Many people don't buy because they are concerned about this and that.

I’m looking into buying a rental(s) in this area.

I would recommend you look for a good neighborhood to buy a multi family in.

Look for motivated sellers off market and market via cold calling and or direct mail, geofencing, advertising and the like.A good wholesaler is as @Ericka Parrott mentioned, direct to seller, did good underwriting and can deliver an actual "Deal" whether buy and hold or flip. 

Rents too. 5-10% more reduction and I will be buying here.

Cash flow approximately 350 a month.Option 2: Use the cash to buy land to build a 6 bed 4 bath duplex, all in cost approximately 300k/330k. 

He can't 'buy her out' as he does not have that much cash liquid.

@Ben Callahan, you could find a partner who is looking to buy a similar property, be a co-signer to your partner, and have that person live in it and be a primary resident. 

Investment Info:Condo buy & hold investment.First primary residence (2 bed/ 2 bath condo) located into a desirable part of Southern California.

You can't just go buy commercial RE.
