McKay Manor is a subdivision in Keystone Heights, the small Clay County city set among the lakes of southwestern Clay County along State Road 21. Keystone Heights grew up around Lake Brooklyn and Lake Geneva, and its neighborhoods are generally quiet, wooded and residential, with the town center, schools and lake beaches a short drive from most streets. McKay Manor shares that lakes-region setting, inside a community served by Clay County District Schools, including Keystone Heights schools. Homes under this subdivision name come to market infrequently, so the character of any given listing depends on the individual house and lot rather than a single development phase. The wider town offers a slower pace than the Jacksonville suburbs to the northeast. View current McKay Manor homes for sale below.
