Buy and live for x # of years, then rent, How do I calc Cash Flow

[Colleen Marzigliano]

I might have somewhat of a unique scenario, but I am just trying to do the best I can.  My scenario is I am trying to purchase a single family home that is NOT a fixer upper.  The reason is primarily the timeframe.  He is traveling to work over 2 hours a day (crazy).  So, I want to buy a house he can live in for a while and eventually become investment property we can use to rent out.

The plan is to buy a single family home that my son lives in for x # of years.  Once he moves out, I would like to hold and rent the property.  I have tried using the calculators and feel as if they do not help to guide me in this situation. Help?

Let me give a simple scenario we can try to work with: 

* Lets say a house is $100k

* Taxes are 1500/yr

* House could rent for $1000 a month. 

If my family lived in the property for 2 years and then decided to move out. How can I figure out if this property would cash flow positively at that point?

Really appreciate any help, Thanks!
