@Mohamad Guene  Simple answer - you will be cash flow negative, and your appreciation will be limited.We did a new build once for a rental - it performed miserably cash flow wise despite a great location and property - we ended up selling it 3 years later.There are very few new builds in Huntsville proper - are you referring to an outlying area like New Market or Meridianville?
