@Jay Fayz for SFR (1-4 family) Classifications are mostly opinion-based.Not aware of anyone tracking eviction rates, except Evictions Lab nonprofit that doesn't like landlords.Here's some info that might helpt:---------------------------------------------------------------------------------------------------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?

Buy not many people can do this and it requires very good book keeping.

Don't buy in the hood.

I am considering buy a home to flip.

Quote from @Scott Trench: Wait... the guy who buys all the ads (through Google) on BiggerPockets YouTube videos and attempts to reach BP viewers says that Tax Liens are the best way to build wealth, asking me repeatedly and agressively why I'm not doing it? 

I'm in Chesterfield as well, looking to buy.   

.: Quote from @Jay Hinrichs: when I was buying notes I did not even run credit.. but I only paid 10 to 20 cents on the dollar.  

These included cash buys for flips, seller financing, and subject-to deals.

Buy a $15 blender at Walmart, and they'll try to sell you an extended warranty.
