I was informed by KCMO Health Department that landlords are supposed to be paying an annual fee to them and they conduct inspections of rental units in the city?

For what it's worth, I'm no longer insurance licensed since I took my practice fee only.

Closing Costs – Remember to factor in refi fees and how long you plan to hold the property to determine if refinancing will save you money overall.Since you mentioned owning the property for only a year, your equity might still be limited, impacting your options or leading to higher costs.

What are some things I can do after going under contract to lower closing fees?

Just keep in mind that it's not all about rate and fees - there is a considerable knowledge and expertise component that should be considered as well.

It's why most large landlords use their own in-house tools/software they pay someone a one time fee to setup for them and then hand off. 

I hope to net around $800k after fees and closing costs.

Any bank fees.  

Received a letter that they are more than doubling my monthly fee + a $50 meter reading fee, and unfortunately this is a cost that the state does not allow us to pass along to the tenant!

No one should ever ask someone for up front fees except appraisal fees paid directly to the appraiser...not the lender.
