Your best approach is simply to let the first deal continue as it is and contract separately for the second and treat that as a separate transaction.You can't really delay the first deal without the seller's agreement.Now, I don't know you or your position financially, but you can very well screw up your first deal jumping on another contract unless you actually qualify for both and you won't be hiding the second deal from the first lender, if you tried that could be a much bigger issue.I assume the investing level of sophistication by the questions asked.

I don't think there are necessarily prerequisites from what I've gathered (no commercial real estate background other than 4-plexes), though participants in the commercial real estate space tend to be more sophisticated (e.g., professional). 

I prefer to master simple deals over sophisticated engineering.

MD DC is a sophisticated market, lots of J.D.s.......

Putting an LLC in place to manage the property for a fee converts some passive income to active income that not only gets taxed at your ordinary income tax rate anyway, but, now you also have to pay all the payroll taxes, too.

AS hard as yellow letters try to be very simple like pitching to simple minded folks we go the other way much more polished and sophisticated.

The more sophisticated ones communicate with the utility to allow for both off-peak consumption and the ability for the utility to manage load levels.Once charged, heat is then released into the room from the thermal mass during peak hours ... with minimal electric consumption to maintain the rate of discharge of the thermal mass above a given threshold.

Once you become a sophisticated investor you're typically looking to generate wealth and already have cash to help (rich keep getting richer ideal).

If you simply want to buy an occasional duplex off the MLS, you don't need much sophistication in an agent and really anyone will do.
