Hi Mary,If you haven't found a solution yet, I am currently building an app that has a maintenance tracking feature and maintenance reminders are next in the pipeline. 

Currently have 40 doors which I self manage and looking to upgrade from the simple Landlordy app I currently use to something with more Features so I can focus on having more free time. 

Does anyone know of a free mobile app that i can use to scan receipts, until i can generate funds to  purchase quick books?

  - 7% direct booking commission feels pricey, w/only alternative their DIY 1% basic tier. - Integrated device (locks/thermostats/etc) features are nice, but with only 2-4 devices included in main subscription a clear upsell on larger rentals. 

I noticed Invelo App, but when reviewing the page I saw the bottom deals section.https://inveloapp.com/bigger-pocketsMy comment is when I google search these properties photos on google image I get very different information from real estate property tax history.

Every system you try will have flaws or you'll salivate over a feature that shows up in other software.

It's what I use for my rental portfolio, and they've got a great platform / app.

Alternatively, maybe build for QB's app store?

Hospitable saves me so much time and headache from juggling multiple different listing apps. 

Do not need too many features that I don't need and complicates stuff.I have access to Realtor forms, marketing, etc.
