To illustrate this there are probably 50+  active MLS properties in North Philadelphia/South West Philadelphia and other lower tier neighborhoods at any given time where you can complete the BRRRR  method but the real estate is lousy.

For illustration purposes, I own 3 bedroom rentals in Mount Airy that rent for $2,950/M.

I'm not sure where you got your info from but this is an illustration of the fact that there's a huge amount of misinformation when it comes to investing overseas, here and elsewhere so be careful who you listen to.

To illustrate the other side, the rest of the island (outside of these resort zones) has historically been a place where owners can only do MTR's - 30 day + stays, but new legislation just got passed and it's looking like a minimum 90 day stay will be required.

Many turnkey operators tout strong rental returns, but will fail to illustrate the economic (employment, migration, infrastructure development, etc) projections necessary to make buy and hold viable in the long term.

Over time these numbers tend to increase.At $200 a door it takes a lot of units to make some money, which illustrates the importance of principal pay down, equity and appreciation when it comes to wealth generations.

The answers for her are NOT books and podcasts.You need to come up with illustrative exercises.

If your $115k property is now worth $230k, it's rent has to increase from $1,150/mo to $2,300/mo for true cash flow returns to keep pace (for illustration purposes).  

This criteria is for 1-4 and 5-8 unit programs.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 = 1.23DSCR lenders generally let you vest either individually or as an LLC.

The point I was trying to illustrate was what, @Ashton Levarek has confirmed.
