Subject-to vs. Loan Assumption

[Michael Johnson]

This isn't an attempt to be an ***.  I'm honestly curious.  I've been looking over contracts, how to get them filled out, and what all the different things mean.  The standard contract form here in TX doesn't contain anything called "Subject-to".  In fact, I can't find the term anywhere in the contract.  When I do read it over, it seems what we're really doing is assuming the loan.

Please, someone, explain what the difference is.  I'm currently under the impression "Subject-to" or "Sub-to" is just trendy lingo, and largely confusing to people on the outside.  It's even confusing to people on the inside.  =-)

Thanks in advance.
