Meet the Cook Brothers
DSCR loan specialists at Cornerstone First Mortgage. We focus 100% on investment property loans and specialize in rescue closings where other lenders fall through.
Built for Real Estate Investors
Tanner and Zac Cook are DSCR loan specialists at Cornerstone First Mortgage. Unlike most loan originators who split their time between conventional, FHA, VA, and investment property loans, the Cook Brothers focus 100% on DSCR investment property loans.
Their mission is simple: help real estate investors close deals that other lenders can't — especially rescue closings where a deal is about to fall apart because the original lender dropped the ball, ran into underwriting issues, or couldn't perform on time.
With access to 40+ investor loan programs in-house, the Cook Brothers shop every deal across multiple non-QM investors to find the best rate and terms. Whether you're purchasing your first rental property, doing a cash-out refinance to scale your portfolio, or need a lender who can close in 14 days, they have a program for you.
The Team
Two brothers, one mission — get your DSCR loan closed, on time, with the best rate possible.
Tanner Cook
Mortgage Loan Originator
NMLS #2090424
Tanner doesn't miss a detail. He combs through every file and cross-references it against the right investor's guidelines to make sure nothing slips through the cracks. That precision is what keeps deals on track and closings on time.
Zac Cook
Mortgage Loan Originator
NMLS #2111496
Zac is the creative problem-solver. He works closely with every client so they know exactly what their mortgage payment and down payment will look like before they commit — no surprises, no guesswork.
