Suggestions needed for window replacment

[Erik Garland]

Hello Bigger Pocket!! Quick question.  I just acquired a house in a c- area.  I will likely use a minisplit for heating/cooling.  Right now there is a double storm window system.  A few of the interior storm windows need to be replaced. I don't have any experience with this setup.  Should I just replace all interior storm windows with single hung replacement windows or would using new storm windows be alright.  Rent is expected to be 450-500/mth.
