Need math problem help!!!

My client had a home that was 23% rental for 130 months (March 2009- December 2019). In 2020, the entire home became rental and home sold July 2021. So, they had 18 months at 100%. I am trying to figure out the business portion of the sale. I'm having a tough time.

For real estate, I don't think you need to divide the sale between personal and business. Just report the full gain on 4797.

Have you gone through the worksheets in Pub 523? Note there are different calculations if the rental area is separate such as a garage apartment.

I would limit the personal portion to the last 5 years, and use the exclusion available for someone selling their residence if they have lived in it any portion of the last 5 years. For the first 8 years, I would calculate 23% of the gain and report accordingly.
