StackSource's story

StackSource is a growing commercial real estate financing portal with more than $2 Million of revenue, poised to change the real estate finance industry. Here's our story.

How Real Estate Finance works

Real estate investors that buy commercial properties aren't too different from home buyers. They don't buy these properties with cash - they take out a commercial mortgage loan. The better the rate and terms for this loan, the more money they make on their real estate investment.

There are thousands of commercial mortgage lenders out there, and no easy way to access and meaningfully compare the universe of available loan programs. As a result, borrowers typically go to their existing relationships, like the local bank, or use a traditional loan broker that will funnel the borrower to their preferred contacts. Either path frequently results in wasted time, aggravation, and missing a lender that has a better rate or more favorable terms.

That’s especially true right now. Lenders large and small have been adjusting their lending parameters frequently to account for an uncertain economy. The bar to obtain financing is higher, and finding favorable terms is less certain.

Loan brokers have a wider network, but are usually difficult to work with. Their process is a black box, it’s slow, and there can be undisclosed fees built into the back end. Above all these guys are old school - there’s little to no transparency after signing an exclusive engagement letter, long before they come back with one or two financing options.

StackSource brings transparency to the financing process for real estate investors. We instantly match loan requests submitted via our portal with relevant loan programs from our network of lenders, and automate much of the arduous process of applying to receive real loan quotes.

How StackSource works

We make the process as simple as possible to find and compare competing commercial mortgage options.

But we don't leave them to sink or swim alone. StackSource's team of Capital Advisors provide help, advice, and negotiation expertise through the process. While the process is as simple as possible for the borrower, the Capital Advisors have a suite of more powerful features on the back end to manage and work with StackSource's 700+ lending partners.


StackSource's organic leads from borrowers increased dramatically in 2020. The real estate industry was already moving toward digital services and transactions - COVID lockdowns only accelerated that trend. 

We closed our 100th real estate loan in November 2020. Unlike a local loan brokerage, these loans were placed in 27 different states across the country.

The top “cloud-based” residential real estate brokerage increased its stock price by 450% in 2020, while the parent company of Rocket Mortgage went public at a $40 Billion valuation. 

While the commercial mortgage market was affected by COVID in 2020, StackSource's loan volume and revenue both grew significantly.

StackSource's current loan pipeline continues to grow so fast, we have more loan volume in the pipeline now than our total, lifetime loan volume.

StackSource is ideally positioned to become the leading distributed, cloud-based commercial financing platform.

What's next for StackSource

StackSource has an early lead in online shopping for a commercial mortgage. 

But we’re not satisfied to only be a faster, sleeker commercial mortgage brokerage. We can change the game fundamentally.

Underwriting for certain loan segments, and should be, streamlined. Properties with predictable cash flows can be instantly quoted with a high degree of accuracy, given the right data. We’ve identified three large segments of the market where we can produce accurate, real-time soft loan quotes.

But if we can provide instant loan quotes on our platform, why stop there? Why not let users bring the power of instant loan quotes on the go, to any commercial property listing across the web?

That's where our new patent-pending Browser Extension comes in.

We'll also make the loan quote engine available to partner websites and platforms via a Loan Quote API starting later in 2021.

Keeping our lead with the best tech platform in the industry will be key to StackSource's success. We're redefining real estate investors' expectations from their financing provider.
