I question if their intent is to pander to constituents to get votes rather than make decisions in their constituents best interests.Here is some predictions: 1) rent for existing tenants will go up max allowed increase 2) rents for turned over units will go up far higher than the historical average.  

The biggest cost challenges with them is keeping them "historical".

Newer ones (2008+) are suffering from seasonality now but will pick it up in Q3-Q4: if you look at historical data, Miami Dade county has always had seasonality low volumes during summer time, due to hurricane season, holidays and less tourists visiting. 

Historically, Puerto Rico focused on pharmaceuticals and never got quite as dependent on tourism as places like Hawaii and some other parts of the Caribbean.  

In addition to being a long-term real estate investor I have been a commercial/res appraiser, historic property renovator/contractor, property mgr and more so I don’t mind properties with issues as long as they are fixable and priced accordingly, and my investments are all about the numbers (NOI/Equity).

It's not really that surprising as the big banks have historically not been where these are financed.

Long Term Hold for Appreciation:Pros: Miami's real estate has historically shown strong appreciation, especially in prime areas.

So do your research, but also consider passive investing Visa V syndications or even equity reits, Which have historically outperformed the S and P 500 over 20, 30, fifty years and even outperformed direct, active ownership of real estate by 4 to 6 per cent.

So their historical financials suck.  

Would need to provide year end statements and ideally a way to import prior history in (avoiding re-inputting of the historical data).
