I purchased a solar last year in Cap Cana and am selling it now...any issue with having the buyers wire transfer the monies to my bank account in the USA. I don't have any DR bank accounts.
From experience, I can tell you that it is totally possible to have US dollars wired from a Dominican bank to a US one. However, I would suspect that if the amount wired exceeds $10,000 US, you will have to prove the source of funds.
In the case of my own experience, funds were wired from a US dollar account. Most likely the buyer would have a similar account if you are selling in US dollars.
