I purchased and renovated a house with a separate legal mother/daughter apartment that I am preparing to Airbnb here in Central NJ. 

We would also be working with them to prepare them for refinance from Day 1.

Prepare for the inevitable, because bad things will happen.

I also will have a big promotion at work coming up that I will need to prepare for. 

The sooner you start these conversations, the better prepared you'll be when the right deal comes along.Local professionals can also be an invaluable resource.

They can also give you a better idea of how much you should be prepared to pay so you can cruise through your closing with confidence.And as you plan ahead for closing day, be sure to budget for your real estate agent’s professional service fee too, in case the seller doesn’t cover it.

Any tips on marketing or preparing a property near a military base for this kind of rental?

Also, if it's Lennar, be prepared for problems, insulation issues and therefore paper thin walls. 

Also, there’s much to delve into on of those scenarios, like what type of cashflow or investment do you want, etc. residential, multi-res, small multi-res, commercial, industrial, etc.There seems to be fewer deals around these days and this typically benefits the more experienced and skilled investors but there are always multiple investors that get “tripped-up” in these markets due to them relying on recent “fortunate” market circumstances only to realize the markets cycle and they weren’t prepared or didn’t underwrite properly to account for unforeseen potential.There are more considerations, but this is a start.

Could be that the funds that bought the loans are liquidating, or it could be repositioning in preparation for future business.
