Personally I love quadplexes.

It’s a balancing act of controlling costs while also controlling risk of personal injury to your tenants and property visitors as well as maintaining goodwill with all involved at the properties. 

If it was me personally, I would not.

If that person were to get hurt somehow and then expect you to pay the medical bills or become disgruntled in some way it is just a phone call to DOR, OSHA or L&I. 

Yes, as I'm doing more research, I'm finding that I would prefer to invest in markets that I know personally, so as not to rely on external variables completely.

I personally target Lauderdale, Limestone, Morgan, and Madison Counties.

So...Assuming we're considering the advantages for American's to invest in Japan, I personally think it only makes sense in a select few situations. 

We actually just had several go in on Livingston ave on the west side where I'd not normally think would be desirable, but they look great and really brought the block up.So I'm a huge fan personally from seeing them go up in my own area.  

@Jason Weidmannit's only solid if:1) you pick a market that you can go to in person and build a team first, and 2) you recognize that RE is a long-term investment, and you may have to wait 5-10 years, or longer, before seeing ANY return. 

If a person wants a different outcome, they usually do something different.
