But, I'm looking for advice on how to give them a non-renewal notice in a proper legal fashion to mitigate any issues after they move out. 1.

One I inherited and I will be shortly serving a 30-day notice because he is so much trouble.

There are systems to ensure your value of information is noticed and you get appropriate value for them, be a college professor.

If it’s a month to month lease and I wanted to change that I would give them 60 days notice.

Put the property in your own name with Fannie Mae (or other "traditional" GSE) financing, owner-occupied, at the lower OO rates, and rent the other units.

Things like:- limits of Liability of $1,000,000 per occurance- additional liability limits in an Umbrella policy- having them name you as an Additional Insured and requiring 30 day notice of cancellation- requiring that they hold you harmless and indemnify you if there is a claim- making their policy PrimaryThere are a lot of other things that can be required and what you ask form will depend on what is available, cost, and how it will impact getting a tenant.Talk to your Agent about what protections (alarm, fire doors, extinguishers, etc.) you need to have in place as a landlord for a business with children there all day.  

I'm writing a notice of the increase.Should I just create a notice without citing the reason, or list the reason as something like "anticipated wear & tear, etc.?

My tenants are on a month to month lease, at this time i also gave one tenant notice to rent increasing and the other notice that i would be not renewing their lease.Good luck and be open and honest with them!!

What you'll find is your return is higher when you leverage your money.Here's an example of a property I analyzed recently for another investor:Notice the highest return on my investment is the first year and it diminishes after that.Also notice I have $103,067.64 in equity on year ten.

Do we give her notice to get the dog out or evict her?!
