Redwood Trust (RWT) is planning its fifth residential mortgage backed securitization this year.

The last deal came in August, and this one, as the others before, will mimic the successful Redwood RMBS model.

The jumbo mortgages will be transfered from Redwood Residential Acquisition Corporation to either Sequoia Mortgage Funding Corporation or Sequoia Residential Funding, Inc., for wrapping into bonds.

"It’s probably an late Oct/early Nov deal based on the last filing process," said a source familiar with the deal.

The size will likely be similar, around $300 million. Again, the deal is expected to include one or more classes of AAA-rated securities tranches, along with subordinate classes.

The proposed deal is already going to be underwritten by RBS Securities.
