Investing in new Subdivision

[Ukaku E.]

Hello everyone,  

This is my first post on BiggerPockets!  And...I want to pick your great minds.

My wife and I moved into a new DR Horton subdivision in New Braunfels, Texas back in April of 2018.  We factored in the possibility of moving out of the property 1 year later and converting the property to a rental.  From the analysis, we would appreciate a modest cash-flow.  

As the year mark is approaching here in April 2019, we are seriously considering moving and acquiring another property.  However, our concern that since the subdivision is still being built out (50% completed) and are worried that potential volume of tenants would be low as these tenants might opt out to buy instead of rent - therefore increasing the properties vacancy period.

From your experiences, is this a valid concern.  Thoughts?

Thank you in advance!
