Ann: Wisr Warehouse Funding Facility Upsized to $250 million, page-12

You can just google "warehouse funding explained" but all it really means in the case of WZR is that they were able to access more funds to lend at an increased margin (originally triple the margin if I remember right)

They still have a portion of their loans on "the old book" with lower margins so as they get paid out or moved to the new method their profit margins per dollar loaned improve.

Long term this obviously gives WZR increased liquidity and the ability to reduce rates and be more competitive or just more easily take on more risk for loans if they choose to do so.

I wish I bought more but I've only ever broken my rule of averaging up once and I won't do that again. Still good buying at this price IMHO.
