It looks like some odd green staining on the siding.

Also, is replacing carpet that’s extremely stained and ripped up in some areas  considered a repair or still an improvement?  

The cheapest option (other than nothing) would be to make a cut in the middle and remove the old, then acid stain the driveway so it all matches. 

-As for repairs, new siding, roof, gutters, light landscaping, chimney repair + sleeve added, boards on deck / stained, re-sided shed, sheetrock, moldings + paint, interior doors, 1 kitchen, 1 1/2 bath, some hardwood floors added and stained, dressed up fireplace, water heater, oil tank removal.

Second, I remind the tenant that if flooring is replaced and they happen to damage it, it will be costly and come out of the security deposit whereas if they damage already very old carpet, they will not be charged for replacement, no matter how badly they may have stained, torn, etc. the carpets upon move-out. 

Im going to place a few coats on the two bedrooms where there isn't much staining. 

Things like the bath sink have nicotine stains but the vanity itself is ok.

This is another lazy landlord installment.This time I want to talk about sprucing up a vanityof you know the vanity that shows the smallest and tiniest scratcheswell I had such a vanity and paid pretty good money for it I was disappointed that it was made from that particle board so that when the veneer scratched off it looked horrible.I decided to take a little minwax stain and rubbed the entire vanity with itthe stain was close in color to the original finishwherever there was a scratch it got dark wherever the finish was the min wax stain just rubbed offI was very surprised by how well this worked.It was so simple I felt I had to share the tipeven if it doesent come out you haven't really wasted any time

@Andrew Johnson  Thanks, the windows and trim are all stained wood and not painted but the soffits could be an issue. 

All current tenants will need evicted, and will probably be stubborn about leaving.My max purchase price if bringing my own financing would be 110k - 120kbeing subject 2 I suspect I can offer more so long as the net income covers all the costs and leaves some positive CF.
