2) Electrical: Because we have no heat, we've been using two space heaters.

We’d like to continue with this project remotely, but the idea of managing contractors and overseeing a renovation from afar feels a bit daunting.Have any of you undertaken a similar project?

One thing to consider on the credit card option is that a lot of contractors don’t accept them so that could be an issue.

My most trusted and often used contractor who lives in the area, and is practically a friend is the emergency contact.   

I even try to unsell them on the business by sharing my financial losses, litigation,  market shifts, permit purgatory, shady contractors,  clouded title issues,  paranormal activity, squatters, mold, etc.

I suggest focusing on building your "Core 4" team—agent, lender (one who can finance both the purchase/rehab and refinance is ideal), contractor, and property manager.

He became a contractor, worked hard, and grew a successful business that produced a lot of money.

What exactly happened with your contractor that went sideways? 

Contractors that specialize in ADUs are all over LA too (and here on BP).

@Anade DavisHi Anade, You’re on the right track with reaching out to your survey and engineering company—they often have strong connections to local contractors.
