Now I’ll discuss your numbers:
a family of 7, after taxes your $150,000 becomes about $100,000. you have 4 kids in yeshiva, each one asks for $11,000 meaning you pay $44,000 in tuition. You have rent of about $2500 a month and student loans and credit card debts of about $1000 a month. thats $42,000 a year right there. Car payments and car insurance cuts another $500 a month. there goes another $6,000. 4 shabboses a week cost you another $1000 a month, and there goes another $12,000. and now youre $4000 in the hole. and you have nothing to save so youll never buy a house. you cant afford a babysitter, yet alone a night out so you never go out. we havent even discussed summer camps.
Rent of $2500 a month = 4 bedrooms in Brooklyn. I guess that is OK. Not everyone can live in a two bedroom apartment.
student loans and credit card debts of about $1000 a month – Too high! what did you do to get 1000K a month is SL and you only earn 150K? And you already have four children paying tuition?
Car Payments & Insurance $500: High for one car, normal/low for two. I thought the advantage of Brooklyn is that you don’t need a car?
4 shabboses a week cost you another $1000 a month: “A’se Shabbatcha Chol V’Al Yitztarich L’Briyos”.
I think your numbers are slightly too tight, but somewhat reasonable given the expectations of an “in-town” family and their needs (and yes, consider that a lack of disrespect).
Also, what in the world happened to the first 10-15 years you were married?
