Hi Scott, I don’t know a whole lot about tax lien investing as but I have been learning a bunch about it I suggest you get yourself a copy of the 16% solution by Joel Moskowitz and then go to the tax collectors went for the county/s you are interested in and learn as much as you can.

Suppose I’m doing a BRRRR deal and my after renovation appraisal comes back significantly lower (eg ~10-20%) than the tax assessments on comparable properties, can I use that assessment as additional evidence to an appraiser that a bigger value is warranted?

Hope this additional info. helps & God bless. 

Additionally, Greenville benefits from a strong and diverse economy, with thriving industries such as advanced manufacturing, healthcare, technology, and automotive.

My suggestion would be to select someone with the most forum posts or most reviews.

But does anyone have additional thoughts on how I can connect with these potential sellers, especially multifamily property owners?

I will also look at acquiring commercial properties on the market in addition to using tax liens. 

Unless, like Bill suggested, there is some kind of local restriction on the property usage that you have been unknowingly violating.

Would love to hear your suggestions about JV/partnership strucrure - I don't have enough equity to buy more properties to myself.I want to find an equity partner that will bring up the cash, and I will be responsible for finding the deal, rehab, day to day management.My strategy is BRRRR.
