My property manager says there was no indication that the tenants are at fault.

However, they approach financial health from different angles.The 50% Rule is a quick estimate that suggests operating expenses (excluding mortgage principal and interest) will roughly equal 50% of the property's gross income.The DSCR is a more precise calculation (Net Operating Income / Total Debt Service) that determines if a property generates enough income to cover its debt obligations.Deal example:- Class C middle class neighborhood- 4bd / 2ba single family house- ARV: 190k- Purchase: 105k- Rehab: 35k- Market rent: $1,400-1,525- Section 8: $1,475- Property manager: 10%- Taxes: 125 month- Insurance $1250 yr- HOA: $55 month- purchased and rehabbed with all cash.

Especially if you are hiring property management.

Finally, as an aspiring/budding lender, I don't have as much access to mentors, but then again it's easier than rehabbing/flipping and probably easier than buying and holding and managing multifamily. 

And will you be utilizing property management firms to help out? 

We own one and manage multiple others on that same street.

Spending a ton on property management doesn't seem like the best move.

That means learning how to vet a manager.

Incensed deal flow by developing a large list of contacts of commercial mortgage brokers using LinkedIn.  

Being an agent is different than a w2 where you get guidance from a manager, or higher up.
