How can I collateralize this property to buy another?

I remember years ago when i looked into loans in japan around 2008 that was the condition. i was kind of shocked it changed when i read that article but they might have been wrong. in any case i dont think i dont think it would make sense in my situation since the units i was looking at are cheap and depreciated out so not much of a collateral. thanks for the insight i read i would have to get a license or certificate or something to operate but didnt know about the cap on days. ltr seems more and more the better route.
