House-hacking off to a rocky start..

[Zach Naeger]

My wife and I have done a couple live-in flips and really loved it, but with the arrival of our daughter we decided maybe it wouldn't be a great idea to have an infant in a construction zone. So, we decided to buy a duplex, live in one of the units and just flip houses like normal people. The duplex we bought had one of the units occupied by a woman and her son and they had been there for a couple years. When we moved in we met with her and told her we would continue charging the same amount of rent she was being charged previously (which is about half of what other units bring in the area) but we wanted her to move out by April 1, which was about 2.5 months away. Things haven't went smoothly since. She was two weeks late with the rent, she won't quit smoking inside though we've asked her to, a few other annoying issues and a lot of lying. When I tried to collect the rent for the last month she wouldn't answer the phone or the door for a couple weeks. We also had a pretty ugly run in one night when I asked her to stop smoking weed downstairs (all her smoke comes right into our unit). I finally caught her outside and told her that as long as she's out by the first we won't worry about the last months rent. She said she wouldn't pay it anyway because her deposit is the last months rent (we never received a deposit). I'm not really worried about the money, but I am worried she's not going to leave. What should I do if she doesn't? I'm very new to land-lording and there was never any kind of a lease with her previous landlord. We did have her sign a statement when we moved in just saying she would leave by April 1st. and the rent would remain the same as before.. in hindsight we should have done a better job with that.
