These fancy situations where the seller carriers some, the bank comes up with some and you come up with 15-20% I've never actually seen but some of the folks on BP will swear it's a thing. 

Mario,Most insurance carriers will not accept this type of breed under your landlord insurance, so please check there first. 

Once any of the detailed signal a flag it's no longer a happy harmless "Just a UCC filing" and as it states can enforce "security interests" as per the UCC rules.

I would be proactive about it, you need to shop before they non-renew you... that way you can honestly answered "NO" to the question, "have you ever been canceled or non-renewed for any reason" If you answered yes, you would then have to disclose the issue from the old carrier and then the new carrier would probably want you to add the stairs just to be safe. 

I also heard that using the words "credit" or "repair" in the addendum could signal a red flag to a lender.

You will get the trustee's deed sent to you within a few days or maybe a little over a week.One of my first steps is always to change the locks, just in case  the previous owners try to return and want to mess the place up worse than it probably already is.As for insurance, just make sure that your carrier and agent know that it is vacant because if they find out later that it is, they can cancel your policy.
