Prior to having her sign the new lease, I would have a conversation with her telling her that generally, you've enjoyed having her as a tenant, but you feel there have been instances where she is unclear on how problems are handled, so you want to direct her attention to the section that covers it, and tell her you've made updates (if you have), and make sure she understands going forward what is reasonable and unreasonable.Your other option is to just let the lease lapse into a month-to-month situation, and that way if she gets really bad, you can simply give her 30 days notice.

And just an aside if your property is vacant more than 60 days make sure you check your insurance policy you may not be covered many policy lapse on day 61... make that call you will be glad you did.I have had numerous discussions with investors since I started funding this stuff in 2002 that lost the entire investment because they did not read their insurance policy.. and if learned it the hard way my self it happened to me personally. 

My experience has been "Angels" want a BIG equity in the venture and when the deal lapses on time, they insist on being bought out - - at a premium. 

Still not a buying philosophy I would get on board with, but agree it makes more sense the longer you keep it (in most time situations where appreciation is inevitable with enough time lapse).

The time-lapse only goes through 2018 and there was a large amount of development in 2019 so even less land is available now.

Additionally, the Department of Homeland Security may be interested to know of any fraudulent activities, given his persona-non-grata status with lapsed green card in our gracious United States of America.

I allowed the contingency period to lapse on my first deal.

Also if time has lapsed since the plans were drawn up the county or city might have changed plans for the area.

Even more so, do the little things right, like @John Underwood mentioned. you would be surprised how many people lapse on keeping the essentials stocked.

You may want to see what your lender would charge for their forced insurance there are many cases in Florida of homeowners letting private insurance lapse and being charged lender placed insurance at a lower rate.
