So I've been told the unit should be replaced, but even that won't fix the core issue that the condenser needs to be installed completely separated from the heating unit and that it needs to be completely free of ventilation hindrances. 

It is right in the downtown core.

You’ll have to repair it after you rip it down especially if it’s a hollow core door, but it can done.  

That brings to the core highlight of this post in-asking: What can Airbnb Investing bring short/long term?

Dollar General and Dollar Tree better credit than Family Dollar.I like upgraded construction stores in suburban core areas.

My thoughts, however, are that we will see urban core, especially high rise, struggle mightily with occupancy. 

@Cj PowderhornC properties in B areas appreciate fast in the urban core of KC.

But at least that would be a lot more compelling. 

What I outlined above seems like your core overall goal, and core what must be overcome to get what you want.Now what you need to do is make a workable plan to get it.You don't need "The Best Plan" just a plan that seems realistically workable, because like everything else in life it will probably be a fluid procedure (vs a static plan) to get what you want.A workable plan might be to figure out how much down payment and closing cost you will need to buy property number 1, and how much equity vs bank loan you will need to hit your monthly income goals vs what you have to put down on it as a minimum.

When the market turns south, they'll start to lose their shirts and run back to the safety of their W-2 job or their core business.
