Quote from @Collin Hays: I don't manage short-term any more, but can't you include this in a written rental agreement that the guest signs at the time of booking?

The OP made this math easier for me, since he let us know that he is clearing $2300 a month after all his fees, so that means the only cost he isn't including in that $2300 would be his principal and interest. 

I've talked to lots of California and a few NYC investors that have lost money (including myself) who bought inexpensive properties in the Midwest mostly and a few in the South (Class C is volatile). - some strategies I've seen California investors use to lessen negative cash flow: house hacking, mid-term rentals (people temporarily displaced from home renovation or insurance reasons like fire), rent by the room, Short Term Rentals. - The ultimate house hack, live in the small ADU unit and rent out the two levels of the main house on AirBnb in San Francisco (I would have thought STRs are oversaturated in S.F. but it worked for them and they stay fully booked).

The good news is that there are plenty of great CPAs out there including on these forums.We did have a conversation with him, which is why we selected him in the first place.

yes, get a mortgage securitization audit done with Bloomberg report included.  

However, in the last couple of years, GLVAR modified their PM agreement to include an option for PMs to collect fees while the property is vacant.  

I'd estiamte a pricetag of $20k including panel upograde (although you didn't mention size of house).Problems below vvvv*Unsafe modifications are far more common with K&T wiring than they are with Romex and other modern wiring systems. 

Also, any advice on how to screen tenants would be helpful.

Interestingly, the records do include the downstairs space as part of the livable square footage.

These are amortized payments that include a return of principal each month.
