Live in renovation side or updated side

[Tamara Herrmann]

I bought a duplex about 1.5years ago and decided recently to move into as primary residence. One side is updated and the other side needs most likely extensive work. Would it make more sense to live in old side and work on it while living there and still make rent on other side while losing out on being able to claim expenses as tax deductible or live in updated side and loose out on rent for about 4-6month(1300/month) but be able to claim all expenses as tax deductible. I would estimate about $30-40k in renovations
