Kraig, I think the answer depends on where in Bernal you are buying. In my opinion, Bernal has three major sections: North Slope, South Slope, and South of Cortland (I sure hope we don't end up assigning monikers to these, I'm just identifying the micro markets there).
South of Cortland is an inconsistent area, the lots and streets are generally smaller, and you can find fair housing deals there from time to time. South of Cortland also slopes into the highway and St.Mary's Park. Generally easy access to Cortland shops and restaurants.
South slope is up from Cortland and is generally more valuable, but that again depends on the specific condition of the property. There are southerly views in many of the homes on the south slope. It's easy to get to the top of the hill to walk a dog or take in a panoramic view. Easy access to Cortland shops and restaurants.
North Slope is the more valuable, and homes here can have drop dead views, even if they are somewhat obstructed by trees or another property. North slope doesn't have so much of a walking neighborhood, but Precita park has a few small businesses that buffer that thought.
North slope prices are breaking the $1M mark with properly conditioned properties. South slope pricing is heading that way. South of Cortland you can get into with high 700s, but you should budget as much as 900 for a good offer on a good conditioned property. Bernal is consistently seeing multiple offers on good conditioned homes.
