@Brian LeungFor a fourplex in LA/OC - you should in the 6.5-8% of monthly rent range.As a next step, I would suggest asking these companies for referrals to existing clients.

After all, being interested in REI is why I got into property management in the first place.What I'm currently working on is analyzing deals, getting the word out there and building key relationships outside of my existing network. 

Based on the existing mortgage, building cash flows $600-$700 a month with 3 of the 4 units rented. 

Since 1,000 new units in Los Angeles is insignificant, but 1,000 units in a small town are a lot, the figure is sometimes expressed as a portion relative to the existing number of apartment units in that MSA.

So in the event a tenant of mine (or a tenant of any of the other buildings covered by the HOA) floods their unit, the cost of water is paid for by the HOA, either through existing funds or special assessment?

If there is a warning, statement or disclaimer regarding purchaser conducting its own due diligence or similar then the property could easily have been sold subject to existing problems.

The results I have gotten from turning my existing tenant base in to my little marketing army have been unbelievable...

What financing options exist in Central Ohio for financing an investment property without a ridiculous monthly payment?

If your note came due after 2007, you were in trouble unless you had a low LTV and strong pre-existing banking relationships.

Other than rain of course ;) Cost of living was low, taxes were low, personal freedom was high, I really liked the culture that used to exist here too before pretentious yuppie corporate culture completely took over.
