@Steven Hershey. Unless I missed it somewhere in this thread, there's a big issue which may be getting overlooked. I believe you're talking about buying an investment property. If so, are you assuming you can put down less than 20% and pay PMI like you would on your primary residence?
If so, this is a flawed assumption. Without seller financing or some wildly expensive financial product, you cannot put down less than 20% on non-owner occupied investment property. If that's the case, I recommend going "Dave Ramsey" on your debt first. It sounds like you're pretty leveraged with the student debt on the HELOC. Not a good thing if you're buying at the top of a real estate market which has had a long run up. Consider reducing your 401k contribution to the minimum which maxes out your employer match or suspend contributions altogether for a while if you want to be more aggressive. If you have car payments consider downsizing to cheaper. It will take you longer but you'll do REI better and smarter.
