I've looked around online for an RE investor or firm looking for something like this, but I haven't seen anything come up.

There are online platforms that will help keep your landlord duties organized, such as avail, buildium, appfolio, etc.

You can also check their reviews online at Google, Facebook, or Yelp.

A lot of this stuff you can figure out yourself online through legal sites but that's why I have my attorney so I don't have to spend the time figuring it out.

First would be to search the online listing, see what's available and practice analyzing/underwriting the deal to make sure it makes sense.

Found them via a crowdfunding platform as a way to pay from the phone app.Parking some money in US dollar Coin on Circle a merchant account we set up to take payments online. it looks straight and pays 7.70% on our account balances.

General question: outside of renting tools from a brick and mortar store, are there any web applications, mobile apps, or online marketplaces where people share construction/remodeling tools peer2peer (similar to turo, Airbnb, etc)?

I found a plumber online, he went in used a snake and it didnt get the job done.

Like TurboTenant and Stessa, is anyone using an online platform that allows you to easily manage your contacts and even possibly your interactions with them?  

We get paperwork and/or it is all listed online in a portal, each payment made and a breakdown of the tenant or address so the bookkeepers know how to apply the rent.
