Buying and Selling a Duplex

[Joshua Savage]

I have been searching for a duplex or multiplex in my hometown because I have to go there every few months and since family and friends are there I probably always will.  With a duplex, I will have a place to stay while I rent the other areas out.  Currently, I am traveling and I do not have a primary residence and so I plan to purchase this home with that type of loan.  However, I will probably buy a home in another area of the country when I do decide to settle down.  Do I have to wait a specific amount of time before I use the same type of loan?  Thanks!
