The seller already has given me a good deal on the property due to her being forced to return to NYC for work post-covid (seller is paying $20K out of pocket after overpaying for the property 2 yrs ago, and sellers agent is taking a commission cut to make the deal work).

Did the IRS have issues with the 100 hours of material participation for only two months out of the year?

Quote from @Taylor Davila: What is the average cost of converting a single family home into a duplex? 

The writer is predicting the future, based on current information.  

For no/low-cost seller leads, I'd also recommend FSBO via zillow or realtor.com.As far as commission structure, the post-NAR settlement rule is that you are only allowed to collect the amount negotiated on your buyer agreement.

The bigger the property, the different the agent on the commercial side.

I added my latest rental property to Stessa then clicked the button to syndicate with Zillow, Trulia, and Hotpads.

Any thoughts / advice would be helpful Without knowing anything about your business, just based on your post I'd put the money in the business.
