However, as I walk down the street in my city, I see tons of retail businesses that definitely do not comply. 

I’m actively seeking to purchase either a multi-family or duplex unit in the Columbus area  for a medium rehab project. 

You can break it out by general RE activities and material participation.

The one with the higher number has 1 active and 3 pending listings pretty similar to my property.  

Building a trusted team is key, so starting that process as you actively search for your market will put you in a strong position moving forward.

Material participation in the rental activities still required. 

This seems like the most active Portugal string.

The BRRRR strategy, which stands for Buy, Rehab, Rent, Refinance, Repeat, focuses on long-term investment, while the Fix & Flip approach involves purchasing, renovating, and selling properties for a profit.Investing in Airbnb rentals presents a distinct set of challenges, requiring active management and a thorough understanding of local regulations, but it also has the potential for higher returns.Here is a concise overview of the advantages and disadvantages of each method:Fix & Flip:Pros.- Potential for quick profits - Enhances property value - - Adaptable to market trendsCons.- High risk - Time-intensive - Requires substantial capitalBRRRR:Pros.- Builds long-term wealth - Generates rental income - Increases equityCons.- Complex process - Requires financing - Dependent on market conditionsAirbnb:Pros.- Potential for higher returns - Flexible pricing - Short-term commitmentCons.- Requires active management - Subject to regulatory risks - Income can vary seasonallyI wish you the best in your new venture.

RE is a lot more active and involved, even if you hire a PM and a GC which BTW eats up your returns.

@Kevin Hintz It's property dependent, obviously, but last year, I sold one a street back from the beach that they're cash flowing.
