I am curious to what software/programs I should use starting out.

Hey @Mike Allen, I use the Schlage Encode Smart Wifi Deadbolts at my STR - one for the front porch door into the property (it's a duplex), a second for the main entry door into the upstairs unit itself, and then one on the supply closet in the unit for our cleaning team.I don't have any third party management software in place at the moment, and therefore can't speak to the integrations at this point in time.  

Does anyone have any feedback on SimplifyEm property management software?

I can see the use of software and individual coaching. 

Where does one go to find a list of motivated sellers other than paid services like PropStream and other software?

Each software I look into claims to have all three attributes (property, bookkeeping, project).

Does anyone have recommendations on accounting software to best serve STR owners.

Sounds like you're aiming to make some type of algorithm or software that tries to eliminate the need of competent real estate people utilizing their experience in markets they are very familiar with..........Didn't Zillow lose about $500 Million flipping houses using this exact type of model? 

It allows hosts to manage inventory across multiple properties, set alerts for low supplies, and track expenses related to supplies.Breezeway: Breezeway offers a software platform that includes cleaning and maintenance management, but also allows hosts to track inventory and automate supply reordering.These systems typically integrate with booking platforms like Airbnb and Vrbo, making it easier to manage both guest bookings and inventory in one place.

I use software from the hedge fund I work with a hedge fund that connects TO 4500 BANKS, LENDER, AND CREDIT UNION I can take a scenario to add it to my search engine it runs many different quotes so when I'm working with clients I put 5-10 quotes in from of them and save them lots of time and money and they go with the best program that fits the deal
