How would you recommend finding a brokerage with similar interests/goals that could possibly be a sponsor.

Hey Nicholas,Like you mentioned, I'd pay the high interest loans off as quickly as possible. 

I would prefer to hold on to both properties if possible, but if we cannot cash flow (with the HELOC), we cannot do that.

If you are purchasing an investment property, and intend on using for investment purposes only, not personal use, it might be possible for you to rollover the TSP to a Self-Directed IRA and purchase the investment property through this type of structure.

I am looking to possibly buy a lot in Eagle Rock. 

I just returned from a trip to Detroit to analyze a list of properties for the Wayne County auctions happening this September. However, I have apparently missed the deadline to submit a deposit and I'm kicking myself ...

Are they doing everything they can to expose properties to the widest possible market?

@Anthony Dupre depends on the lender. one possible way to avoid due on sale is to time it with Refi.

Most people want out as fast as possible.  

For amount, it would likely be in the $500-700k range.My expectations are to have a negative cash flow while living there, and possibly a slight negative cash flow after moving out (until interest rates lower or rents increase).
