Buyout, OMI or Ellis act?

[Tob Siripak]

I recently bought a triplex in San Francisco. There's 1 section8 tenant living in a studio, a family in the 2 bedroom unit. The vacant unit is big studio. This family is a protected tenant. I'm not sure if I should pursue buyout or OMI or Ellis act with the whole unit. I have no idea on how much the buyout would cost. 

- Since I have an empty unit now is it possible to do the buyout?

-Which one would be worth it for a long run?

Ellis act seems to be a big decision for me to have to take it out of the market for a certain amount of time. But I'm not sure if the tenant can request whatever amount they want for the buyout? 

Would love to hear any suggestions or experiences anyone has had with evictions here in SF. Thank you very much.
