The real estate investing industry uses "Classes" to rank property performance risk, but there's NO agreed upon industry model:(Here's what we use for our Metro Detroit market:Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

However, I could not find any listings on multi-unit residential properties on the platform.  

Quote from @Louis Hamilton: The property is worth around 800,000 and has no mortgage on it.

How do I get to 5, 10, 20 properties with DSCR?

Quote from @Casey Wilson: Hi there, I was wondering if any Detroit-metro experts from the PB community could offer advice on what areas in the Detroit-metro area might be worth exploring for rental properties (ranging from single family homes to 5+ unit apartment complexes).

A 1031 exchange is for selling an investment property then buying another investment property. 

A fulltime property manager manages 140 leases. 

Turning the property quickly (you have to run it like an F1 pit crew)4.

That makes the investing and property management a LOT easier.  

They usually say something like Pkg 5-dfw 28 llc, with 10-20 properties in each LLC.
