Two driveways with private side entrance to the lower level.

Essentially, you have to have a separate entrance.

If you are afraid to exercise your rights or fear your tenants take a witness with you to protect your rights.Tenants that are given legal notice can not legally bar entrance by a landlord and do not need to be present for the landlord to enter.

Its $250 entrance fee and first three months free for Lot Rent. 

A separate entrance is probably best, but not necessary.

This strategy is great, but it fluctuates depending on the time of year, you probably won't live for free because it is more challenging since you are only Airbnbing a small space or basement unit.3) MTR - this is a good in between style of creative strategies since you can furnish a place nicely that would rent out on Airbnb but you want a long-term high quality tenant like a travel nurse or corporate rental that stay for 2-3 months vs. under 30 days for most Airbnbs.Combining strategies is the best way to go, ideally, you would find a house with a separate entrance or walkout basement, live upstairs in the one of the bedrooms, rent out the other upstairs rooms and STR/MTR/LTR the bottom unit.

PGE went up by ~25% in the winter/fall, not much in the summer/spring.Nurses like privacy (private entrance), quiet, utilities included (inc internet) and blackout curtains because most of them work the night shift.

For example, are there any shared areas (entrance/exit, hallways, kitchen, bathrooms) – or are they separated and locked units?

We have a single family home that's been modified and now has an attached companion unit with its own kitchenette, bathroom and side entrance. 

I purchased a property that has an awkward basement entrance from the side due to a small addition at one point.
