Your choices are limirted at age 53. I am what is referred to as a Seniors Real Estate Special (a sometimes offensive title - I aplogize). 33% of my business is in aiding people like yourself in downsizing.
At age 50, most frequently you can purchase a "new construction", but are limited w/reseales as to the community that allow less than age 55 due to state laws.
If you would like further information, please do not hesitate to contact me direct @ 732.606.2931.
