I'm going to start gathering investment property quotes this week but wondering if anyone has any guidance on whether the cost varies depending on the type of rental?

I would also look at the year option to see how that varies.

After the 12 months payments above you qualify for the exception so you're back to regular/normal LTV's which depends on your occupancy  - second home/primary/investment - it all varies. 

Also, do you rely on Virtual Assistants or full-time staff to handle comms and requests?

The number of years you have to wait (called the redemption period) varies from state to state.

I would not anticipate much turnover so could be good cash flow over the long run, the question is the long-term appreciation… depends on your strategy and weather you’d be managing themselves or relying on unknown local property manager, contractors, etc.

I’m not saying partnerships aren’t good - but if you didn’t want to rely on someone else, I bet we could figure something out! 

It's just stupid for anyone involved in the transaction to rely upon it to convey good title at a later date. 

Relying on the seller's financier, which orders your appraisal, is a risk. 

And back to Chris's point, if your tenant knows that NNNs can vary widely, they may prefer a gross lease anyways.
