You're right about the cash flow in China.  

All of that within the first year should increase the cash flow and therefore the value of that park exponentially I would think...

It's old, a grade D property, but people live there, and it's cash flowing even with 5 units out of 24 vacant.

Vacancies tend to be your biggest cash-flow killers; you also said good tenants can be hard to find in your area. 

You could also be using a different number of payments. 138 is 11.5 years, so I just went into the 12th year at half the cash flow.

It's insane how many deals people will throw your way when they know you only have 45 days to identify (lots of crap with properties that are all priced on pro-forma cash flows!

If it is a great property that will cash flow well you can delay putting in new windows for a bit and then with the extra cash flow have to ability to pay for the windows in a pretty short time frame.

$200-$300 cash flow is a good number after all expenses but I would find a way to increase your COC return. 8% is pretty low but if you can find a way to have less of your cash into the property, your COC will be higher and you'd have more to invest in other properties.

My goal with real estate investing is to build enough cash flow to fund my other business ventures as well as donate to financial literacy programs.  

My question is this: if your goal is to create at least $20k in net monthly cash flow in 8 years, and you have $300k to get started, how would you invest that money?
