Depending on which direction you're going with this, I have 1-2 contacts in mind for you.

@Marissa Contreras - I believe it depends on the size of your portfolio and what you have going on.

It will depend on how the properties are cashflowing 

Properties go to auction Highest bidder wins 30 days later or so you get a tax deed.. depending on title company you may need to wait 1 to 5 years before they will insure title..

$800 is probably pretty good in general - depending on your level of coverage which is the most important piece as rental dwelling policies can vary GREATLY

Depending where you are, some utilities are attached to the house and some to the person living there. 

There’s pros and cons to both so it depends on what your goals are.

@Marie Larcom depends on your lease language.Usually though, you can charge the tenant for May rent and deduct from SD.You can NOT though collect double rent in most states - meaning if you rent the property out with a lease starting in May, you will have to refund the prorated days to the previous tenant.

It depends on the profit/loss allocation on the operating agreement.

The procedure to build in the floodplain varies based on the jurisdiction.
