Rehab or upgrade financing

[Anna Holmes]

Hello,  I currently travel for work and rent out 3 of my 4 rooms while I'm away.  I'd like to make some rental friendly upgrades and upgrades In general to my 1910 home but don't know where to start.  Out of pocket is slow lol saving up one project at a time with only one salary.  I already managed a 100 to 200 Amp upgrade.  I have no driveway so I put a down-payment on an asphalt driveway. I'd like to replace all my original windows and Instal mrcool split acs and finish the attic.   

advice?

I'm a travel dialysis patient care technician. 

thank you
