Obviously, a lot depends on your price range here and exactly what you're looking for. 

Wow yes I feel like I'm hearing first-hand how wrong it could go, but I have a few questions and concerns if my standards will follow suit of the unlucky investors:-For sure I would want to work with Class A or B rentals (I had a property 5 min from my home and the tenant was HORRIBLE, so a reliable renter is CRUCIAL), but not sure if my price range would find such a tenant.

We are proud to offer a wide range of loan options at competitive rates.

If you go into Central or South Scottsdale (Old Town) $1M will buy you a smaller, older home, OR half of a big, remodeled home (as alot of the Arcadia and Old Town area are turning over old small homes to be big beautiful homes in the $2.5M range and higher).There are options.....for both buying and renting, that would work with your situation.By the way....it's 51 degrees in North Scottsdale right now where I live. 

Most that I sat through are in the 5k range.

In areas like Dallas or Fort Worth, I’ve seen professional cleaning range from $300–$600, especially when dealing with pet-related cleaning like removing cat hair from carpets.

I don't see much waterfront in that price range of 650k or under.

With interest rates on your current properties in the range a stock market portfolio might return paying off the mortgages could be a good option so you maximize cash flow.

Let me know if you have anything in the range of $1 mil- 2.5 mil over 10 + units

Tenantcloud is definitely more comprehensive and has more up-gradable features via reports and such, but the customer service experience is lacking.
