While searching the net I found to read certain blogs in Gorilla Bins ( http://www.gorillabins.ca/blog/how-to-start-an-e-waste-recycling-business/ ) about how to start an E-waste recycling business.It seems more informative to me.But still, I need some suggestions from the experienced persons because I am new to this field. please do help me! 

Smoke damage and mold issues and electric meter monkeying/diverting (with huge fines from your utility) will knock any extra monthly you got out quickly.   

I am a small business person in the Inland Empire ( recycling/transportation/business consulting) , that is looking to learn and invest in the Inland Empire.  

We buy them, rehab, place a renter and then refinance cash out original down payment funds and recycle the same funds into the next project - repeat process.  

I see nothing that indicates that the San Diego market going forward will be different than history indicates (but history does show RE cycles so you need to know you can weather a down cycle). 

Lastly, he is still very new in that space and the complete RE cycle story is yet unknown.

We are applying for an ADU in San Mateo, ca. 640 sf 1 bed 1 ba.Just the permit will cost about 10 k, with all the green building, demo recycling, all kinds of bureaucracies.However, the added value is around $800/sf, or $400k ish.The actual building cost we estimate around 100k-130k.

.- Additional subfloor (wood) and cement board (floor) $100- Shower cement board $75- Waterproofing Membrane (I like to do this) $150- Shower wall tile (80-90 SF) $150- Flooring tile (30-40 SF) $100- Tile setting and grout $75- Vanity with top and mirror (24" it looks) $250- Toilet, wax ring and feed line $100- Faucet, feed lines and trap $75- Trim $25- Accessories $40- Fan/light $150- Vanity Light $50- *Shower diverter valve with trim kit and plumber to install and help set tub/drain. $750- Screws, adhesives and fasteners (cement board screws, caulk, etc) $50- Paint $40- Miscellaneous $100TOTAL: $2530With all of that said these numbers would be my BASE run, and assuming I was spending my budget amount on each item.

Should we have a joint bank account separate from our own strictly for the REI business to keep track of funds and cash flow recycling and etc?

I am constantly trying to learn from those who have been through several RE Cycles (the more the better!)
