The sad stories of money lost are too numerous to ignore.

@Christopher Morrisi tend to think of 'cash flow' as a function of an entire portfolio rather than any individual property, or any specific month. 

As for my Airbnb research, I have spoken with a person who runs numerous Airbnb’s in a different area (city atmosphere) who provided good ideas on how to smoothly run the property.

@Sufyan Minhasgoing to depend on the rules in individual buildings

Have you tried contacting the main office or different individuals in the company? 

Certain expenses are all lumped together for the sake of the P&L like insurance and taxes and others like repairs and maintenance can be viewed collectively or by individual property.

Renting an individual room is all but guaranteed to be cheaper than them renting a 1/1 apartment alone.

Search the BP for ADU appraisals to encounter numerous examples.

So, you, as an individual, may not get to the same rate that a MASSIVE national builder can...but you can certainly offer credits to the buyers to help buy down the rates. 

It just obviously won't be market specific.On a personal rezoning I did for a house hack new-construction triplex, I was asked numerous questions about how many bushes and trees I was going to plant.
