Should I get a home improvement loan??

[Chantz Ireland]

I've lived in my triplex for about a month now and have two high ticket items that I think should be taken care of asap. 

1- The roof is starting to leak and hasn't been replaced since it was built in 1983.

2- All the windows are single pane.

Should I get a home improvement loan to knock those two things out at once..? maybe raise the below market rents to compensate for the new payment, or just wait it out and save until I have the funds to do it by myself..?
