The ability to effectively self manage would depend on the scale you are trying to buy. 

Quote from @Elvis Diaz: Quote from @Calum Bressington: I want them to be available so bad, I would buy one right away. 

Investment Info:Townhouse buy & hold investment.

If you buy a property with a tenant already there, what if the home needs a lot of rehab when they move out?

Quote from @Jesse Rivera: I disagree about buying in CA.

I only buy positive cash flow and so do my clients.

Creative financing to buy deals is another dangerous approach.

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. 

And what type are looking to buy, SF, 2-4 MF, or 5+ MF? 

There is so much MORE work involved as opposed to buying a fixer-upper and rehabbing that!
