I think that you are missing a few big ones including Zumper, homes, and a bunch of others. 

But before I give you my play-by-play, let me first overview what this concept includes for anyone new to property management or owning rental properties. 

I'll look into the flood risk and I'm always getting an inspection which includes a foundation check.  

Some households receive multiple filings, and not all filings result in evictions.That ranks Phoenix ahead of other big Sunbelt cities that in recent years have also seen an elevated number of eviction notices, including Houston and Las Vegas.

For example including a washer/dryer or allowing pets.

The tenant's month to month lease stipulates that the tenant is responsible for all utilities, including water and I recently spoke to them to tell them the water bill must be paid up and brought current.

The reality is that the tax impact and ability to take ANY losses (as Michael mentioned) is based on a number of factors that include whether or not it is a "separate dwelling unit".

COSTS:  I would look at any-and-all things needed to run an STR including items that are often done by owners--for example, property management.  

@Brian Raike Revisit your goals which you state include cash flow in the future.

The 100 hours rule can be satisfied as long as no one else (including contractors) materially participates more than you.
