There are a few pockets that are relatively affordable, but you may have to be patient and act quickly when something becomes available.cheers,Jeremy

Always run a full background check, credit check, and eviction report on any applicant above the age of 18. 5.

But I think there's also a related party issue with the family all being involved. 

@Michele Greene, properties in north Orange County are a mixed bag, very much dependent on which city, which neighborhood, age, HOA, etc. 

My advice to you is to create an LLC with the relative as a capital partner in the LLC.

It's likely I will not have to pay them for anything related to a purchase or sale (included with plan), therefore I'd like to have someone experienced. 

Example: You'll get a better terms (relative to a bank), if a seller has to free-up equity to pay a tax bill or pay the medical expenses.

Assuming all other things being relatively equal (ie you won't be investing in a market that doesn't cash flow, obviously) prioritize people over market.

My company is working on a blog discussing the best age to start investing in real estate.

I work in a companion position to commercial real estate appraisers and as such have had opportunity myself to conduct title searches - one of the houses I mentioned earlier was also an estate property that had been flooded while the relatives sorted the will.
