When are your kids going to be of school age? It costs a lot to keep moving from one part of town to the other if you are going to be buying. If you move to LP there are private schools in the area, though they are fairly expensive.

Co-ops are not set-up for sub-leasing. There is little money to be made by the owner off of that type of arrangement as the montly assessments are high. Many Co-ops have subleasing barred in thier charters.
