First purchase...Did I screw up?

[Craig Dieterich]

I found a small, fully remodeled duplex for $35k in a depressed area of South Carolina with good renters in place bringing in $900/mo in rent, but it had to be a cash deal because it was slightly over appraised price and I also could not find any lender willing to lend that small amount. It will bring in $10,800 in annual rent, but after all expenses (property tax, management, water, and insurance) it will net about $8000 annually. Am I going to get screwed on taxes because I don't have anything to write off (loan interest)? Was it wrong to pay cash for this? What should I have done different? I live in California, so am I going to have to pay South Carolina income tax as well as CA? Is there anything else I didn't think of?
