Being a foreign national, I realise that there is some red tape that I need to overcome; 1) Such as creating a bank account (which I read only two banks offer to create accounts for foreign nationals and I must come to America to create it). 1.1) I've also read that I should open a business account to pay less taxes.

But seeing red flags now and feel business relationships is damaged. 

If you can, use a "streamline" loan which has the least amount of red tape.

That means you're paying $42k in cash and financing $108k, which will bring down your COC return and mean your tenants are paying off less of your investment, which is one of the primary benefits of leverage.Generally speaking, I would say this may be a red flag, but that depends a lot on how the provider handles it.

If not, there may be red tape you would need to get through in order to actually take possession of the property.

But this is also a red flag, the homeowners usually use what Zillow evaluates their home's value, which in all my cases, it's priced at the very high - end. 

@Chris Lin this one has red flags everywhere.

Probably not worth proceeding because of the red flags that are coming up.

You might have to wait for a long time but eventually the bubble will burst and FINALLY you can claim that you saw it coming all along.While I did upvote you for your whitty reply, many areas it is slowing down and sales & prices are dropping, so its really regional vs the entire USA, and even then, like here in DFW, parts are red hot and parts are not moving.

I've worked with a lot of people who are low income and to me it's a red flag.
