We invested $17,000 in renovations including repainting, AC installation, refinishing floors, resurfacing kitchen cabinets, and updating bathroom fixtures.Post-rehab, we increased rental income from $650 to $800/month and projected an after-repair value (ARV) of $100,000.

If there is work needed, you'll want to hire a contractor to make the repairs / repaint and cleaned up.

Turn overs take a little more time and effort... we will go in and clean up things that need fixing... like maybe repainting the unit if the walls are looking a little worn / tired.  

A primer and proper cleaning usually solve it before repainting.

The biggest lesson I learned from both the GFC and today's market cycle is:If you go in with a long term mindset, you will (almost) always be fine.Short term debt is not an option if you plan on holding 10+ yrs.Capex budgets become less of an issue (I know of more than a few syndications that have fixed rate long term debt, but are suffering because roofs, repaints, foundation issues, etc are becoming real issues now that the deal is no longer a 3 yr hold, but rather a 8-10 yr hold)And like BRRRs, even refi's start to become more realistic when you budget for long term holds.Yield maintenance/prepayments become non-issues when you intend to hold long term.Lastly, like Brian noted, what I see is that if your goal is long-term security in your investment, typically, you go with well seasoned investors. 

The manager offered to repaint one of the rooms during a turnover and we told him he didn't owe any rent that month.

I did a full remodel—added central heat and air, built a dedicated laundry room, repainted the exterior for curb appeal, and completely changed the layout.

It's been rented for a year and a half and needs repainted.

Really dirty place and that scared my wife, but I wasn't too worried about it as it's mostly cosmetics and we can get the place cleaned whenever they leave.The goal with this first one is to sit on the cash flow, save up it up for 7-10 months and repaint the outside of the duplex.

It's usually cleaning, re-painting, furniture removal, etc.
