Newly renovated.  

All of the apartments can use some TLC and I'll renovate and upgrade as tenants leave so I am able to increase rent.  

And take renovation loan as well of you need it.

Which is why over the last few years we've built up an inventory of properties that we haven't even renovated yet, they sit empty for the most part.

You could ask them about the cost to lease land, and I'd imagine they know people who can move them for you  They might know someone who specializes in renovating trailers that could give you a good idea of costs.

My one tenant moved out last week and I figured while it was open I would just renovate it all so both sides are completely renovated.

Can you also purchase and renovate your own projects for long-term buy & hold?  

It also has more than enough room for a 2 stall detached garage.My question is whether or not to include building a garage along with my regular house renovations. 

Make your offer based on what it would cost to renovate assuming you were hiring out the work.

.- Live and breathe the comps- Know what stuff UNRENOVATED and RENOVATED sells for per square foot- Know your DAYS ON MARKET- Know the types of rehabs your competition is doing, LEARN what those types or rehabs COSTSStarting out it's hard to know the difference between a GOOD deal and a BAD deal, but if you know your buy and sell numbers along with your rehab costs you can SMELL a deal a mile away and more importantly you can evaluate the deals agents / wholesalers send you and also make accurate offers on direct to seller and MLS deals you dig up yourself.
