TTC now or later?

This year has been a tough one. My niece was diagnosed with cancer and A few days after that we were told our landlords were not renewing our lease and we needed to move. We ended up at my mom's, as our optionswere  limited. We wanted to TTC a while ago, but life had other plans for us. It is crazy to TTC while living at my mom's or wait until we own a house? I'm in my 30's and don't want to wait another year to have my first baby.
