(Most mortgages these days aren't assumable anyway, so unless you know for a fact this one is, it probably isn't.)Re: the "due on sale" clause, various real estate gurus have, over the years, proposed a variety of schemes to try to conceal the fact that the property has changed ownership from the lender, such as putting the property in a trust (which technically does violate the due on sale/transfer clause though it makes it harder for the lender to know).Honestly, I'm not a big fan of those concealment strategies, and I don't think they're likely to work too well in today's digitized world.One way a lender could easily tell if a property had transferred would be that usually the insurance policy changes, and mortgagees (lenders) get notified whenever an insurance policy changes.
