I want to send a notice introducing us as the new owners and giving them notice that in order to renew their lease they first must consent to a criminal, credit, and eviction screening under our new minimum qualifications/new lease terms for all persons over the age of 18 that live in the home and also inform them that rent will be increasing November giving them the chance to stay if they want  and meet our rental qualifications or decide if it's best for them to move.I want to know does this seem reasonable and if there are some things I should consider before moving forward with this plan?

We chose to spend a non-trivial sum, something like 15 years of flood insurance premiums, to re-slope the drive way (the big expense) and lawn and build a levee near the house to keep water away.

yeah 10-20k discount doesn't sound like much for a flood damaged property.I saw a realtor in Houston  here on BP mention that Houston Association of Realtors (HAR) added a feature to search for Harvey damaged homes , not sure if there is something similar in FL.

I understood the basic concept but was wondering if the definition just varied, or if I was missing something. 

What would down payment/financing look like for something like this?

I am less concerned with cost per square foot and more interested in something easy to install and super durable.

I have two step-sons about your age (I think) and they're very confident with some things- but not paperwork!  

So the question is: do you have something in your lease about dog poop and cigarett buds?

It would be so easy to find something obscure that is against code on your house. 

So, someone here could recommend something, but you wouldn't be getting the discounts that we might be seeing through our region/company/board.
