With tax expert service to fill out my tax, can they write an informal report of how much additional tax/ refund I get after adding my 2 rental property?

My rental properties are separate property (instead of community property) and I need to pay those additional tax (or get credits) from/to my separate account.

If you're using the option to have a TTX CPA complete your tax return, you'll have to ask them. Nobody in this public user-to-user forum can provide you a definitive answer. Overall though, I doubt it. As it would require completing two tax returns - one with and one without the rentals. Since not reporting your rental income/expenses is not a choice, I doubt anyone is going to do that.

If you tell the CPA what you want they can enter everything else first ... give you a bottom line,  then add the rental to complete the return.
