People responded by explaining that residential mortgage lenders are looking for US-based customers, who have their residence, income and assets in the States.How do they view foreign debt?

But that extra $7200/year will go a long way in paying down your loan faster, build up another downpayment fund, pay off other debt, etc. 

You can refinance it into a conventional loan and that helps avoid the higher down payment.FHA also offers more wiggle room when it comes to DTI debt to income ratios and reserves requirements. 

Consolidate all of your debt if you can.

The key is to understand the capital stack, who is in line in front of you and what are their terms.The people who are getting burned may have known there was debt in front of them, but did they know it was short term or variable - did they know all the details to make a good judgment on the investment.If a property had 20 year fixed debt at 70% would you take that over 3 year debt on a variable rate at 50%? 

Instead we got some smooth sales dude who had hit rock bottom and is now "rich" because he took on debt to do a RIch Dad program years ago.

And after observing @Benjamin Aaker in action I love how he manages his debt. 

These markets often have strong population and job growth and strong rental demand.But the reality is that even in more affordable markets like Columbus, you'll need about $50k-60k household income just to qualify for a conventional investment property loan (this assumes good credit and reasonable debt).

This is regardless of having any debt service.  

Some sleep better at night with zero debt, while others love to use leverage and are willing to take on more risk.Community banks right now will go with 80% LTV.
