Are there any challenges I might face, especially if my long-term tenants aren’t comfortable with the short-term rental activity in the same building?

I have met some great people on my journey, and I am looking forward to meeting more great people here.My relocation is a reset for me.

Passive Activity Losses: Are there ways to offset my W-2 income with rental losses, or do I need to qualify as a real estate professional for that to work?

You will report worldwide income on your federal and Kansas tax returns.You will also include the MO activity on your KS return.Your MO return will only include the acitivity within that state, which in this case, is the rental property.In the future, if you have income in MO(either through the sale of the property or through rental income), you will pay tax to MO but KS will give you a credit for any taxes you pay to MO.best of luck

I don't want to violate any of the self-promotion rules on this thread by specifically linking or name-dropping, but it's from a data analytics platform I am working on specifically built for tracking construction, debt, and ownership activity in the Philadelphia region.I will be posting more detailed insights soon. 

Congratulations on embarking on your investment journey! 

It’s awesome to see you starting your real estate journey so early, congrats.
