I always find it interesting to hear what others are doing and what works best for everyone.I had intended on holding a showing on a Saturday and scheduling times at 15 min intervals, knowing there would be some overlap.

And if you're paying your contractor at intervals, you'll want waivers each time you make a payment and don't make a final payment until you have the final lien waiver in hand. 

If you can't house hack, you could still buy a primary residence and rent out rooms (or the entire property) on weekends or at other set intervals via AirBnB.

We inspect new tenants in 90 days and six month intervals thereafter.

At rush hour time intervals are only 50 seconds.

Instead of trying to time the market trend, time the market by investing in it at consistent intervals, giving you the largest spread, and the most protection.

That said, investing in the S&P 500 or any other major stock index works best when you buy it in small amounts at regular intervals so you get the benefits of "dollar-cost averaging."

Analyze all reports and analyze the work of your support “cast” at the same intervals.

Look online to see if you can find manufacturer's recommended maintenance and intervals, provide him that info as well.

Because certain repair items occur at much longer intervals than "normal" repairs, people tend to place them in a separate category of repairs, often called Capital Expenditures or Capex for short (there are tax reasons too).
