Both my sister and brother-in-law are Air Force and Navy vets and utilize VA loans, from my understanding they can be quite beneficial even on investment properties.

You can put them on the inside at the bottom to reduce air flow into your unit. 

@Chase Davidson  You won't believe what a 3BR house with central heat and air goes for in this market

I plan on managing it myself and using cozy for the screening/application/rent collection process.

For the most part if you know the law, use Cozy or Zillow for leasing, and are part of a landlord meetup you can wing it!

If the listing says "central air", or you can see an air conditioner compressor sitting next to the house, but there are window A/C units sticking out of many of the windows, then the central air is broken.  

It all works great in theory, but remember, you are on the hook whether you rent as a profitable air BnB or it stays vacant and you have no income.  

Basically furnaces require air to feed the combustion.

How do a I find a company that can coordinate local property management AND online listings/customer service demands via platforms like Air, VRBO, etc?

I use cozy as well,  and don't really 'send' invoices, but thats how they are tracked in QB.
