How to report sale of part of vacant land when the whole land was purchased in the same tax year

[bsmith]

my client has purchased a 2.5 acre vacant non income producing land in Feb 2022 and sold .5 acre (1/2 acre) during the same year 2022.  How do I report this partial sale and the profit?

Divide basis by 5 and use that for the .5 acre sale?

Is he a real estate developer?  Maybe Schedule C.  Not really enough information here.

I agree, also...did it gain any equity that would raise the FMV at time of sale/
