Rental Property Question

[Rhys Massengill]

I am new to real estate investing and haven't set up good marketing strategies to generate any quality leads for good deals. I have found some properties that I estimate could cashflow me about $200-300 a month as rentals after all expenses have been paid. However, I'd be paying close to retail price for them. Is this a good idea to buy for the cashflow or should I try to find something better under market value? Thanks!
