My student rental property was registered as a fraternity without my knowledge or permission, which I would have never given.

If you're applying for a Conventional/FHA/VA/ or USDA loan, then they will do a "global cash flow" where they take into account your PITI (Principal + Interest + Taxes + Insurance (hazard and flood) on all properties (second mortgages included), HOA payments, car payments, student loan payments, credit card payments, and installment loan payments in the numerator and your gross income in the denominator.

As a result, I have become a student of marketing to find properties since early in my investing career.

While the market in Denver seems to be solid, and everything I find in my research seems to confirm that, I'm unsure of what the rental market is like and for what demographics (family, students, traveling nurses).
