I’ve decided to convert the LLC back to just me being the sole member and to keep the Solo 401k separate.

@Susan O.Non-qualified use is the period of time as a rental (not qualifying as your primary residence).Qualified use is the period you lived in it (qualifying as your primary residence)Your scenario would probably shape up into something like this...Daughter rents for  - 3 years (non-qualified use)You live in it for  -      2 years (qualified us)Total time owned -    5 yearsAmount of exemption available for primary residence - 40% (2/5ths) of the gain up to the $250K limit for you.Plus you recapture all depreciation.And don't forget that a property you convert into your primary residence that was the subject of a 1031 exchange has an overall holding requirement of 5 years. 

(I think)Here is my listing, would you mind giving me honest feedback - https://www.zillow.com/homedetails/7319-Wiegand-Center-Line-MI-48015/83476201_zpid/I prescreen every message to make sure they qualify on paper, the problem is getting them inside and then converting that to a successful application.

I‘m redoing the upstairs unit in an old farm house that was converted into a duplex.

If the property was converted to multi-family after to adoption of the new UDC, you can request a variance/special exception via the Board of Adjustment or you can request a zoning change, which goes through the Zoning Board and ultimately has to be voted on by the City Council.  

I live in the bedroom downstairs, rent out the 3 bedrooms upstairs, and plan on converting the den to a suite-like room to airBnB when I get some free time - mostly just needs some paint and furniture.

@Phillip Denny When it comes to IRA, you can convert an IRA into self-directed IRA account or open SDIRA if you're qualified, or in some cases into solo 401k if you're qualified.

Two layers of industrial carpet (this was a converted motel) and then tile.

A lot of times by taking a two-bedroom and finding a way to chop a big bedroom in half and making it a three bedroom by adding a half or a full bath, or by converting a sunroom into another bedroom or more living space, you can make that property more valuable to give you an equity spread.

I took the lease back to my bank and they converted me into a permanent loan.
