How can I refinance into an LLC or other entity?

[Christopher David Harris]

I bought a single family home 4 months ago and I am almost done with converting it to a duplex for my first house hack.

I put down 5% 
i’ll have built in about 25% equity (I’m guessing) so theoretically I should be able to cash out and get my down payment and rehab cost back,

What I’m not sure about, is where to begin with refinancing it into a company name?

Especially since the company will be brand new..?

Any advice would be greatly appreciated, thank you!
