Why People Confuse Them
Both can be described casually as:
“Taking over the seller's mortgage.”
That shorthand is dangerous.
Formal Assumption
Typically includes:
- Servicer involvement
- Buyer qualification
- Formal assumption documents
- Defined responsibility
- Seller release considerations
Subject-To
Typically means:
- Buyer acquires title
- Existing loan remains
- Seller remains borrower
- Due-on-sale issues may arise
- Seller retains significant risk
Side-by-Side Comparison
| Issue | Formal Assumption | Subject-To |
|---|---|---|
| Servicer involvement | Yes, required process | Generally not sought |
| Buyer qualification | Yes, through the servicer | Not via servicer approval |
| Who remains on the loan | Buyer formally assumes; seller release confirmed separately | Seller generally remains the borrower |
| Due-on-sale risk | Handled under program/servicer process | Can arise when title transfers |
| Formal documents defining responsibility | Yes | Generally no lender-sanctioned assumption |
Sellers Need to Understand Their Exposure
If someone says:
“I'll buy your house and just keep making your payment,”
that is not automatically an assumption. Before agreeing, understand exactly:
- Whose name remains on debt
- Whether lender consent exists
- Due-on-sale implications
- Insurance
- Default risk
- Credit risk
- Legal documentation
A transfer that merely keeps the seller as the borrower while the buyer takes title looks like an assumption from the outside but carries none of the formal protections. Sellers should recognize that distinction and seek qualified legal guidance before agreeing to any of these structures.
Lisa's Position
When a qualifying FHA or VA loan can be formally assumed, investigate that legitimate assumption route.
Creative alternatives require appropriate legal and lending guidance.
