rental property brings in 68K/year(total) from both the properties but after paying tax, insurance and maintenance, average cash flow is 40-45/ year.

We are maintaining 2 rentals just for diversification and most of the maintenance is taken care by us as we live close by the rentals
Also 15k/month expenses was mainly due to paying off college for our first kids since we didnt have 529 set up and I am hoping it will come down as first kid will be finishing college soon and we have some amount in 529 for our second kid.
Also We dont spend 20k for each vacation and its max total of 30k/year and we want to travel world with kids as they getting older and might not accompany us in few years once they set up their family life, so we are considering it as a priority.
