K.S.
I'm a realtor. I've worked with folks lately looking in the HEB area for a rental, so I'm pretty familiar with the area. I ran a search, but I don't know your pricepoint. If you e-mail me back, I'll send you the listings fitting your criteria.
The MLS has mostly single family homes, duplexes and a few triplexes and fourplexes. A couple of good websites for apartments are move.com and rent.com. There's also apartments.com. Many of the sites had floorplans on line for you to check out.
