In your question you wrote that you are interested in "additional income" with the purchase of a rental. Property in those neighborhoods are good investments in the long term as Daniel earlier pointed out., But unless you make a considerable downpayment when you purchase the property to lower the mortgage paymemt to below what it would rent for, you won't see any positive cash flow (income) for sometime.
Check out Craigslist for rentals to get an idea of rents. A (very) rough idea of mortgage is for every $100,000 it takes to purchase a property times whatever interest rate you can get. If the 1 bedroom/1 bath condo is $250,000, 10% down is $25,000, and finance the remainder of $225,000. So 2.25 times lets say an interest rate of 6.85% you would have an approximate mortgage of $1,541 not including taxes, PMI, HODs, insurance, maintence on the condo, and the cost of the loan itself..
The "good investimate" that buying and renting out the property is would be in holding it for a number of years to sell after appreciation grows enough to give you a good return on the money invested. Over the years rents will rise too, but it maybe sometime before the amount you can rent it for is higher than the mortgage on the rental.
Rents in general are much lower in the short term than mortgages are, time is what makes a mortgage better than rent.
I hope this helps!
