"There is no market for 5+ units?"

[Mario Jaspers Faijer]

Hi BP, 
First time poster, long term listener/reader. I was talking to a lender the the other day and they mentioned they do not lend on MFH with 5+ units. Asking them why they said: "There is no market for 5+ units.". Pretty bold statement given that they are a nationwide lender. Perhaps the market was for mortgages vs. as an investments/rental market.

Wondering what the take is on that from the group? Is this common stance for lenders take, or is there some truth to that statement? 

Appreciate the comments
