I imagine if I find the other two I'll find this one bundled with it.

I can't imagine you can compare a duplex to a SFH or a duplex to a triplex/quadplex.

Looking at comps, we can probably ask 1500 for the other unit and at least 150 for each garage, but I imagine we'll have to be patient to get up to these costs.  

However, for liability purposes of operating a rental and because we plan to acquire more rentals in the future, I imagine we would quit claim again after the long term financing is in place into an LLC with my wife and I as partners.

However they have no savings for repairs, capex, vacancy, or management.I think if you can find homes in that price range in a decent neighborhood, basically BRRRR them without the refinance, and sell at a price which yields >10% ROI after accounting for all expenses, I would imagine you could sell it quite quickly.I doubt you would even need to go as far as finding a tenant or management company.  

She and her husband aren't moving until next spring, but I imagine they'll reach out to start getting to know agents before then.

Imagine both of your units were vacant and you were advertising for tenants to rent each unit at $800 a piece.

I imagine I could go the route of procuring a conventional loan for the property and a hard/reno loan for the renovations.

I imagine LA is just as bad as San Diego, market wise. 

(We had a slab foundation but I would imagine pier and beam with wood subfloors and floors would dry just like the framing will).
