QB Issue Resolution:

Assuming you are taxed as a sole trader, I recommend you have the following for owner/partner equity accounts  (one set for each partner if a partnership)
[name] Equity (do not post to this account it is a summing account)
>> Equity
>> Equity Drawing – you record value you take from the business here
>> Equity Investment – record value you put into the business here

so the memorized transaction would be

if you paid the mortgage from the business account
home office mortgage, 150, debit
equity drawing, 850, debit
bank, 1,000, credit

If you paid the mortgage from a personal account
home office mortgage, 150, debit
equity investment, 150, credit
