I have a lot of extra materials from the first renovation.

These will catch a buyer’s eye in any market, and it's no extra material cost to do so!

Cost to build is $350K (I am managing it all myself and calling in favors around the city to get low rates on materials and labor).

I think it would be beneficial to set up your own management company to manage your assets.

And does the person doing the labor get paid or only the materials paid for by the partnership?

I have a mobile home park in Idaho which will have an onsite property manager.

Once I sell that I’m gonna convert to a fourplex and do the ADU.going through cash quickly and also using credit cards when possible like to purchase materials.

This is for bandwidth and risk management. 

While the cost can vary depending on the scope, zoning, and materials, I’ve seen similar projects run anywhere from $50,000 to $150,000, depending on factors like plumbing, electrical upgrades, and structural work.If you’d like, I can connect you with a few contractors or architects in Chicago who specialize in basement conversions.

@Venka Pulla It’s frustrating when a property manager isn’t meeting expectations, but transitioning to a new property manager is typically straightforward if you follow a few steps:Review the Management Agreement: Carefully read your current Property Management Agreement (PMA) to understand the termination process, including any required notice period.
