to what otherwise is not the simple question
most would readily believe that to be.
Does your lifestyle allow you to purchase a multi unit?
A. Tax Deductions a single family home does not afford.
B. Income a single family home does not create.
C. What if you end up staying longer than you plan?
What if you leave much earlier than you forecast?
What if the size of your household grows?
In all cases - you rent the unit you were residing in...and no problem.
