actual insurance, actual taxes, actual utilities, actual capex. 

Those that respond “$0” or something ridiculous, you can request income documentation from them to justify.Don’t be afraid to share with them how much your property taxes & Insurance increased and that YOU cannot afford to absorb them.ALWAYS get an increase or something of value annually or tenants will start thinking they should never have an increase, making future increases that much more difficult to negotiate.

I got a house and have been house-hacking with Air BnB, now is the time that I'm looking for doing the taxes with my W-2 and the Air BnB income, does anyone have any recommendations on an accountant in the upstate South Carolina area that is familiar with doing taxes for real estate investments (ideally specifically short term rental). 

If you have the other expenses, such as the property taxes, water and sewer bills, heating bills if the landlord is responsible for those, electric bills if there is a landlord account, and any other bills you as the landlord would be responsible for monthly you can total them up and see if they will be more or less than the $900/month rent your apartment will generate once you eventually move out of it.

Also your cost associated with holding (utilities paid by landlord or tenants, taxes).

This is a capital gains tax free sale of your personal residence ( up to IRS limits ) and not a loan that will affect your DTI ratio.
