Advice needed on financing a rehab on a duplex

[Adib Rahman]

Hi all need your advice, I have a side by side duplex(Owned for 3 years and refinanced January 2021) and one of the longterm tenant just notified me that they are not going to renew the lease as they bought a new house, I'm happy for them.

I'm planning to renovate that side by ripping the carpet and add LVP, new carpets in the bedroom. Add new cabinets, A/C, and paint the whole unit.

I was wondering what would be the best way to finance this? Thanks in Advance
