How to Use Seller Financing to Lower Your Cost of Capital

My mountain house. My island. My primary beach home in Charleston.

All three of those were seller financed. In each case, the seller was over 60, had owned the property for years, had significant equity or owned it free and clear, and understood what they were actually being offered: a hard asset backing a fixed income stream that outperforms what a bank account pays. They didn’t need a lump sum. They wanted reliable income. Seller financing gave them that, and it gave me a lower cost of capital on properties I wanted to own long term.

That’s the basic logic of seller financing — and once you understand it, you start seeing opportunities for it everywhere.

Why Sellers Say Yes

Most people think seller financing is something you ask for when you can’t qualify for a traditional loan, or when a deal has some problem a bank won’t touch. That’s a limiting way to think about it.

Seller financing is a tool that benefits a specific type of seller: someone who has owned a property long enough to have real equity, doesn’t urgently need all their proceeds in a lump sum, and understands that spreading that income over time has tax advantages and often earns more than parking the money elsewhere.

The tell-tale signs that a seller might be open to it: they’ve owned the property for a long time (which means they’ve paid down significant principal, or bought at a low enough basis that they have substantial equity), they’re older and financially sophisticated, and they’re not in a distressed situation where they need to liquidate immediately.

Mortgage records are public. You can cross-reference when a property was purchased with county documents on when mortgages were filed, what the typical loan terms were at that time, and roughly how much has been paid down. Companies sell lists built on exactly this kind of data. If a seller has owned a property for 20 years, bought it at 1990s prices, and has a loan that’s mostly paid off — or no loan at all — you have a potential seller financing conversation.

The Capital Structure Most People Don’t Think About

Here’s where it gets interesting for multifamily investors specifically.

When you’re buying a larger deal, your capital stack typically has a few layers: a bank loan for the senior debt, private investor money for the equity or mezzanine piece, and whatever you’re bringing yourself. Private investors — the LPs coming into a syndication — are new to the deal. They’re taking on risk. They’re going to want 8% to 10% preferred returns and equity participation. That’s the market rate for new capital.

But a seller isn’t new to the deal. They know the asset intimately. They’ve owned it for years. They’re already getting their full purchase price from the bank loan and whatever cash you’re bringing. The portion they’re willing to roll back in isn’t a leap of faith — it’s staying in something they already understand.

Because of that, they’re often willing to take significantly lower terms on the seller carry piece. Instead of 8% to 10% with equity, you might get 3% to 4% with little or no equity given up. That difference in cost of capital compounds significantly across the life of a deal.

A Concrete Example

Say you’re buying a $10 million property. You get a bank loan for $7 million. That leaves $3 million to raise.

Option A: Raise all $3 million from private investors at 8% to 10% preferred return with equity participation.

Option B: Get the seller to roll $1 million of their proceeds back in at 4% with no equity, and only raise $2 million from private investors.

In Option B, you’ve cut the amount you need to raise by a third. You’ve reduced the equity you’re giving up. And the $1 million you did bring in from the seller costs you half what the same capital from a new investor would cost. Your blended cost of capital drops, your cash flow improves, and you gave up less of the upside.

The seller still gets their full purchase price — they just receive part of it over time instead of all at once. If they’re financially sophisticated and not in a rush, that’s often a trade they’ll make.

Always Ask

Here’s the thing: even when the deal looks like it will work without seller financing, it’s worth asking anyway.

You’re always going to need some down payment capital regardless. That money is either coming from your own pocket or from private investors who want market-rate returns and equity. Any portion of that you can replace with lower-cost seller financing is a better outcome for you.

The seller is already getting what they wanted — their sale price. They’ve already decided to sell. The question of how they receive their proceeds is a separate conversation, and one that a financially sophisticated seller is often happy to have.

Create two classes of participation: one for the seller at their terms, one for your LPs at market terms. The structures don’t need to conflict. The seller typically wants security, a predictable return, and simplicity. Your LPs want returns and equity upside. Those are compatible.

The worst thing that happens when you ask is they say no. You’re no worse off than if you hadn’t asked. But when they say yes — even on a portion of the deal — it makes the whole thing work better.

The Bigger Picture on Cost of Capital

Understanding your blended cost of capital — what you’re paying across every layer of debt and equity in a deal — is one of the most important skills you can develop as a multifamily investor. Seller financing is one of the best tools for bringing that number down.

The investors who consistently do better deals aren’t always finding better properties. A lot of the time they’re just structuring them more intelligently, bringing in cheaper capital, and keeping more of the returns for themselves and their LPs. Seller financing is a meaningful part of how that happens.

If you haven’t been asking about it on every deal, start asking.
