Very short seasoning period.

If you’re leaning toward selling your share, offering seller financing could definitely attract a wider pool of buyers while keeping the deal intact. 

I’m also open to exploring short-term rentals, private lending, or passive investing in funds—anything that maximizes returns while keeping risk and time commitments manageable.For context, I’d consider leaving my job if this could become a full-time venture that surpasses my current compensation (low-mid six figures).

So, long story short, I would just get an estimate from a firm and go from there.

I am thinking of starting with rentals, be it short term, midterm or longterm. 

To throw a wrench into things, if we were talking about real property/structures that were being short term rented, it's possible/likely that your depreciation period would be 39 years, not 27.5.However, a vehicle - which is what an RV is, regardless of how you're using it - is 5 year property.

You could go the house hacking route with buying MFU, etc.It MIGHT be interesting if you are a traveling nurse to turn your house hack into a short term or mid term rental while you are gone.

The owners of 100+ unit complexes are not individuals who will be swayed to sell by a good offer or the need to cut short term losses.

Its like a short-sale, its better than a foreclosure but has downsides as well. 

To qualify for installment sale you must selling an investment property, it was a rental for at least a short period.
