With better data you are getting in contact with owners that others are missing by using outdated or static databases (meaning they store their data with no real-time updates) which they update every few weeks or months.I'd say a healthy connection rate for a good quality list is 20%+ where as industry average accuracy on matched data is 40% or so with better providers able to reach 75%-85% with 90%+ in some instances and lists.

It’s totally fine to keep it as one line item on the invoice or receipt.

When inspection was done, we used several items on there to negotiate it down another $10k to $345k.

Check for big-ticket items like roof, HVAC, and plumbing.

Having control over these items is a must for me.  

As soon as an item is placed into service, the lifespan of the item has started.For example if a water heater replacement is $1200 in your market and lifespan is expected to be 10 years, the water heater has maintenance/cap ex o $10/month.    2 water Heaters means $20/month.  

Long as you are not moving walls and no foundation concerns other renovation items are more straightforward (roof, hvac, water heater, paint, flooring and etc) but still get a 2-3 bids to better understand the cost to do the repairs.

I have them sign addendums to the lease that state how to treat areas of the home, ex: kitchen sink, no grease/food items (scrape your plate in the trash) toilet: only the 3 P's, no flushable anything, I even provide them 4 high quality AC filters and have them set a reminder on their phone.I like the phone reminder.

While I suspect nothing is perfect and this is a valid concern, on the call they mentioned items to make it seem secure. 

We have a rental in CO with about 200k equity, and a bit of cash stored, but it's a huge leap to take and i don't feel like my ducks will ever be in a row.
