For those of you who don't know, I DO help with rentals! There are a lot of good options to rent everything from "high"-rise apartments downtown to garage apartments in back country Greenwich. If you are looking for a family home to rent, we have very low inventory right now due to simple fact that school is open and rarely are families looking to rent when school is in session. This is a very simple, but powerful, rule of renting out homes that applies regardless of the economy.
As for apartment rentals, that market is much less cyclical. Depending on your price range, if you are looking for absolute bottom dollar going to Craigslist isn't the worst idea, though if you want more help in researching and protection going to a local realtor is my ultimate recommendation. For those of you that are coming from the city, realtors in CT are paid by the landlord, so you don't have to worry about any fees. Here are a list of the current apartments, condos and co-ops for rent in Greenwich, Cos Cob, Riverside and Old Greenwich - Greenwich CT Apartments & Condos for Rent. Putnam Park in downtown Greenwich offers some great options as well.
