You have many things in common with the other owners I mentioned.

But would me and my spouse being on the title together and just me as the only solo member in the LLC be a “common ownership” or would it have to be exact and me have both of us as members of the LLC!

This is quite common and we have many duplexes we do this way and haven't had any hassle and in actuality it is much easier for everyone. 

I've built my network through different industries but real estate is a common theme in our investment strategies.

If you are able to purchase as a "tenant in common" then that would work for a 1031. 

What I see most common is borrowers calling thousands of lenders to see who will go the skinniest, only to end up not closing on the deal and paying the price. 

Common sense.

If this HR block person doesn't know (which is common with them sadly) it maybe time for another accountant 

The landlord responded that the lease was not subject to the Rent Adjustment Program since the rental was for “sole use of one or more rooms and shared use of common areas (such as a kitchen) in the residence,” which was a single-family home.In its decision, the court focused on the definition of a “dwelling unit” as used in the exception found in Civil Code section 1954.52(a)(3)(A), which provides that “an owner of residential real property may establish the initial and all subsequent rental rates for a dwelling or a unit about which the following is true…It is alienable separate from the title to any other dwelling unit….” .

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?
