If so, how did it go and are there any special restrictions you would run into if you tried?

SFR/MF, Class A/B/C/D, any special tenant accommodations?

I would highly suggest speaking with a real estate attorney and a CPA that specializes in real estate.

Working with REI takes highly specialized knowledge that it takes a couple years to develop.I'd suggest the other direction.

These are professionals with additional training and a stricter code of ethics.

For example, the lot I was looking at was zoned R-5, meaning you can have 5 lots per acre (every county has different names for their zoning codes too).

I would also review with the agent what types of safeguards the companies will expect (Hard wired smoke detectors, Central station alarms, extinguishers, etc.) as some of that will be cheaper to do during your rehab rather than laterIf you lease the commercial space out to certain businesses you may have to comply with additional codes. 

Hi, I specialize in solar land deals.

I would read the law regarding tax sales in your state real estate code or whatever section covers that.   

However, nobody would really know, especially since you are rural.But, as a cautionary tale, we just sold something off River Road near Salinas/Las Palmas/Indian Springs, and MoCo made the seller rip out a finished apartment above the garage to stay within code compliance.I would start the permit process from the very beginning or not at all.
