Is this even possible or common?

When we were priced out of the SFR market in our area, the Duplex market made more sense as a House-Hack opportunity.

That's a really common toilet issue and most people just jiggle the handle to fix it.

If you all make sense, then I don't see why investors wouldn't invest. 

The one thing we all have in common is that our working vehicles are all well-worn and do not proclaim to our tenants or the rest of the small communities we work and live in that we are making money at this.

@Karla Slyngstad, in your example you would be taking what is commonly called mortgage boot (lessening your debt) to the tune of approximately $345K. 

Factoring your tax liabilities and transaction costs will help you better understand if the strategy makes sense for this situation.

We would like to do a tenants in common deed with her being listed as 80% owner and me being listed as a 20% owner to satisfy the 1031 exchange rules.

I am not sure if this question even makes sense? 

I'd suggest getting to know some investors and real estate agents in town to get a good sense of the market.
