How much less than 5à per cent should the mortgage be compared to the rentto make some money?

Well, that's exactly how it's been in Europe and one of the reasons why it's by far less lucrative compared to the US.

PVB is relatively more expensive than the greater Jacksonville, it is dirt cheap compared to even the "adequate" parts of Chicago.PVB is a great place to live but the mortgage cost relative to the rental rates are terrible for buy and hold.

The interest is also a little high compared to conventional rates right now, but if you don't qualify for that type of loan--or you are only having to put down a low amount of money--then I think it's not terrible (if it cash flows).

I don't see why not.I heard it's "easier" to get loans for commercial multifamily properties compared to residential because banks see them as more profitable.

I am not sure what the prices are like in the Caribbean or the yield, but I did want to mention another avenue you might want to consider and compare.

How to properly research and compare different mortgage rates?

Compared to last year, many of these companies' sales numbers have shown signs of slowing down and if this continues we'll probably start seeing people losing their jobs, which means people might start missing their mortgage payments, etc.
