Is this enough info to call a local, very experienced and well-funded flipper and offer a partnership on the deal if it can work, or do i need to make sure it can work first and provide numbers, photos, comp data, repair estimates, etc.? 

Do you get photos of the houses, or no?

The equivalent report on property prices shows that buying will cost you, on average, around €5000/m2 and €3300/m2 respectively.

I know we would then have to save up 20% again for rental #2 but what I don't quite understand is how much time, credit, or equity we would have to build in our respective first purchases before we are able to each get our second.

If they actually come through and the work is done correctly they'll really earn my respect for taking care of all the issues, but I'm not getting my hopes up quite yet.

For protection, I have a massive landlord and umbrella insurance (1m, 2m respectively).

As in driving by at 5am every morning to take a photo of the person's car at the home.

Without seeing photos, the age of the property, and knowing more about prevalent soil characteristics around the area, it's difficult to say.

But in my and @Erin Spradlin 's experience with Airbnb here in Denver, almost everyone is respectful of your place.
