Also, these are people that are renting a room in a house, they clearly don't have money to hire a lawyer for such an unreasonable reason. 

I've talked to a few companies but they all seem to charge unreasonable high management fees.

Focus on following this and if a tenant asks for something unreasonable learn to say no (if that is the problem).  

It's difficult to say why you think these quotes are unreasonable without providing the coverage and the cost.Are they unreasonable because they don't insure what is needed for the price?

Chances are you may end up in Court again at some point and you don’t want the Judge to have a preconceived opinion that you are unreasonable or your rentals are crap.

The family in the inhabited unit was on a month-to-month lease until a couple of months ago, at which point I had my attorney send them a 30-day notice of nonrenewal of lease.The tenants are effectively ignoring the nonrenewal notice, and my attorney has reached out directly to these tenants a number of times in order to offer them more time to vacate, as they are a little older, aren't in the best physical health, and have an adult son for whom they care.My attorney is communicating with the tenants on my behalf, exclusively, as I wanted to be as legally cautious as possible.The tenants are not responding to my concession to allow more time to vacate (they asked for an additional six months - unreasonable - I countered with two months), and they still claim to my attorney that we have a valid lease, despite there being a valid nonrenewal notice having been issued.

If this is not specifically addressed in the lease and you have no evidence of a professional cleaning prior to occupancy, it's an unreasonable expectation.

What I’m getting from this is that it’s not unreasonable to focus my efforts here and find creative ways to achieve financial independence in my expensive market.

An unreasonable seller would listen to bad advice on the internet.

For instance, there are a few well known institutional lenders here in town who have horrible reputations centered around not getting loans closed, having poor appraisals or unreasonable underwriter guidelines...it doesn't matter how good a rate or fee is if nobody in town wants to work with them!
