Basically they missed the loss to lease figure and would be breaking even in the first few years.

That gets worse as you get farther out of the cityTLDR: values depreciate, inflation has gone basically nowhere in Japan for a long time, the supply of housing is pretty good compared to demand (unlike the US) and that's because of flexibility with rezoning and development, taxes on rental income are high. 

Some theming is basic and some is overdone, try to be unique or at least high quality, not a place you want to skimp.

It will familiarize you with the basic terminology and benefits.

Quote from @Erick Pena: A "good" rental property is one that covers all expenses (mortgage, taxes, insurance, maintenance, property management fees, and any other costs) and still leave a surplus (commonly referred to as cash flow).Calculate cash flow as: Cash Flow = Rental Income − Operating Expenses − DebtThere's much more to it, but that's the basic idea.

So I'm basically trying to explore if i can borrow money in an alternative way than conventional loan.

You understand some of the basic concepts, but also have some giant holes in your plan.

For example, I have a subject property that has 1682 SF on the main floor and 810 SF of finished basement (the majority of which is about 8 feet in height with the exception of some bulkheads to hide the mechanicals) and 271 of semi-finished basement that is a utility room basically (washer/dryer, freezer, hot water heater, furnace, some storage).

It will familiarize you with the basic terminology and benefits.

My friend in Big Bear says it's basically vacant unless it's winter.
