Short term rentals affect on getting a new primary residence

[Scott Stahr]

My wife are I are looking into purchasing our first short term rental to use as a vacation home and rent out when we're not there.  We are also looking to move into a new primary residence sometime in the near future and are worried that without a long term lease we may not be able to get the home we desire.  How do banks view short term rentals in regards to a new primary residence mortgage?
