@Jonathan BombaciThanks for all the great tips. 

It's obviously likely a different target demographic than the listings at Pacaso.https://www.airbnb.com/rooms/4...One caveat to their offering is it's early stage so their are some bugs to the platform's app, which is iOS only, Android app on the roadmap, and it's not web-based so you can only participate using the mobile app.

Any tips?

Any tips or advice moving forward?

Any tips for getting a mortgage with putting 20-25% down?

Thanks for the tips!

Along these same lines, an app like Venmo may work with a prepaid card (registered to a network brand like American Express, Discover, etc), but the issue with the daily/monthly send limit would be an issue I think. 

I will be using Bigger Pockets' resources to reach out to agents as well, but any tips/ advice in getting started would be appreciated!
