You’re analyzing the one neighborhood because that’s where you are right now. I think you’ll probably wind up waiting until the market settles. By the time it does settle you may change your mind about what your options are. Some areas in El Cajon are better than others. If you go west of 3rd Street you’ll probably find the prices for the same types of units are only slighly higher.
You may end up being able to go west instead of east. Who knows, prices may settle so much that La Mesa or San Carlos might be within your reach.
