I prefer the chart of accounts to look like this, all accounts are fixed asset type
124 some street
>> land
>> building
>> >> accumulated depreciation building
Assuming y'all owned the property and are now putting it into the business do a journal entry
debit fixed asset building for the full fair market value
credit partner equity investment partner one for his share
credit partner equity investment partner two for his share
You should have, need to have, a written partnership agreement registered with the state, and an IRS FEIN for the partnership
