Of course, you want to go with a turnkey provider (if that's the route you go) that keeps annual maintenance costs as low as possible, but there will always be something big that needs a repair when it comes to a long-term investment like that.

I'm not sure how long the tax rate will stay low. 

I can see also why your choosing to do flips in that area as price points are low for San Diego.

Plus a 8 bedroom or even 6 bedroom house is normally considered a party house, because it's exactly what the partiers are looking to rent...the bigger the better.... so you better screen extremely well.

That extra 1.5k a month could really vanish extremely quickly if you have an issue with a rental property or a tenant.

I am extremely interested in real estate investing and currently looking to close my first deal while working full-time as a Director in Customer Relations.

Cash flow is generally very thin due to the cost of maintaining low quality materials, paying lot rent and dealing with bottom of the barrel tenants. 

Property taxes in Cali are very low as compared nationally still. 

I have seen a few parks  empty halfway during the summer time "I am a mailman" That being said there is a market for these homes but the lot rent is going to add up quickly unless you can sell fast and buy at a low cost.

I did some investigation and it seems like a pretty good cash flow scenario with low overhead.
