thanks @Mary B. and @Suzie R.

The white cabinets with the Wilsonart "Spring Carnival" or "Autumn Carnival" along with Stainless Steel Appliances... is lovely.  

Obviously it can vary across property class where Class A properties have lower returns compared to Class B, and B will have lower returns that Class C. 

The condo vibe is upper middle class in the sense of clean, neat, new white cabinets, stainless steel appliances, etc. 

We had no recollection of a foundation issue, so no, that was not addressed before though we've had steel beams put in by an engineer who assessed the structure of the entire property twice in different occasions and never made a mention of it, hence our lack of awareness for this particular line item in our old inspection report.

I am looking into the Memphis market due to thats what I know and looking for B and C class properties in which there is value add opportunity.

Where are the best places to invest in A- to B+ and C+ to B- SFRs properties?

Lumber and steel are up and that's pinched my returns. 

You should contact @Christopher B. and @Payton Abernathy.

My investment philosophy when it comes to real estate is to buy in lower class areas (B- and C+ areas), this way, there's always a demand for affordable housing.
