Also, what is the they typical length of the investment these type of investors are looking for?

Insurance companies use them because they know they can make 1 call and get a tenant anywhere furnished or unfurnished for any length of time.

If I have a listing that is generating a lot of interest, I will include a date that I need applications and fees by, and indicate that I will screen the best candidate of those that apply based on criteria such as length of lease desired, income, rental history, etc. 

Whether the courts of a non-series LLC state would respect the liability shields of a series LLC is not known.The IRS has issued proposed regulations providing insight into the IRS’ treatment of these entities:1) Each series within a series LLC will be treated as a separate entity for federal income tax purposes;2) Each series is allowed to choose its own entity classification independent of the classification of other series; and3) Each series should only be liable for federal income taxes related to that series.The proposed regulations do not address the entity status of a series organization for federal tax purposes nor do the proposed regulations specifically address whether each series within a series LLC should obtain a separate employer identification number (EIN) and file a separate federal tax return.Until final regulations are issued, I advise clients to obtain separate EINs and file separate income tax returns for each separate series which, I believe, helps each series maintain separate and distinct corporate identities, thereby reducing the risk anyone may be able attached a judgment to you or another series and pierce the corporate veil.Other ways to minimize the chance that one series may be held liable for liabilities of the entity as a whole (or another series) include the following:1) Create a separate bank account for each series (again, you’ll need a separate EIN to do this)2) Don’t commingle funds within series.3) Always sign documents in the name of the series.4) Properly document all loans between series.5) Conduct all transactions between series in an arms'-length manner at fair market prices using appraisals.6) Keep the assets and operations of each series separate from the other series.

Not trying to tell you who you should or should not accept, but there can be a big difference in types/severity of crimes, frequency (one time thing vs someone constantly getting arrested), and length of time since they were last arrested.   

Following usual and customary is important in keeping an individual at arm's length as a lender.

Do not talk at length at all about the incident to anyone.You could look into securing the pool better in the future, but again, if this is the typical Florida backyard pool set up, it might not be terribly easy.

That's called a non-arms length transaction and is NOT, under any circumstances, allowed.

This is especially the case in areas where it gets hot and you have asphalt shingles on massive roofs with huge rafter lengths on steep slopes leading up to little ridge vents.

Also, there is a limit to the length of your message but it was sufficient for my 40 second version.Anyways, thanks for all the feedback and would definitely like to hear more opinions on receiving calls.
