They sound knowledgeable and like they have your best interests in mind.

Hey everyone, my name is Zach and I am seeking the advice of like-minded individuals with the experience that I have yet to attain.

I am currently stationed at Lackland AFB in San Antonio and plan on investing in buy and hold investing anywhere from San Antonio to Austin, being deployed I have found a few like minded people who also want to get into investing and we have discussed everything from finding deals to funding them to forming LLC's as a safety net, but the first question that always comes up is where to start when we get back.

If you know of someone who is doing well would you mind referring me to them?

I don't think that applies here based on the records I have found so far, but I'll definitely keep that in mind as one of those weird edge cases to try to understand better if I end up getting deeper into this process.3) you call the IRS lien department they can fax you a paper document stating if there is a lien or not its best to have this - unsure about the 120 days start date but we can safely assume it starts once the sale occurs or the date its switched legally in the clerk systems.Maybe calling the IRS will be a bit more enjoyable when it's to talk about someone else's taxes? 

There's a function IRR in Excel that does this for you.  

., make real connections and work with like-minded people as we all chase our dreams!

Keep in mind, this is a duplex and I’m putting 15% down.

Depends on:1 - How many other potential tenants you have lined up2 - How bad you want to make moneyKeep this in mind. 

The first thing that came to my mind is to take all possible expenses in your evaluation.
