My boyfriend and I are buying a house together. We will have a joint checking that we will pay all the bills out of (including joint entertainment and groceries) and a savings account for sinking funds (can you tell I'm in charge of the money? ) My question, should I start a second TBM workbook for our joint expenses (I have the print out version)? Or should I include it in my workbook? Also, any other tips/tricks for moving in together? Sinking funds you wish you had started? Thanks!
