DC Statutory Resident and Virginia Resident

[CPAQueen]

I live in Virginia but I own a home in Washington DC. 

I have wages sourced to Virginia and some interest and dividend income.

Do I have to file a resident return in both states, tax all of my income in both states?

Do I get a tax credit for income taxes paid to DC in Virginia since it's my home state?

The answer is Yes to both your questions.

If your domicile (your main, primary home) is in VA, and you maintained a place of abode in DC for a total of 183 days or more during the tax year, then your situation is one of dual residency.  You are both a statutory resident of DC and a domiciliary resident of VA.

In this situation you must file a resident tax return (reporting all your income) in both States, but VA will grant you a credit for the taxes you pay to DC on the income taxed by both.  See Dual Residency in this VA tax reference:
