Also very impolite phone calls from her superiors.
I could go on and on but it was anything goes.
Note: That was 20 years ago. They could be a lot better these days.
