To nail down where there are opportunities in B/C class neighborhoods would be difficult - I'd recommend getting a realtor that works directly with investors and knows where to find what you're looking for.I'm biased with PHX / AZ, but historically it's proven itself. 

Nail holes need to be filled where tack strips where, but ripping the staples from the hardwood resulted in several rough spots that need to be sanded down.We have no experience with hardwood refinishing- what are our options to avoiding a full scale hardwood refinish?

Are ya'll getting ready to nail a bunch of BRRRR deals?

Not sure I'm nailing the analysis.My questions: are there still cash-flowing B-class properties to be had in areas like Pleasant Ridge, Norwood, Walnut Hills?
