just running random numbers wise,
there are probably about 525-550 HOA paying homes in the groves right now. (la vita 70, messina 90-100, saviero 90, vicenza 90, capella 72, amelia 70, trevi ?40, varenna 15-20?)
at $279/home, that is ~150K/mo in dues, or 1.8M/yr.
guard makes what...$17/hr? (no idea). $17/hr*24hrs*2 gates*365 days = ~300K/yr.
that would equate to about $45/mo in dues per home, per year, assuming that the #of homes stays the same (not true) and that there is absolutely no surplus each year (also not true.)
honestly they could probably afford it without too much difficulty.
also, i don't think we are at 75% buildout. alta vista, bella vista, padova, lucca, and varenna are nowhere near buildout. also there is a large swatth of land NE of trevi/amelia that is still unplanned. so there could be a ways to go still.
