Don't forget that many (all?) states in the US use property taxes to fund schools, city services, hospitals etc.
As a result, it isn't uncommon to pay 3% of the assessed value in tax EACH YEAR. Like here in Dallas, if you buy a $300k home, you'll have to pay $9000/year or $750 per MONTH in property taxes. A 30 year mortgage, with 20% down, is still $240k and at 7% interest (reasonable, if it isn't a homestead) principle+interest is $1600/month.
So you pay $2350/month on that investment property. Hire a tax consultant to find a way to deduct interest+property tax from other taxes - not sure, how possible that is for a non-owner occupied home with the owner living outside the USA (as you seem to).
GOOD LUCK finding a renter
who covers that + insurance and wear (homes aren't built to last in the US (after 30 years of rental, the home will be a shack)).
Rentals work for apartments and low-end "slummish" houses (where tax+mortgage are really low - you can buy a $80k shack cash and rent that out for $500/month - that'll probably work).
