For example the house has a section that used to be a sunroom or screen porch and was added many years ago as part of the house and somehow none of this work was done with papers, also the basement was finished with a bathroom, kitchen and non-compliant bedroom but the entire basement is around 6’8” instead of 7” (minimum per code) so inspector is saying that the entire basement was not suppose to be finished and it sounds like he wants it all removed or to apply for a variance that he is letting me know upfront most likely wont be approved.

They'll have experience with this, dealing with tenants with disabilities, and any local laws that apply.

Second homes can be rented out as a STR with the rule being just under 6 months out of the year but again change of circumstance applies. 

Any tips or pointers to apply to make myself more "prepared" to be an investor would be great!

Tenants develop a shortlist by applying four filters, as illustrated below.Working with your team, translate your tenant pool's rent range, needs, location, and wants into a physical description of properties that will match.

Make sure it applies to your local area.As for multi-year leases, we've used two-year only leases for the past decade.  

How does this apply if the tenants violate the lease ?"

Also my PM mentioned no pets deterred people from applying too.

If that's the case, the property would be considered an owner occupied property and not an investment property from a value standpoint which means a CAP rate won't apply in this circumstance.
