Florida is technically a red state, but like most red states the major metropolitan areas lean blue. 

So here's the bill:1 Service call (July Special) 1.00 $100.00 $30.00(30.00%)No Tax $70.002 Labor (defrost and clean condenser coil) 2.00 $100.00 $20.00(10.00%)No Tax $180.003 Co2 Coil Cleaning 1.00 $25.00 $1.25(5.00%)$1.43(6%)$25.184 R-410a Refrigerant 2.00 $65.00 $0.00 $7.80(6%)$137.80Subtotal (without tax) $403.75Taxes $9.23Grand Total ($) $412.98As an aside, the fact that vendor added refrigerant is a red flag to me, as it's my understanding that cooling systems generally don't lose refrigerant unless there's a leak, in which case the leak needs to be addressed.TL;DR: AC not cooling.

The only red flag I see is the numbers in the bill are estimate not actual

In terms of the car storage idea, as a mortgage broker I would raise at least one red flag to consider: if you ever want to refinance and you have a bunch of cars onsite, regardless of whatever the local zoning permits, that plus the somewhat obvious commercial operating business onsite will be a hard pass from most lenders.

One of the questions asked by insurance companies “are there any pending lawsuits against you or the property….” in your case you would have to answer yes which would raise red flags to the insurance company.  

If he is refusing to leave you may need to hire someone to kick him out and I would imagine a lawyer that specializes in this or a large property manager would have a contact for you.If the lawyer gives you the red light you really have no choice but to wait until the end of the lease term and then not renew the lease.

This way it's 3-5% down, and not a lot of red tape.   

Luckily the market was still red hot in southern california and we managed to get 16k over list price.

I figure there will always be more red tape down the road w KCMO properties, so I should stay in other burbs.

I think many will do as I and many I know have done. a) Exit the Blue state. b) Move to a Red state. c) Find a good conservative county in that state that appears to be landlord and STR friendly. d) Buy properties that can become excellent STRs (to avoid the tenant issue).Or if STRs are not your thing, get to a Red State and do your LTRs or MFRs.
