Strongly considering replacing windows in C grade home... good idea?

[Justin C.]

My 1st property will be ready in 2 weeks - May 1st. Its a 1910's style SFH that will rent for $650 p/m which is right at, to slightly lower than market rate. The windows are the original wood and pretty much every one of them has some sort of issue... either rough to open, weights are missing, screens are shot, etc... There are 10 windows in the entire home. I feel that I could raise the rent to $700 if I replaced all the windows. Windows are approx. $225ea installed. The numbers work but I'm hesitant to pull the trigger for some reason. I'm usually one to take action quickly but this one has me stuck. Thoughts?
