I've included an example below to help illustrate this.So different lenders have different rates (which do vary even for DSCR loans) but these are factors they all consider.See example below:DSCR < 1Principal + Interest = $1,700Taxes = $350, Insurance = $100, Association Dues = $50Total PITIA = $2200Rent = $2000DSCR = Rent/PITIA = 2000/2200 = 0.91Since the DSCR is 0.91, we know the expenses are greater than the income of the property.DSCR >1Principal + Interest = $1,500Taxes = $250, Insurance = $100, Association Dues = $25Total PITIA = $1875 Rent = $2300DSCR = Rent/PITIA = 2300/1875 = 1.23If a purchase, you also generally need reserves / savings to show you have 3-6 month payments of PITIA (principal / interest (mortgage payment), property taxes and insurance and HOA (if applicable).

You clearly have factored this in already.

I'm sure they are out there but this is just a rule of thumb and I would rather use J Scott's approach when he analyses deals outlined in his book.You factor in your desired profit as a cost and you work backwards.

Recently, a lot of the market factors that kept people away, are the same that are drawing attention.

* What are some factors to consider when identifying these hot spots?

Of course, every owner's situation is unique and factors like the legal entity involved, purchase date, adequate passive income that can be offset with the cost segregation study, etc., will need to be considered.

As far as I know, your assumptions about the tax implications are correct for non residents, it was one of the main factors that stopped the idea of investing in Spain for me.

The factors you mentioned are very important to keep in mind for any investment, but I like investing in areas I know. 

Most are also not considering between the new construction product and the entry level SFH with risk being the deciding factor.
