Importance of loan step cadence (multiple purchases)

[AJ Anderson]

Morning everyone!

My question is in regards to multiple purchases affecting each other in regards to lending. 

We're in escrow and closing on a condo in FL on October 8th. In the meantime, I'm also shopping for a SFH in NC. Obviously the credit run has shown up on my FL closing process but easy to explain, other than that, at what phase of the purchase process (on the NC home) will it start to affect my FL purchase? When the contract is initiated?

I know the easy answer is to wait until 'cleared to close' but I am just wondering for future reference. How do overlapping purchases affect each other?
