basement- mid-term vs short-term rent spread

[Justiniano Fernandez Campa]

Hello BP of Central VA!
Currently building out a 1,300sq ft unfinished basement in a new development in Waynesboro to include maybe a 2 bed/1 bath apartment/in-law suite. It could be completed for a mid or long-term tenant. OR I could build it out to rent the main house and the finished basement (sans kitchen/furniture etc) to one tenant and make my life easier.  Two separate units it’s a much larger investment. So, I’d love to get some insight into the spread between a long term verse midterm rental for such a basement unit. Read the forums as see that mid-term bring 1.2% -1.5% more than long-term. I understand there are a lot of factors (ie location) but hoping there is an experience landlord out that’s been through this and could weigh in on what is realistic in Waynesboro, VA. Thank you for your time!
