Odds of Hanging On
The real estate market will have its ups and downs, and odds are that your paychecks will be a pretty good indicator of these economic trends. Sticking around as an important (but not entirely necessary) part of the home buying process is going to take planning and tenacity.
When the dry days hit (and they will hit), you need to be ready with savings and willingness to work double shifts all the way through the slump. If you're not that kind of person, you should expect to have a short career run.
