We have a connection with a private money lender that we are hoping to work with.

@Gary Headrick I private messaged you and am wondering if you would share some of your "other options" that you mentioned.

You should’ve given them the proper notice that you were entering and then followed through.

There are tenants still living in the property.Is it better to simply evict them and start over or should we post notice that we will be needing them to sign a lease?

Most times, you just have to give them 24 hrs notice. 

If you're interested in an Orlando meet up, I can add you to a free private group I've found through networking with other local investors here on BP.

I want to get myself into a triplex or fourplex, but I'm noticing these are hard to come by.

And then there is this whole other world of private money and crowd sourced money. 

It can be your first stop and last stop of the day.RECORD KEEPING: Always make sure you keep minutes of the incorporation meeting (decide on business entity and set up by-laws), shareholders meetings at least annually and give proper notices.

Usually you need to give the tenants at least 30-day written notice of the increase as well as housing.
