If you wish to open brokerage account for your Checkbook IRA you must open account in the name of the LLC, using LLC's EIN, you as the manager will be signor on the account and will have full control over it. 

If I can control my curiosity, I won't be seriously looking at properties out there again until just before we visit in early April.That being said, when I WAS actively looking, I was looking at properties in areas that had rent comps upward of $750/mo for BRRRR opportunities and the usual hot up and coming areas for potential flips.

If you buy in a suspect area you are really limiting your buyer pool to investor buyers.While the strategy with this property is to sell after the rehab is complete and 2 of the 3 units are filled with tenants, we currently hold 25 units in our local market here in CT and the highest amount of units in a given building is 6.

My only suggestion would be to make sure that you are accounting for all expenses/reserves, including but not limited to the below.
