This past year on the inspection, the inspector needed me to add 1 GFCI outlet in the basement which I ultimately did just because it was easier to do than to fight.  

Things to save money on here and there are painting yourself if you can do it well, light fixtures, GFCI (you need one but not every outlet because you can tie them in with each other), tearout.

I will be putting a section in the lease about living in a historical house that states the house has historical features such as this banister and landing that has a gap of more than 3 inches between the posts, the current standard, and that a child could put his head through the spacing, and that the banister height is lower than is currently used for fall prevention.Other things that are not historical such as putting in the GFI outlets by the sinks, I just do for the safety factor. 

What kind of flowers/bushes/etc?

If you wanted, a flowering tree would be nice on the left side of the house to help frame it out a bit. 

after being gone for almost exactly a month (I left on April 19, got home May 16). 3 weeks of 6 ten-hour-days of hands-on rehab (with a great crew of workers), and another 5 days of before prep, after mop-up & travel.Everything is mostly done -- the tenants are skilled enough to fix the remaining items  - drywall texture, baseboard throughout the house, put in a few doors, replace some outlets, & install a range hood, replace cupboard doors, finish painting touch-up, & replace outside gate.

I would wait until you decide about the landscaping and make sure you coordinate the two so that leaf/flower colors and the door color complement each other.
