I am working on a product that will help small-medium size landlords launch and maintain Internet presence at a small monthly cost without spending big budget on custom development.It will include: SEO, custom domain, direct syncing with your property management software, syncing with QB. 

No, but there are many "haunted houses" here in LA including a couple hotels.  

Quote from @Kelsey Vander Meulen: RentRedi includes the ability for tenants to submit a maintenance request.

Often times, counter venders will run deals with sinks included.  

Additionally, the Courthouse Online platform is a helpful tool for property assessment data, including ownership and sale history; you’ll just need your property’s Control Number to get started.The Property Mapper is great for visuals, but it sometimes lags with the latest updates, so checking with the Recorder of Deeds or using Courthouse Online will give you the most accurate information.

Making contacts including HML, contractors, RAs and Property Managers.

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. 

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.
