If I read your question correctly, it seems you are interested in finding investors as partners for commercial properties - yes? I'd suggest tapping into the local real estate investor networking groups. There are a couple in Austin, one is definitely a better time investment than the other.
Every condo downtown has a unique style and feel. Really the only way to experience that is to have spent time in each of the more than 15 buildings. Not only have I experienced each different lifestyle that each offers, but I've written about them on my website:
If you are interested in learning more, give me a call or email, and let's chat about YOUR lifestyle, and which building would suit your needs best.
You could ask your Realtor to send you comparables in the area. The Plaza Loft is close by. You could always stop at the sales office of the new condos being built and get a price list.
Hope some of this helps.
Besides kicking ourselves for not buying downtown 3 years ago, I think there are two schools of thought right now. School #1: CRACK ... someone is on crack building all those high-end projects downtown and someone else is on crack buying them and someone else in on crack pushing the $/sqft barrier or, School #2: MONEY / ECONOMY ... they are selling and there is a lot of money coming into Austin and will continue to come in to Austin. I am more in school #2 with such a solid economic outlook for Austin. And a little side note: Google signing a lease on 6th & Congress is a big deal and, I believe, a sign of things to come. I'm obviously optimistic; not all follow suit. When buying downtown, choose carefully ... some are much better deals than others.... more
