honestly, i do not know what you are looking for here. You seem to be lost which of those things you mentioned is a higher priority.
The forumers here look at your case and pin point that selling of one or two of your 'multiple' properties will make the situation immensely better. You agreed but not willing to do that.
So what you are looking for is a magical pill. You did not state how much capital other than your home, you could deploy. You state that your cash flow is getting very thin.
So what is it you want?
#1 stability and security?
#2 making it best for your kids and family?
#3 pushing wealth accumulation to the absolute best with very little capital?
You cannot have all.
"I want to live a better than average life , now have 4 child maybe have quite a few cars and bigger landed house to stay in"
"Although i own multiple properties, my bank account has been bleeding partly due to the bad housing market, resulting in lower rental yields, higher cost of living and stagnant salary.My salary will be used up quite quickly and sometimes i maybe have problems paying $1000-$2000 during month end for premiums or loans"
You want everything, with limited inputs. Basically you want a magic pill. I dunno about the others but I have no solution when a person is so confused as to what he really want.
