Should I negative cash flow for a bit ?

[Jese Mbuya Gombalume]

Hey guys. So I’ve got a decision to make here on a property. It’s currently selling at a relatively competitive price , in fact it’s selling for under 100k below the Valued amount (last valued in this year February) 

The issue right now is that it currently has a tenant who’s signed a lease agreement ending next year February. The current rental price on the lease is way about 600 below my break even point (after mortgage and expenses).

I’ve got a job and I’m wondering if I should move in on the property and bear the negative cash flow until the lease ends? And then I could change terms to fit my pricing. What do you think, good or bad idea ?
