Here is a quote of Alex Cohen, Lead Commercial Specialist at Core.
“Like many who have enjoyed vacationing in Miami, I was initially drawn to consider buying Miami Beach condominiums as investment about two and a half years ago. However, through assessing condo pricing and condo rents, I quickly discovered that likely returns would be 4% or less. Instead I chose to invest in a unique neighborhood just north of Miami’s hot “design district” called Buena Vista filled with modest single family homes built mostly in the 1930s and 1940s. In Buena Vista, I found and invested in homes that generate for me returns from year-round renters between 5.5 and 8 percent because they make 2-3 bedrooms homes on small lots accessible, particularly to millennial renters, at rents equivalent to what they would pay for a Miami Beach studio or small one bedroom apartment.”
