Inherited Property, then bought out family

In June  2019 my brothers and I inherited a house when my mother passed away.  Four brothers all together.  It was vacant until 8/1/2020 when it became a rental property.  On 9/17/2021, I bought out my three brothers.  The inherited price of the house was 630K (June 2019), when I bought them out on 9/17/2021 the appraisal was 780K.  Just trying to figure out how to report all this and if I can change the value of the house when I had to refinance it to buy out my brothers.
