Multiple Loans in Underwriting

[Sarah Linkenhoker]

My husband and I are currently under contract on two properties. 

The first will be our primary residence. The loan is currently in process, appraisal is done but not back yet and I was told it should be headed to underwriting this next week. Closing date is July 22nd, so in 28 days. This financing is being done under my name only. 

The second property is just under contract and we are exploring our financing options. Close date is July 30th. This property is a BRRRR deal that we are looking at financing via a construction loan.

My question is, if we start pursuing this second loan, what are the chances that it screws up underwriting for the first. Is there going to be red flags if they see that we are looking at a second loan? Or is it only the second loan that is going to be impacted? Can I ask my 1st lender this question without getting in trouble?
