Thanks, Nina Daruwalla
$600K to $700K cannot buy any SFH of Lynbrook or Monta Vista high school for long times.(could be 6 or more years). However you may purchase a Homestead high schoold home. Last year I sold one small home 2bedrooms 1 bath for $605K and another one on 3 bedrooms 2 bath just pending about $725K.
I will be happy to help you.
