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

Just know updating the oh so old KNOB AND TUBING ELECTRIC  and all the plumbing.Lessons learned?

Knob and tube, aluminum wiring - just not insurable.And, when estimating rehab costs to make an offer, remember that you're not entitled to "new."

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.

My insurance company, who used to be the only one that would insure knob and tube, now won't even insure aluminum common in the 50s and 60s, so that could be a potential large expense.How is the roof?

I'm not saying this deal isn't good, but I would assume there's old knob and tube electrical in the walls with dangerous splices that have happened over the years.

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?
