Real estate agents are well aware of this fact and treat one preapproval letter as toilet paper, and the other as a check waiting to be cashed, accordingly (and obviously advise their homeseller clients as such).

I served 24 years and I am CSM Retired.  

This book saved me and many clients thousands of dollars.

Wholesale deals are not generally considered a 'normal' listing in my world of dealing with clients as an agent and I'm more than happy to simply accept a flat fee. 

I work almost exclusively with investors, and I love the relationships I am able to build with investor clients here in the Chicago suburbs.

I'm trying to help out a client who is a new NFR investor and I'm looking for a property management company. 

A client was rejected for a mortgaage he & his wife combined income is ~$400K.

While I do agree that lenders should do underwriting up front and pre-approve their clients first, this is not yet common enough to pass up offers from those who are only Pre-Qualified.

well one of my clients asked for some flipping loans..

They are wanting a 1 in 10,000 property that would take all my time to find versus other clients (NO).Finding out if a broker/agent and the potential client is a great fit takes work and follow up.
