Being in south Florida, especially in the Miami market we deal with a large Spanish market. The local ForRent magazine has adapted a Spanish book called “Para Rentar”, which is a bit effective in generating leads, almost same results as putting an ad on the local Spanish newspaper. However, it is my personal experience that similar to the “Haitian” clientele, the best source of advertisement is word of mouth. Spanish and Haitian typically feel more comfortable around their own heritage, so they believe in the inner communication network, where they give each other reference on housing and work. So, I would suggest to ramp up your resident referral program and activities, this should really generate additional leads.
Good luck!
