You can structure the partnership however you see fit for yourself and your brother.

The City of Toledo in Lucas County allows up to 4 tote cans to be supplied to an address, so the building has been conditioned to fit their garbage into a specific volume and anytime I have a renovation or move out I have my crew move the debris to a dumpster located at another unit.When we inspected the units we found that almost every unit had a corner of large debris that wouldn't fit in the dumpster, some had bagged garbage staged for placement inside the trash cans when they were next emptied (which contributed to my bug problem).

Everywhere I'm working with now fits that bill if you want to shoot me a direct message and we can chat.

I film YT videos, ship clothing, do online work, etc. out of that home right now.  

Be sure to do your homework to ensure they truly and set up to fit your needs.

The home prices I based on manufacturer web-sites, and yes, (depending on manufacturer) they are pre-fitted with electric, hvac, finish flooring, and insulation.

Look for an inexpensive used car that will fit your needs or as @Amit Kal suggested, ditch the car if possible.  

So where do I fit in? 

It doesn't matter what you do as long as it fits within your goals. 

One could be willing to unload a property or know someone else who is and it could fit your criteria to buy.
