I don’t know the backstory of the author or her subject; I’m simply using their arguments to illustrate a point: it’s all about perspective.I hang out with a lot of realtors/investors/entrepreneurs.

My contemporaneous notes on that worksheet will illustrate the decision process.

But your post does really illustrate my point 

The (BRRRR) process of growing your portfolio is illustrated below.This method is how successful investors grow their portfolios over time.In summary, you can’t afford to buy in low-cost locations if you want to achieve financial security with the least total capital possible.In SummaryLocations with high appreciation:Enable you to to achieve permanent financial independence because prices and rents keep pace with inflation.Reduces the total capital required to acquire the number of properties you need to replace your current income.Locations with low appreciation:Provide short-term financial freedom because rents and prices will not keep pace with inflation.

For comparison, here are the long-term rates of return from some of the greatest investors of our time:Warren Buffett:  29% over 13 yearsPeter Lynch: 29% over 13 yearsMichael Burry: 22% over 8 yearsCharlie Munger: 20% over 13 yearsBill Ruane: 18% over 13 yearsThis should illustrate how unlikely you are to passively turn $22K into $2M in 10 years (e.g. turnkey investing).  

If they will do a loan with less than 1, the pricing takes a hit.I've included an example below to help illustrate this.

If they will do a loan with less than 1, the pricing for the rate takes a hit.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 is greater than 1.2 so will qualify for 1 ratio and 1.2 ratio programs.DSCR lenders generally let you vest either individually or as an LLC.

To illustrate my point, there are hordes of Americans who have bought property in Mexico.

Slightly different set of facts, but it illustrates that typically the property owner is responsible for their own lateral, regardless of distance, depth and crossing (or boring under) public streets. 

The process I propose is illustrated below.
