With where the market is currently at, it's not feasible to maintain that level of staffing and deal flow.

As for your DSCR and Cap rate, again, I would argue technically, they are not calculated in, but often banks will include some form of recurring capex reserve contribution into their DSCR calculation.So, should you consider these items in the evaluation of an asset, YES!  

If I ran a boarding house or hotel as the op has tried to sell it, the place would be staffed.

You'll find with most lenders there will be an LTV reduction of alteast 5% for it being a short term rental and technically considered vacant .

While still technically in seller’s market territory, inventory is well above extreme lows seen in recent years and has held steady for many months now.

Technically, yes.  

That's a good question. it is technically income to the investor.

You could try asking for the HR/Staffing department and see if they can point you in the right direction.

Rental property you financed through the heloc is technically cash flowing on its own.

@Ziad AgarwalTo clarify (sorry if I am being technical)When a hard money loan is in default, for example in Pennsylvania they will send a default notice then file a complaint.
