Seller financing vs hard money comes down to who you are depending on. With seller financing, the seller carries a note and you depend on one person's willingness, their existing mortgage, and the terms you can negotiate. With hard money, a lender funds the purchase (and usually the rehab) and you depend on the deal's numbers and your ability to finish the project.
Seller financing can be the cheaper and more flexible option when a motivated seller owns the property outright and does not need the cash. Hard money is the better fit when you need speed, rehab money, or a deal that does not hinge on one seller's circumstances. I should say plainly where I stand: I am a hard money lender, and I do not offer seller financing. I have also bought, renovated, sold and held properties myself. This is the comparison I would want if I were on your side of the table.
How seller financing works
In a seller financed purchase, the seller acts as the bank. Instead of receiving the full price at closing, the seller accepts a down payment and a promissory note from you for the balance, secured by a mortgage or deed of trust on the property. You make payments to the seller, and the seller keeps a lien until the note is paid.
Everything is negotiated: price, down payment, interest, payment schedule, whether payments are interest only, when the balloon comes due, and what happens on default. That flexibility is the whole appeal. A seller who wants monthly income, is tired of managing a property, or wants to spread out a tax event may accept terms no lender would. (How a seller is taxed on an installment sale is a question for the seller's accountant, not for you or me.)
The terms only matter if they are written properly. Have a real estate attorney in the property's state draft or review the note and the security instrument. Default remedies, foreclosure procedure and recording rules differ by state, and a note that looks fine on paper can be hard to enforce or hard to refinance out of later.
The due-on-sale problem
The biggest risk in seller financing is a seller who still has a mortgage.
Most residential mortgages contain a due-on-sale clause. Under federal law (the Garn-St Germain Act), that clause is generally enforceable: if the property is transferred without the lender's consent, the lender can demand the full balance. Wraparound and "subject to" structures leave the seller's loan in place under your deal, which means the whole arrangement rests on that lender never calling the loan, or on someone being able to pay it off quickly if it does.
People will tell you lenders rarely enforce it while payments keep coming. That may be true often enough to be tempting, and it is still a risk you do not control. If the loan is called, the seller cannot pay, and you cannot refinance fast enough, you can lose the property and what you put into it. If the seller owns the property free and clear, this problem disappears, which is why clean title is the first thing to check.
Dodd-Frank and investor buyers
After Dodd-Frank, federal rules tightened on sellers who finance homes for buyers who will live in them: ability-to-repay considerations, limits on certain loan features, and in some cases a licensed loan originator. Those rules are aimed at consumer credit. A purchase by an investor, through an LLC, of a property the buyer will not occupy is generally treated as business-purpose credit and falls outside most of them.
That is a general description, not legal advice. State lending and licensing rules can apply on their own terms, and the line between consumer and business purpose depends on the facts. Your attorney should confirm it for your deal.
How hard money works
A hard money loan is underwritten mainly on the property and the plan for it. On a flip, the questions I ask are what you are paying, what the rehab really costs, what the finished house sells for, and whether you can execute. The hard money loan requirements post covers what a complete file looks like.
My fix and flip loans cover purchase plus rehab in one facility, up to 100% of purchase and rehab when the deal supports it. Rehab is funded in draws that reimburse completed work: you front each stage, it is inspected, and the draw is wired the same day. A written term sheet comes within 24 to 48 hours of a complete file, and closing takes 5 to 10 days subject to title. Loans run from $25K to $1M+, close in an LLC, and are for investment property only. There is no prepayment penalty under the terms published on this site; confirm it in your written term sheet.
Terms are set per deal and stated in that term sheet. Hard money is usually more expensive than a well negotiated seller note, and it is short term by design. You are paying for speed, certainty and rehab capital.
Seller financing vs hard money: pros and cons
Speed
Seller financing can close as fast as both sides and the attorneys can work, but the negotiation itself can take weeks, and a seller can change their mind. Hard money runs on a known process: term sheet, appraisal or valuation, title, closing. If you have a contract with a short closing window, a lender with a published timeline is easier to plan around.
Availability
This is the real limit on seller financing. It only exists when the seller wants it, can afford to wait for their money, and ideally owns the property free and clear. Most sellers need their cash to buy their next home or pay off a loan. Hard money is available on any deal that underwrites, whoever the seller is.
Rehab money
A seller note finances the purchase. It does not hand you cash for a new roof. On a property that needs work, you still have to fund the rehab from savings, a partner, or a separate loan. A fix and flip loan is built to fund both.
Flexibility
Seller financing wins here. Terms are whatever two people agree to, including long amortization, interest only periods or a deferred first payment. Hard money terms are flexible within a lender's program, but a lender has standards and a seller does not have to.
Who you depend on
With a seller note, you depend on one person for the life of the loan: their existing mortgage, their estate if they die, their willingness to extend when the balloon comes due. With hard money, you depend on the deal and on your own execution, and on a lender who does this every day. Neither is risk free; the risks are just different shapes.
Combining seller financing and hard money
Some investors use both. The common structure is a lender in first position funding most of the purchase and the rehab, with the seller carrying a smaller second note for part of the price. That reduces the cash you bring and gives the seller some of their equity over time.
It only works if the first lender agrees to it, and many do not. A lender in first position wants to be paid first in any sale or foreclosure, so it will generally require the seller to sign a subordination agreement putting the seller's note behind the loan. Lenders also look at total debt against the property, whether the second note's payments strain your cash flow, and whether its maturity date lands before the first loan is repaid. Some lenders refuse any secondary financing at all.
The practical rule: ask the lender whether a seller second is acceptable on that deal, and get the answer in writing, before you negotiate one into the purchase contract. Discovering a lender policy after the seller has agreed to carry a note is how deals fall apart a week before closing. The subordination language belongs in documents an attorney drafts, not in a clause added to the purchase contract by hand.
When hard money is the better fit
Hard money is usually the better choice when:
- The seller needs cash. Most do. Asking a seller who needs their money to carry a note just shrinks your buyer pool and slows the negotiation.
- The seller has a mortgage. If the existing loan cannot be paid off at closing, the due-on-sale risk usually outweighs whatever you save.
- The property needs real work. You need rehab capital, and a draw-based loan provides it alongside the purchase.
- Timing is tight. An auction, an estate sale or a competitive offer rewards a buyer who can close on a schedule.
- You plan to sell or refinance soon. Short-term debt fits a short-term plan. If you are holding, a BRRRR approach can move you from a bridge into a long-term DSCR loan from the same lender.
Seller financing deserves a hard look when the seller owns the property free and clear, genuinely wants income rather than a lump sum, and the property needs little work. In that case, it can be the best financing you will ever get.
If you are weighing other alternatives to a bank as well, the hard money vs private money comparison covers the other common choice.
Get your numbers in front of a lender
If the seller needs cash or the house needs work, start with the loan. Send me the deal and get pre-approved so you know what you can offer before you sit down with the seller. If seller financing turns out to be on the table, you will negotiate it from strength rather than need.
