I'm not entirely sold on the idea of note investing over buying and holding rental properties. 

I do wonder if this could be accomplished with a 7 residential unit and using one unit as a short term rental though. 

There are various makes, select one that is overbuilt if you are putting it in a rental.

For STR definitely connect with a local RE broker focused or experienced with vacation rental regulations.

Standard down payment for a new primary mortgage typically range between 3%-5%If you need the rental income from the home you are departing you typically will need a fully executed lease and proof of 1st payment and security deposit

Both structures are treated as investment real estate and subject to the same issues as a sole ownership rental property. 

If they are not, then the Sheriff removes the individual from the property, gives you access, and then you can remove everything from the rental and place it on the curb.

Looking at residential properties to either buy and flip or use them as long-term rentals.

I’m not sure how many rentals you have but I have a few and have been able to negotiate a discounted rate with Irving Oil and Propane which gets passed on to my tenants with the property and then they set up their own personal account with Irving.
