Subject-To Deals Explained: Taking Over Existing Mortgages

What Is a Subject-To Deal?

A subject-to (Sub2) deal is when you purchase a property subject to the existing mortgage remaining in place. The deed transfers to you, but the seller's mortgage stays in their name. You make the mortgage payments, but you own the property.

This is one of the most powerful creative financing strategies because it allows you to acquire properties with little to no money down, at interest rates you might not qualify for yourself.

How It Works Mechanically

1. Seller agrees to the deal — they're typically in financial distress and need relief from their mortgage payment
2. Deed transfers — the seller signs the deed to you (or your entity)
3. Mortgage stays — the existing loan remains in the seller's name with the original terms
4. You make payments — you take over the monthly mortgage payment
5. You control the property — you can rent it, rehab it, or resell it

The seller gets out from under their mortgage obligation (you're making the payments). You get a property with built-in financing.

Why Sellers Agree to Subject-To

Sellers who accept sub-to deals typically face one or more of these situations:

• Pre-foreclosure — they're behind on payments and the bank is threatening foreclosure. A sub-to deal catches them up and keeps the foreclosure off their credit.
• Job relocation — they need to move and can't sell fast enough through traditional channels
• Divorce — neither party wants the property and they need to separate finances quickly
• Underwater — they owe more than the property is worth (or very close to it), so a traditional sale would cost them money
• Tired landlord — they have a rental property they're done managing and just want someone to take over

The key motivation: the seller's primary concern is getting rid of the payment, not maximizing sale price.

The Numbers: Why Sub-To Is Powerful

Example Deal

• Property value: $180,000
• Existing mortgage balance: $140,000
• Mortgage terms: 5.5% interest, 25 years remaining, $950/month PITI
• Monthly rent: $1,500

Your acquisition:

• Down payment to seller: $0-5,000 (to cover their moving costs or as goodwill)
• Closing costs: $1,000-2,000 (deed recording, title search)
• Total out of pocket: $1,000-7,000

Your monthly position:

• Rent collected: $1,500
• Mortgage payment: $950
• Insurance/taxes: (included in PITI)
• Maintenance reserve (5%): $75
• Vacancy reserve (8%): $120
• Net cash flow: $355/month

Your equity position:

• Property value: $180,000
• Mortgage balance: $140,000
• Instant equity: $40,000

You control a $180K property with $40K in equity, cash flowing $355/month, with $1K-7K out of pocket.

The Due-on-Sale Clause: The Big Risk

Every mortgage contains a due-on-sale clause — a provision that allows the lender to call the entire loan due if ownership transfers. This is the primary risk of sub-to investing.

The reality: While lenders have the legal right to call the loan due, they rarely exercise it as long as payments are being made on time. Lenders want performing loans, not foreclosures. Calling a loan due on a performing note creates administrative burden and potential loss for the lender.

Risk mitigation strategies:

1. Always keep payments current — a performing loan is almost never called
2. Use a land trust — transfer the property into a land trust with the seller as beneficiary, then change the beneficiary to yourself. This creates a layer of privacy.
3. Don't contact the lender — don't call the bank to tell them about the transfer
4. Have an exit strategy — if the loan is called, be prepared to refinance or sell
5. Insurance in your name — change the property insurance to name your entity, but keep the seller's mortgage clause

When Sub-To Makes Sense

Best Scenarios

• Seller has a low interest rate (especially valuable when current market rates are higher)
• Seller has significant equity (you acquire equity without needing financing)
• Property is in a strong rental market (immediate cash flow)
• Seller is in pre-foreclosure (urgency creates willingness)
• The mortgage balance is favorable relative to the property's rental income

Poor Scenarios

• Very little equity (the property is worth roughly what's owed — limited upside)
• Seller has a high interest rate (you're inheriting an expensive loan)
• Property won't cash flow (rent doesn't cover the mortgage + expenses)
• Complex title situations (multiple liens, judgments, tax issues)
• Seller is not genuinely motivated (they want full market value)

Structuring the Sub-To Agreement

Key elements in your sub-to contract:

• Purchase price and any down payment to seller
• Existing mortgage details — lender, balance, rate, payment amount, escrow
• Seller's representations — current on payments, no additional liens, accurate balance
• Your obligations — maintain payments, insurance, property condition
• Authorization — seller provides you authorization to communicate with their lender if needed
• Exit provisions — what happens if you can't make payments (property goes back to seller)
• Deed type — warranty deed or special warranty deed

Exit Strategies for Sub-To Properties

1. Rent and hold — cash flow monthly while the tenant pays down the mortgage
2. Lease-option — offer a tenant-buyer a lease with option to purchase at a premium
3. Sell on terms — owner-finance to a buyer at a higher price/rate than your underlying mortgage
4. Refinance — after seasoning, refinance into your own loan and pay off the seller's mortgage
5. Sell retail — rehab if needed and sell on the open market

The Bottom Line

Subject-to deals let you acquire properties with existing financing intact — no bank qualification, minimal cash outlay, and immediate equity. The due-on-sale clause is the primary risk, but it's manageable with consistent payments and proper structuring. Sub-to is most powerful when sellers have low interest rates, significant equity, and urgent motivation. Structure carefully, keep payments current, and have an exit strategy ready.
