Reading on Nextdoor app, it seems that most complaints are about the noise and property crime. 

This is why you really need to review the comp sales versus the subject property to make sure you are comparing apples to apples (or as close to).

For items like decor and furniture the cleaners have to match photos of new stay against previous stay room by room with photos and the EZCare App. 

Any software/camera related, that can be controlled through an app where tenant can have constricted access to cameras but i as owner have full access? 

Every system you try will have flaws, or you may salivate over a feature that appears in other software.Some familiar names are mentioned frequently: Stessa, Apartments.com, RentRedi, TenantCloud, Innago, RentManager, Avail, Rentec Direct, Doorloop, etc.I recommend conducting thorough research on each app online to understand their offerings, pricing, etc.

(But it wasn't apples to apples.)I looked at AirDNA's data recently and don't disagree with their broad picture but again, people here know that the details and other factors can tell a different story and bring success for some in the same area (comparables) and loss for others.I'm all about reducing risk and my read on climate data and global economies (& yes, politics) incline me toward continued investment in properties that have multiple channels of revenue, above a certain latitude, and more upscale.

Now with Google Earth and other apps I can gather enough “feel” for the property to only site visit a property that we are ready to fund2.

I use a combination of CashApp and a website/app called "Rent App" which allows 100% free rental payments, and also helps tenants build credit.

I would say that a good smartlock with a mobile app is always a good call. 

As an STR investor and agent in Phoenix, Arizona, I would utilize your local tax records and look at similar new builds in the area (even if they are in different subdivisions - as long as they are apples to apples).
