Hi Matt, also check right here on BP.  

If you own the balcony (check CCRs, I have a unit where I don't own my private balcony) then it is all part of the unit.As an owner, you're on the hook for the actions of your tenant.

But it might be a good idea to raise rates each year or so by $50 to $100 because it can communicate that you aren't completely checked out, and you value your property, your time, your investment.

In the meantime feel free to check out a post I did a while back about Cost Segregation - The Basics (biggerpockets.com)

I am also a huge fan of real estate and for the past 50 years there's been a way to combine both.By leveraging a Self-Directed IRA, real estate investors enjoy both the traditional advantages of property ownership and the additional tax benefits of retirement accounts, creating a powerful wealth-building strategy.

Have you checked out Turbo Tenant? 

Deduct NEW property taxes after you buyDeduct home insurance costsDeduct maintenance percentage, typically 10%Deduct vacancy+tenant nonperformance percentage(we recommend 5% for Class A, 10% Class B, 20% Class C, good luck with Class D)Deduct whatever dollar/percentage of cashflow you wantNow, what you have left over is the amount for debt service.Enter it into a mortgage calculator, with current interest rate for an investment property, to determine your maximum mortgage amount.Divide the mortgage amount by either 75% or 80%, depending on the required down payment percentage - this is your tentative price to offer.If the property needs repairs, you'll want to deduct 110%-120% of the estimated repairs from this amount.Be sure to also research the ARV and make sure it's 10-20% higher than your tentative purchase price.As long as the ARV checks out, this is the purchase price to offer.It is probably significantly below the asking price.

I do it myself and takes 20 to 30 minutes a month (did it yesterday for Dec), with about 7 of those minutes for 1 property in Blount County, TN which requires the form to be manually filled out, write a check, address an envelope, scan doc and check for my records and walk it to my mailbox.

Given the property is located in the Poconos and the property is vacant more regularly as an STR there are proactive measures  you should  be taking such as making sure there are heating sources so that the plumbing does not freeze and ensuring there are no blocks in the plumbing lines with routine checks.

It's always better to check with your brother's CPA since he has all the background, but I would say short-term rental with material participation requirements met by your brother, then do cost segregation.
