Browsing through the website has been a great educator for me as well for my plans to invest in real estate in the future. 

If I wait til my credit score goes up, using credit cards and paying them in full every month, could I get to the point in the near future that I could use the 200k for 20-25% down, therefore getting a higher price investment?

Go ahead, efficiency is the way of the future and they will save you good money.

San Antonio is one of the areas I’m looking at sometime in the semi-near future.

One of the standard setup is to have each property in its own single member LLC in the state of the property.The property LLCs are then owned by a holding LLC in WY or NV to benefit from their good charging order protection.In addition, you would use a C corp as management corporation to take salary (if needed to show steady income for future loan approval), retierement, medical and other fringe benefit.

Keep track of your interest costs as well since they will also be his responsibility.Once he is through school, assuming he finishes, you can then rethink your future. 

I have certain amounts that i want to divy up to go towards future expenses (capex etc).

This seemed like an easy process at first, but now I am concerned about the best way to go about this without violating my current loan, a future equity option, and potentially putting this plan in jeopardy.I would like some advice on the best way to strategically go about this process.  

Unless, of course, you may move back into the house in the future and want to keep it for that reason.

So the only way I'm making some money in the near-term future is by getting a new building in my name.
