Don't do something that will make you lose sleep at night, but also remember that there is great power in smart leverage. 

With 5 tenants in there, he doesn't want people disturbing them without knowing we're on the same page. 

You can sleep in a car.

I've seen  reference to prior fire damage, violent crime, warnings about lead paint, etc.If it helps you sleep at night or you feel some type of personal obligation you can warn them.I would just wash off the eggs.

This is from the Provo Code 14.06: "“Family,” unless otherwise expressly provided in this Title means:(a) One (1) individual living alone; or(b) One (1), but not more than one (1) at the same time, of the following groups of individuals described in subsections (i), (ii), or (iii) who together occupy a one-family dwelling unit as one (1) nonprofit housekeeping unit and who share common living, sleeping, cooking and eating facilities:(i) A head of household and:(A) All persons related to the head of household as a parent, child, grandparent, grandchild, brother, sister, uncle, aunt, nephew, niece, great-grandparent or great-grandchild by blood, marriage, adoption, guardianship, or any other duly authorized custodial relationship; and(B) Not more than two (2) additional related or unrelated persons, including but not limited to, personal care or personal service providers; or(ii) In R1 zones located within neighborhood areas described in Subsection (c) of the definition of “baching singles” in this Section, two (2) related or unrelated individuals and any children of either individual, if any; or(iii) In all other zones, three (3) related or unrelated individuals and any children of either individual, if any."

It's just all about what is best for you and your goals and what kind of returns you want while still being able to sleep a night. 

Back then, in the 80's, I needed 30% down, but the safety of the fixed rate enable me to sleep better at night.

This way, you don't unnecessarily disturb tenants by weeding out the tire-kickers and looky-loos as much as possible and find the serious buyers who are ready, willing & able to buy the property. 

When we refinish the basement, we just lay a new floor over the old asbestos tiles and dont disturb it.
