You can simply convert passive income to non-passive via Sch C via management fees and use Sch C to fund the 401k.

@Rebecca ReadusWhen searching for a vacation home in Orlando with an in-law suite or ADU, consider the following factors: size and layout, zoning and regulations, separate entrances, kitchen and bathroom facilities, outdoor space, location, and budget.Size and layout should accommodate both living needs and potential rental space, with separate areas that could be converted into an ADU.

There is a huge 3-car garage on the property and I was thinking about converting it to an ADU.

I've been making mortgage payments for 9 years with three 1031 exchanges and cannot continue to rent the house longer than necessary because my capital gains taxation will be significantly reduced when I convert it into a residence.

Did you end up converting your rentals to Section 8? 

To convert some of this income to self-employment income simply for the purpose of then making contributions to a retirement plan is generally non-beneficial. 

Do a 1031 into a really nice investment property that later you convert into a primary residence. 

In some states Accessory Dwelling Units are allowed through converting a garage.

Furthermore, for most agents, a higher volume of leads doesn't necessarily help them convert more closings.

I would like to convert my garage into an ADU.
