I find that health and also style get neglected along the way.

Ensure your property complies with all local health and safety codes.

Just think of all the grief, anxiety and pain they have put you through with this whole situation.

The idea being if mom needs to sell her junky house to a cash buyer in order pay for the care facility plus doesn't have to deal with repairs then hopefully your senior health care network contacts will remember you when they run across this which is supposedly often. 

I would say it depends on if the property is a pain and what your long term goals are.

then start selling the ones that have upcoming major repairs in the next 5-10 years or the ones that are a biggest pain to deal with/make the least amount of money from rent.

As Tony Robbins says, people move away from pain and towards pleasure.

They are going to put in a certain amount of work and their own money on marketing, photos, their overhead costs (agents are independent contractors who pay their own E&O and health insurance, income taxes, MLS dues, NAR dues, continuing ed requirements, etc., etc. all out of their commissions before they get to keep any $), their time, etc. then they also have to split anything they make with their brokerage. $4k would be losing money for me but again it sounds like a lower cost of living area.   

And that is VERY painful for me to say because I LOVE HD, and go there for almost all of our rehab projects.However, if you are leaning toward the White cabinets, I would suggest that you compare to Lowes. 

Like a health cult lol.
