I get that the rents are different and that the MH park is MH in name only as it costs a lot to move your home.

You have provided a lot of good information and have given me a lot of information and a lot to think on.

I have gone through my numbers on a few duplexes and after listening to the bigger pockets book I realized there is a lot to go into these calculations. 

But when you mention narrow lot to me that suggest you are more north than south within the Bay Area and therefore demand and prices would be on the higher end of the scale.

So if I start with a duplex or a quad as my first property my goal would be to have a net cash flow of $500I intend to use the "BRRRR" (Buy, Rehab, Rent, Refinance, Repeat) method but have never used this strategy before so I still have a lot to learn If I only close on two deals starting in 2019 then I will need to find another 20 deals in the remaining four years (2020-2024) that also meet this criteriaBeyond 2024 I plan to continue to scale even more over the next 3-5 years with an end goal of financial independence by ~2030 (meaning that I will not work a "day job" but will passively manage my real estate portfolio)Biggest hurdle: I'm going to be living outside of the US for the next 3 years and will (likely) not be able to physically see any properties that I plan to purchase.

As Ozzy says it has a lot to do with your goals and tolerance to risk.

Definitely a lot to look into regarding the tenants and surrounding area.

That seems high but I don't have a lot to compare it to.Thank you in advance.

Cash on Cash Returns have a lot to do with how much leverage you use.
