Partial Assumable on Residential Mortgage - Ever Heard of it?

[Cody Anderson]

I know partial assumable loans were (and still are to some extent) pretty common place in commercial real estate financings, but does anyone know of a residential real estate lender who offers partial assumable loans on individual mortgages? 

Im looking into co-buying SFH and other undivided RE and am curious if anyone's ever heard of a lender doing partial assumable loans (FHA/VA/traditional conforming/etc) for home mortgages?
