About Us

Built for the borrower
the bank could not place.

CapitalSource is a structured home equity lending platform operating as both a mortgage brokerage and direct lender.

Deliberate expertise.
Structured solutions.

We specialize deliberately in HELOCs, cash-out refinances, and reverse mortgages structured through non-QM qualification programs that conventional banks do not offer. The result is a platform built to solve what others cannot.

01

Equity

Every solution is structured around the borrower’s actual financial position, led by asset strength, equity, and property value.

02

Structure

We design lending solutions with disciplined frameworks, clear terms, and deliberate risk management.

03

Clarity

We communicate transparently, define expectations early, and remove complexity so clients can make confident decisions.

William Oh

Founder & CEO

William Oh holds an MBA from Columbia Business School and brings over two decades of experience across mortgage origination, capital markets, and private credit.

CapitalSource was designed for the structurally complex borrower: the business owner whose tax returns understate income, the real estate investor whose cash flow does not fit a debt-to-income calculation, and the high-net-worth individual whose wealth lives in assets rather than pay stubs.

“CapitalSource exists because the most financially sophisticated borrowers are often the ones conventional lenders are least equipped to serve.”

Direct.
Transparent.
