Sell house or new mortgage for reinvesting

[Thomas Pecoraro]

This is my situation i have about 9K in the bank i just bought and renovated a small income property last year and i own a home that i live in and it too also brings in profit. My third property my mother lives in and is 100 percent paid off. I have about 1-3 properties i have found ran some numbers, that i want to start biding on soon for rental income properties. I dont know what would be best to take out a new mortgage for the house or renovate it and sell it ? But then i will still have to find a place for my mother. house that is paid off is about 300-350k . Not Sure if anyone has had a similar situation please share your experience if you did and outcome or just your opinion 5)- ks!
