I have done two down the street from it,,,in Islip Landings.....don't really know if comparible......You may have another issue....what floor are you on??.....I am not sure but I don't really know any complexs that are above two in Suffolk..(Edited to add...except the ones out east...close to where you are headed thurs...)
check Islip landings...there is a SFR phase and a 55 and over phase. I do not know anything about courthouse commons, but that is the closest condo. east islip has beecher avenue ext & heckscher spur. good luck.
