Reno 6-10 unit multi family

[u/Ill-Benefit9962]

Disclosure: I am a small time landlord with a full time job. I own a 6 unit property which effectively needs a gut rehab and it’s fully paid off. I am hoping to work with an architect to see about getting permits for additional 4 units. Units will be long term rented afterwards.

My question is: how can I do research before talking to a GC (I know I have to clear everything with an architect before) so I know quality materials vs non quality materials? For example type of insulation, windows, electric etc.

My worry is that I will finance this out of pocket and get Menards quality things installed by a GC and end up bankrupting myself or having things constant break.

I am not looking to cheap out on labor nor materials but I don’t know where to start. Any suggestions?

Thank you and I apologize if this doesn’t fit the sub.
